THE REPRESENTATION OF DASEIN S AWARENESS OF DEATH IN LOUIS DE BERNIÉRES NOVEL BIRDS WITHOUT WINGS

Throughout the human history, people have searched the ways of being different and unique. This quest has shaped various literary representations of uniqueness and especially in the postmodern period this concern gains more ground. Particularly, Heidegger’s theory of Dasein becomes most appealing, as Dasein’s difference and uniqueness emerges with his awareness. His level of awareness determines his status among ordinary people. His decisions and behaviours prepare him to become Dasein. The switch from everyday mode to authentic mode takes place through questioning. Authentic mode brings another level of awareness which establishes Dasein’s difference and characteristics. His awareness brightens his difference even in most terrific, outrageous situations such as the experience of death. This study focuses on Louis de Bernieres’ novel Birds Without Wings which depicts death as the most personal, unique and traumatic experience in one’s life. The novelist reveals how this trauma, experienced by his characters, leads to great suffering and pain. Using Heidegger’s perspective, Louis de Bernieres depicts Dasein’s difference during this experience. His awareness of his fragmentariness and his acknowledgement of his loneliness in this universe thwart the attempt to complete himself. This fragmentariness makes him Dasein. It is the reason that he accepts and embraces death of others. On another level, he embraces his own death, death of the self. This study considers mostly Georgio P. Theodorou from Birds Without Wings, a character who is beyond limitations as a Dasein, as he grasps the meaning of death and makes the readers aware of his dying process. His awareness of nothingness comforts him in the process of dying and allows him to be conscious during this process.

Mobile terminal identity authentication system based on behavioral characteristics

We propose a new type of authentication system based on behavioral characteristics for smartphone users. With the sensor and touch screen data in the smartphone, the combination of the motion state detection mode and the authentication mode can effectively distinguish between legitimate smartphone users and other users. The system deploys software on the smartphone to collect data from sensors and touch screens, and upload the data to the cloud. We apply random forest algorithm on the data to extract features and achieve motion state detection. Multilayer perceptron algorithm is used for user authentication in corresponding motion state. The system effectively implements an implicit and continuous authentication mode, which can achieve user identity authentication without users’ being aware of it. The system proposed in this article can achieve 95.96% accuracy with false rejection rate of 2.55% and false acceptance rate of 6.94%.

Multi-Point Collaborative Authentication Method Based on User Image Intelligent Collection in the Internet of Things

With the increasing demand for intelligent services of the Internet of Things (IoT), its security issues have attracted widespread attention recently. Since most of the existing identity authentication policies are based on a single authentication mode, they are highly likely to cause problems such as illegal operation and stealing of sensor information. In order to meet the needs of increasing IoT users for the security management of intelligent services, a multi-point collaborative authentication method based on user image intelligent collection for the security problems faced by IoT in identity authentication is proposed in the paper. This method firstly collects the identity of the legal user through the intelligent collection technology and then realizes the identity authentication of the unidentified user through the collaborative authentication between the local domain management machine, the back-end image management machine, and the cloud server. Compared with the traditional single identity authentication method, our method uses three-party collaborative authentication to avoid the problem of sensor information stealing easily caused by a single authentication method, which makes the user’s identity authentication more secure and effective. The security analysis shows that the method is able to resist multiple attacks and prevent the sensor information from being illegally operated and stolen, protecting the security of the sensor information.

Scheme on Cross-Domain Identity Authentication Based on Group Signature for Cloud Computing

In the cloud computing, different cloud service providers are often in different trust domains. As the traditional identity authentication mode cannot be applied to the cloud computing, the cross-domain identity authentication mechanism is needed to solve the identity authentication problem in the cloud computing. In view of the security problems in cloud computing, a cross-domain identity authentication scheme based on group signature is proposed. This scheme introduces a group of cloud service providers and users who are located in different trust domains. Any member of the group can generate the signature on behalf of the whole group, making the user access the cloud service provider in the case of privacy security. At the same time, with traceability it can track illegal operation of illegal users. In addition, the scheme uses the Chinese Remainder Theorem to integrate the message, and it can control the length of the data in the calculation process, simplifying the calculation process. It also realizes the join and revocation of group members without changing the key of other legitimate group members, and the maintenance cost of authentication schemes is low. The results show that the scheme has the advantages of anonymity, anti-counterfeit, traceability, anti- joint attack and so on. It can not only realize tracking function under the condition of guaranteeing user’s privacy, but can also simplify the authentication calculation process to improve the efficiency of the cross domain identity authentication, and its performance is more suitable for large-scale cloud computing environment.

A thirst for the authentic: craft drinks producers and the narration of authenticity.

There is a long academic tradition which positions the desire for authenticity as emerging as a symptom of dissatisfactions with modernity. Most recently, this has involved consumption of products that are valued for being authentic in contrast to mass produced commodities which are seen as being homogeneous, standardized and therefore inauthentic. A recent resurgence in interest in the idea of craft and craftwork has brought to the fore concerns about re-establishing connections between products, consumers and producers beyond rational market exchange. This research draws on interviews with 40 craft brewery and distillery workers to explore the ways in which authenticity is narrated as part of an ongoing effort to add value to their products and the contexts of their production. The article identifies six modes of authenticity which are drawn on in combination by participants to establish a narrative of authenticity. This is understood to be a clear illustration of the 'enrichment process' by which post-industrial economies manufacture value. A central element of craft drink producers' work is the marshalling of cultural value and engaging in communicative and performative acts that ascribe that value to products and the people involved in making them.

