TR‐AKA: A two‐phased, registered authentication and key agreement protocol for 5G mobile networks

With the development of mobile communications, the authors step into the 5G era. 5G-AKA is intended to serve as a certification standard for users to safely and stably enjoy 5G mobile services. However, recent research proves that some attacks may happened based on information deciphering and message replay. In addition, the authors found that some variants of 5G-AKA are also at risk of linkability attacks. Therefore, in order to solve the above-mentioned risks, the authors propose a two-phased, registered protocol TR-AKA. This protocol finishes two-way authentication between the user and the home network through only two message-sending rounds, and a temporary identity variable group is applied to replace the real information for transmission. A newly designed variable is also used to strictly control the increase of the sequence number to promote the sensitivity of freshness. Finally, the authors choose the Tamarin tool to prove that TR-AKA has achieved authentication and privacy-protection objectives, and further discussions have also verified the rationality of the protocol design.

Neue Räume – neue Rollen? Ungewissheit im Kontext der Temporären Organisation

Dieser Beitrag in der Zeitschrift „Gruppe. Interaktion. Organisation. (GIO)“ diskutiert die Auswirkung von Ungewissheitserleben und neuen betrieblichen Handlungsräumen auf die Rollen- und Identitätskonstruktion von Mitarbeitern und Mitarbeiterinnen. Ungewissheit ist nicht erst seit Auftreten der Corona-Pandemie eine der zentralen Herausforderungen hinsichtlich der Entwicklung von Arbeitsbedingungen in Organisationen. Digitalisierung und Virtualisierung, Wissensarbeit und Projektorganisation sind Trends in der Arbeitswelt, die fragen lassen, wie sich soziale Identität und Rollenverhalten in Temporären Organisationen unter dem Einfluss von Ungewissheit entwickeln. Hierzu wird im vorliegenden Artikel das Verhältnis von temporären Repräsentationsräumen und Identität sowie neuen Rollen in Temporären Organisationen, unter besonderer Berücksichtigung von Projektstrukturen, untersucht. Es wird deutlich, dass durch die räumliche Neupositionierung der Temporären Organisation und dem damit verbundenen Wandel der Mitarbeiterrollen der Identitätsarbeit auf Basis der eigenen Erwerbsbiographie eine immer größere Bedeutung zukommt.

The Impact of External Contextual Factors on Teaching Candidates

The formation of a teacher’s identity is considered a dynamic process influenced by internal and external contextual factors. This article explores the impact that external contextual factors have on teacher candidates’ identities by presenting the findings of an empirical qualitative study that investigated the relationship between teacher candidates’ beliefs and their demonstrations and representations of teaching and learning on a nationally standardised portfolio assessment. Metaphor analysis and stimulated recall were used to explore this relationship. The study found that teacher candidates’ teaching demonstrations while student teaching and representations of teaching found in a nationally standardised portfolio assessment were severely constrained by cooperating teachers and scripted curriculums. However, the study also found that candidates could articulate the differences between their beliefs about teaching and learning and their demonstrations and representations of teaching and learning. Candidates routinely made suggestions in the portfolio assessment to align their future teaching more closely to their metaphors for teaching. The study concluded that candidates did not change their beliefs but took up temporary teaching identities based on these findings. They found ways to navigate the assessment and their (teaching) context while remaining committed to their teaching identity and beliefs about good teaching. This article suggests how education system contexts impact the formation of teacher candidates’ identities and what teacher education programmes need to do to strengthen candidates’ identities in the face of negative external influences.

Permanent Temporality: Race, Time, and the Materiality of Romanian Identity Cards

Documents, in particular identity cards, mediate relationships between individuals and institutions. Their materiality matters and actively impacts how states govern populations and their movements. In this paper, I examine one such object, the Romanian identity card. Focusing on its temporality and agency, I explore how objects and technological procedures enact race. In Romania, people without an address or proof of residence—many of them members of segregated Roma communities living in deep poverty—can only receive a temporary identity card, the Carte de Idenititate Provizorie (CIP). CIP holders do not enjoy full citizenship and are deprived of various rights, such as the right to travel without a passport within the European Union. They are also exposed to heightened surveillance as they must apply annually for a new CIP. Starting from the material object of the CIP, I explore how race comes into being as a relation at the intersection of various temporalities that are folded into the rules and bureaucratic practice entailed in its issue. I offer the concept of “permanent temporality” to analyze how racialization occurs in practices of governing people and their movement in Europe.

An efficient and provably secure key agreement scheme for satellite communication systems.

Satellite communication has played an important part in many different industries because of its advantages of wide coverage, strong disaster tolerance and high flexibility. The security of satellite communication systems has always been the concern of many scholars. Without authentication, user should not obtain his/her required services. Beyond that, the anonymity also needs to be protected during communications. In this study, we design an efficient and provably secure key agreement scheme for satellite communication systems. In each session, we replace user’s true identity by a temporary identity, which will be updated for each session, to guarantee the anonymity. Because the only use of lightweight algorithms, our proposed scheme has high performance. Furthermore, the security of the proposed scheme is proved in the real-or-random model and the performance analysis shows that the proposed scheme is more efficient than some other schemes for satellite communication systems.

Is There a Reformation Into Identity Achievement for Life After Elite Sport? A Journey of Identity Growth Paradox During Liminal Rites and Identity Moratorium.

Athletes’ identity development upon retirement from elite sport was examined through a model of self-reformation that integrates and builds on the theoretical underpinnings of identity development and liminality, while advancing seven propositions and supporting conceptual conjectures using findings from research on athletes’ transition out of sport. As some elite athletes lose a salient athletic identity upon retiring from sport, they experience an identity crisis and enter the transition rites feeling in between their former athletic identity and future identity post-sport life, during which a temporary identity moratorium status is needed for identity growth. Given the developmental challenges encountered in moratorium and psychosocial processes necessary to establish a new, fulfilling identity for life after elite sport, we identified key conditions, triggers, and processes that advance how a journey of identity growth paradox experienced during liminality serves as a catalyst toward identity achievement. Elite athletes must be encouraged to persevere in this challenging identity search and delay commitments for as long as it is necessary to achieve identity growth despite experiencing uncomfortable feelings of confusion, void, and ambiguity during the liminal phase. Reforming into an achieved identity for life after elite sport would corroborate the successful navigation of transition, as elite athletes evolved into a synthesized sense of self by cementing, through a negotiated adaptation pathway, constructed identity commitments that will provide new beginnings and meaningful directions to their life after elite sport.

Taiwanese Working holiday makers in rural and regional Australia: temporary transnational identities and employment challenges

ABSTRACT Working Holiday Makers (WHMs) from overseas have been a valuable source of employment in rural and regional Australia. This is one significant part of a growing resort to temporary migration to meet employment problems especially in regional areas. Little is known about the experience and contribution of Asian WHMs despite the presence of significant numbers, especially from Taiwan. Most Taiwanese WHMs are young educated women who have moved in search of cultural experiences and reasonable incomes. Analysis of media reports in Australia and Taiwan reveals an entirely negative perception of such migrants and their everyday circumstances that denies diversity, agency and contribution to regional economies. Taiwanese media are more likely to focus on exploitation. Being a WHM provides a distinctive transnational experience balancing travel as a cultural experience with a marginal employment experiences. New research is required to redress this limited context and evaluate the actual significance of these substantial temporary migrant flows.

Temporary musical identity as a tool for rebuilding social place

The armed conflict in Colombia leaves many families with no other option than to be displaced, which affects their social status and identity. This article reprises a qualitative study that analyses the life histories of eight families, all of whom were victims of the armed conflict, whose children participate in the Batuta National Foundation’s ‘Music for Reconciliation’ programme. The results of the study indicate that displacement impacted identity, resulting in the unsettlement of the social place of the participants. This was due to their anonymous state on arrival at their new places, with no support networks or social recognition. Together with the distrust created by the violence experienced, this led to attitudes of isolation, through which the individual became increasingly vulnerable to the dynamics of violence. This text analyses the concept of temporary musical identity, and the results show the possibilities that collective musical spaces offer for restoring the social place of the participants.

Heterogeneous Cross-Domain Identity Authentication Scheme Based on Proxy Resignature in Cloud Environment

Based on proxy resignature, the signature transformation between trust domains of different cryptographic systems is realized with the help of the cloud authentication center, so as to achieve cross-domain access between users and cloud service providers in heterogeneous environment. Hierarchical ID tree realizes the uniqueness of identity in communication, and the security of heterogeneous cross-domain identity authentication is enhanced by the two-factor authentication of “password + key” and temporary identity replacing real identity. The security of the scheme is proved under the CK model, which can anonymously trace entity identity, resist replay attacks, replacement attacks, and man-in-the-middle attacks, and the simulation experiment is carried out. By searching it in related fields, no paper on heterogeneous cross-domain identity authentication based on proxy resignature has been published yet. The results of this paper show that the proposed scheme has better computing performance and higher security.

An Efficient Secure Electronic Payment System for E-Commerce

E-commerce implies an electronic purchasing and marketing process online by using typical Web browsers. As e-commerce is quickly developing on the planet, particularly in recent years, many areas of life are affected, particularly the improvement in how individuals regulate themselves non-financially and financially in different transactions. In electronic payment or e-commerce payment, the gateway is a major component of the structure to assure that such exchanges occur without disputes, while maintaining the common security over such systems. Most Internet payment gateways in e-commerce provide monetary information to customers using trusted third parties directly to a payment gateway. Nonetheless, it is recognized that the cloud Web server is not considered a protected entity. This article aims to develop an efficient and secure electronic payment protocol for e-commerce where consumers can immediately connect with the merchant properly. Interestingly, the proposed system does not require the customer to input his/her identity in the merchant’s website even though the customer can hide his/her identity and make a temporary identity to perform the service. It has been found that our protocol has much improved security effectiveness in terms of confidentiality, integrity, non-repudiation, anonymity availability, authentication, and authorization.

Violence Hates Games? Revolting (against) Violence in Michael Haneke’s <i>Funny Games U.S.</i>

Violence Hates Games? Revolting (against) Violence 
 in Michael Haneke’s Funny Games U.S.
 Abstract: This article aims at exploring Haneke’s Funny Games U.S. as a protest against violence employed in the mainstream cinema. Satisfying compensatory needs of the spectators, constructing their identities, and even contributing to the biopolitics of neoliberalism, proliferating bloodthirsty fantasies put scholars in a suspicious position of treating them as either purely aesthetical phenomena or exclusively ethical ones. Haneke’s film seems to resist such a clear-cut binary; what is more, it contributes immensely to the criticism of mainstream cinematic violence. Misleading with its initial setting of a conventional thriller, Haneke employs absurd brutality in order to overload violence itself. The scenes of ruthless tortures are entangled in the ongoing masquerade, during which swapping roles, theatrical gestures, and temporary identities destabilize seemingly fixed positions of perpetrators and their victims, and tamper with the motives behind the carnage. As I would argue, by confronting its spectators with unbearable cruelty devoid of closing catharsis, Funny Games deconstructs their bloodthirsty desire of retaliation and unmasks them as the very reason for the violence on screen. Following, among others, Jean-Luc Nancy and Henry A. Giroux, I would like to demonstrate how Haneke exhausts the norm of acceptable violence to reinstate such a limit anew.

Identity and Recognition in the Case of ‘Dalits’

Recognition plays an important role in shaping up the personality of humans in social and political context. Recognition is the act of accepting or respecting other beings or group, a ‘vital human need’, an important means of valuing the other. In this paper, we focus on how language plays an important role in recognition and misrecognition. We address this issue with specific reference to ‘Dalits’. ‘Dalit’ as an identity is created by the subjects of recognition in retaliation against the misrecognition by others. We trace how the identity of ‘Dalits’ is formed and we argue that ‘Dalit’ identity can only be a temporary identity in realizing an egalitarian society.

Changing Logics in Healthcare and Their Effects on the Identity Motives and Identity Work of Doctors

Recent literature on hybridity has provided useful insights into how professionals have responded to changing institutional logics. Our focus is on how shifting logics have shaped senior medical professionals’ identity motives and identity work in a qualitative study of hospital consultants in the United Kingdom’s National Health Service. We found a binary divide between a large category of traditionalist doctors who reject shifting logics, and a much smaller category of incorporated consultants who broadly accept shifting logics and advocate change, with little evidence of significant ambivalence or temporary identity ‘fixes’ associated with liminality. By developing a new inductively generated framework, we show how the identity motives and identity work of these two categories of doctors differ significantly. We explore the underlying causes of these differences, and the implications they hold for theory and practice in medical professionalism, medical professional leadership and healthcare reform.

Milk donation after losing one's baby: Adopting a donor identity as a means of coping with loss

This is a study of bereaved mothers' donation of human milk to nonprofit human milk banks following their baby's death. Whereas much has been written about the biological and medical aspects of milk donations in times of loss, much less attention has been given to the psychosocial aspects of this phenomenon. I build on research of motivations for philanthropic giving in times of crisis and loss, and focus on the role of donor identity for explaining bereaved mothers' milk donations. Through a content analysis of 80 bereaved donors' personal testimonials, I demonstrate the role of a donor identity as a transformative identity in these women's process of coping with their loss. Taking on a temporary milk donor identity helped the women in this study reconstruct their shattered identities as mothers and healthy females and served to enfranchise them as bereaved mothers.

A pairing‐free identity‐based handover AKE protocol with anonymity in the heterogeneous wireless networks

SummaryNowadays, seamless roaming service in heterogeneous wireless networks attracts more and more attention. When a mobile user roams into a foreign domain, the process of secure handover authentication and key exchange (AKE) plays an important role to verify the authenticity and establish a secure communication between the user and the access point. Meanwhile, to prevent the user's current location and moving history information from being tracked, privacy preservation should be also considered. However, existing handover AKE schemes have more or less defects in security aspects or efficiency. In this paper, a secure pairing‐free identity‐based handover AKE protocol with privacy preservation is proposed. In our scheme, users' temporary identities will be used to conceal their real identities during the handover process, and the foreign server can verify the legitimacy of the user with the home server's assistance. Besides, to resist ephemeral private key leakage attack, the session key is generated from the static private keys and the ephemeral private keys together. Security analysis shows that our protocol is provably secure in extended Canetti‐Krawczyk (eCK) model under the computational Diffie‐Hellman (CDH) assumption and can capture desirable security properties including key‐compromise impersonation resistance, ephemeral secrets reveal resistance, strong anonymity, etc. Furthermore, the efficiency of our identity‐based protocol is improved by removing pairings, which not only simplifies the complex management of public key infrastructure (PKI) but also reduces the computation overhead of ID‐based cryptosystem with pairings. It is shown that our proposed handover AKE protocol provides better security assurance and higher computational efficiency for roaming authentication in heterogeneous wireless networks.

Secure mutual authentication and automated access control for IoT smart home using cumulative Keyed-hash chain

IoT platforms face huge challenge in deploying robust authentication mechanisms due to the fact that edge devices and resource-constrained devices may not have enough compute and storage capability to deploy and run existing mechanisms, which involve in general complex computations. In this paper, we propose a secure lightweight mutual authentication and key exchange protocol for IoT smart home environment based on temporary identity and cumulative Keyed-hash chain. Nodes can anonymously authenticate and establish session with the controller node using dynamic identities and symmetric keys in an unlinkable manner. Moreover, the enforcement of security policy between nodes is ensured by setting up a virtual domain segregation and restricting nodes capabilities of sending and receiving instructions and commands to or from other nodes. Cumulative Keyed-hash chain mechanism is introduced as a way to ensure the identity of the sender (through challenge-response). In addition, we capitalize on fog computing concept to improve identity assurance. Finally, we formally evaluate and prove the security of our protocol by using the Burrows-Abadi-Needham (BAN) logic and the Automated Validation of Internet Security Protocols and Applications (AVISPA) toolkit.

The Challenge of Redefining the Imprisoned Self as an Artist: The Pedagogical Rituals of a Prison Arts Instructor

AbstractWhile some advocate the use of arts programmes to help improve inmates’ lives and reduce recidivism, the process of how such programmes can have therapeutic and practical value in prison's hostile environs requires further study. This project investigates how one prison arts instructor approaches the task of developing the inmates’ creative potential and unleashing their ‘inner artist’. The article describes the pedagogical approach aimed at helping prison inmates redefine themselves as artists via art classroom rituals. The imprisoned self as the artist, however, emerges mainly as a temporary identity that must be submerged upon return to the daily routines of hypermasculine prison environments. Thus inmates experience a profound duality of their identities, split between ‘artist’ and ‘inmate’, which constrains the long‐term therapeutic and rehabilitative value of the intervention.

Being and becoming a “good” qualitative researcher? Liminality and the risk of limbo

PurposeThe purpose of this paper is to re-conceptualise “good” qualitative research by discussing the intersection between “good” qualitative research and different identity states of “good” qualitative researcher. It uses the anthropological concept of liminality and related concept of limbo to help illustrate the implications of this intersection.Design/methodology/approachA reflexive and personal confessional account is provided of the author’s “living in” the liminal transition of the identity states from full-time PhD student to full-time early career researcher, questioning the author’s experiences in relation to others and the implications for the social construction of “good” qualitative research.Findings“Good” qualitative research is not just what to do but how to be. “PhD student” is a defined and temporary transitional liminal identity state. It has a clear point of separation (acceptance and registration of student status) and aggregation (“good” qualitative research signed of through thesis and viva). Contrasting with this is the “early career researcher” identity state, any point of aggregation towards “established researcher” is predicated on the unpredictability of publication and delivering impact indicators.Originality/valueThe paper demonstrates unsettling and in-betweenness of “good” qualitative research intersecting with the experience and composition of being a “good” qualitative researcher in the academy. It is important for debates regarding the qualities of academic development from PhD student to established researcher.

An efficient RFID anonymous batch authentication protocol based on group signature

In order to address the anonymous batch authentication problem of a legal reader to many tags in RFID (Radio Frequency Identification) system, an efficient RFID anonymous batch authentication protocol was proposed based on group signature. The anonymous batch authentications of reader to many tags are achieved by using a one-time group signature based on Hash function; the authentication of the tag to the reader is realized by employing MAC (Message Authentication Code). The tag's anonymity is achieved via the dynamic TID (Temporary Identity) instead of the tag's identity. The proposed protocol can resist replay attacks by using random number. Theoretical analyses show that, the proposed protocol reaches the expected security goals. Compared with the protocol proposed by Liu, the proposed protocol reduces the computation and storage of the server and tag while improving the security.

The impact of consumer's local-global identity on the evaluation of global versus local product

This study examines the effect of consumers’ local-global identity (chronical and temporary identity) on the evaluation of global products versus local products. Through two studies, the authors found that consumers with chronical local-global identity or temporary local-global identity tend to respond favorably to a product which consist with the salience or stimuli identity. Moreover, Study2 also found that consumers who perceive local and global identities as compatible (high bicultural identity integration BII) reinforce this effect, whereas consumers who perceive their identities as conflicting (low BII), this effect was reversed.