Generalized Tweakable Even-Mansour Cipher and Its Applications

This paper describes a generalized tweakable blockcipher HPH (Hash-Permutation-Hash), which is based on a public random permutation P and a family of almost-XOR-universal hash functions $$ \mathcal{H}={\left\{ HK\right\}}_{K\in \mathcal{K}} $$ as a tweak and key schedule, and defined as y = HPHK((t1, t2), x) = P(x ⊕ HK(t1)) ⊕ HK(t2), where K is a key randomly chosen from a key space $$ \mathcal{K} $$ , (t1, t2) is a tweak chosen from a valid tweak space $$ \mathcal{T} $$ , x is a plaintext, and y is a ciphertext. We prove that HPH is a secure strong tweakable pseudorandom permutation (STPRP) by using H-coefficients technique. Then we focus on the security of HPH against multi-key and related-key attacks. We prove that HPH achieves both multi-key STPRP security and related-key STPRP security. HPH can be extended to wide applications. It can be directly applied to authentication and authenticated encryption modes. We apply HPH to PMAC1 and OPP, provide an improved authentication mode HPMAC and a new authenticated encryption mode OPH, and prove that the two modes achieve single-key security, multi-key security, and related-key security.

Moving beyond Goffman: the performativity of anonymity on SNS

PurposeThis paper aims to explore consumer behaviour on the popular anonymous social networking site (SNS) Yik Yak. It examines the reasons behind the turn to anonymous social networking and also considers the ways in which anonymity impacts consumers’ self-performances on SNS.Design/methodology/approachThe study used a netnographic approach to explore Yik Yak across eight universities in Ireland and the UK. Data are based on observation and participation on the app. Screenshots on smart phones were the central method used to collect data. Data also included 12 in-depth interviews.FindingsYoung consumers are becoming fatigued by the negative effects of self-presentation on many SNS. By enabling consumers to engage in what they consider to be more authentic modes of being and interaction, Yik Yak provides respite from these pressures. Through the structures of its design, Yik Yak enables consumers to realise self-authentication in anonymised self-performances that engender a sense of virtue and social connection.Practical implicationsThis research highlights the potential value of anonymous SNS in fostering supportive dialogue, concerning mental health amongst post-millennials.Originality/valueBy invoking a performative lens, this paper extends a novel theoretical approach to understandings of identity formation within consumer research. By highlighting anonymity as a dynamic process of socio-material enactments, the study reveals how consumers’ self-performances are brought into effect through the citation of various discursive arrangements, which promulgate distinct understandings of authenticity.

Naming and ordering the modes, in light of combinatorics on words

One of the most telling features of the application of combinatorics on words in mathematical music theory is the extent to which aspects of the history of theory are captured by the word theory model. Well-formed modes, including the usual diatonic modes, are modeled by Christoffel words and their conjugates. A class of Sturmian morphisms produces words representing the Glarean modes, and gives rise to standard factorizations, which in turn model the authentic and plagal divisions of the diatonic modes. The principal discussions are the renaming of the ancient Greek modes in the tenth-century Alia musica, and the reordering of the authentic modes of Glarean's Dodecachordon by Zarlino in 1571. The latter exemplifies a recently demonstrated property in combinatorics on words, the matching of the conjugation order with the lexicographic order for the conjugation class of a given special Sturmian morphism. The two main topics are unified in this presentation.

S L I SCP-light

The emerging areas in which highly resource constrained devices are interacting wirelessly to accomplish tasks have led manufacturers to embed communication systems in them. Tiny low-end devices such as sensor networks nodes and Radio Frequency Identification (RFID) tags are of particular importance due to their vulnerability to security attacks, which makes protecting their communication privacy and authenticity an essential matter. In this work, we present a lightweight do-it-all cryptographic design that offers the basic underlying functionalities to secure embedded communication systems in tiny devices. Specifically, we revisit the design approach of the sLiSCP family of lightweight cryptographic permutations, which was proposed in SAC 2017. sLiSCP is designed to be used in a unified duplex sponge construction to provide minimal overhead for multiple cryptographic functionalities within one hardware design. The design of sLiSCP follows a 4-subblock Type-2 Generalized Feistel-like Structure (GFS) with unkeyed round-reduced Simeck as the round function, which are extremely efficient building blocks in terms of their hardware area requirements. In S L I SCP-light, we tweak the GFS design and turn it into an elegant Partial Substitution-Permutation Network construction, which further reduces the hardware areas of the S L I SCP permutations by around 16% of their original values. The new design also enhances the bit diffusion and algebraic properties of the permutations and enables us to reduce the number of steps, thus achieving a better throughput in both the hashing and authentication modes. We perform a thorough security analysis of the new design with respect to its diffusion, differential and linear, and algebraic properties. For S L I SCP-light-192, we report parallel implementation hardware areas of 1,820 (respectively, 1,892)GE in CMOS 65 nm (respectively, 130 nm ) ASIC. The areas for S L I SCP-light-256 are 2,397 and 2,500GE in CMOS 65 nm and 130 nm ASIC, respectively. Overall, the unified duplex sponge mode of S L I SCP-light-192, which provides (authenticated) encryption and hashing functionalities, satisfies the area (1,958GE), power (3.97μ W ), and throughput (44.4kbps) requirements of passive RFID tags.

Information Security Management: Password Security Issues

Abstract As users of technology in our everyday actions we need to authenticate in different applications, in fast and secure mode. Although passwords are called the least secure mode of authentication, it’s the simplicity of entering a textual password for just a few seconds, especially when a fast transaction is needed, the main advantage that textual password based authentication method has against other authentication methods. We have prepared a questionnaire that will help us to identify the practices, characteristics, and problems of creation and usage of passwords in online applications, services and social networks. The target population is a group of users who have knowledge on information technology in public administration.

The Authentic and Inauthentic Sport in the Hermeneutic and Phenomenological Perspectives

Summary The philosophical concept of hermeneutics presents the opposite pole of human mental activities than positivism. Phenomenology, together with hermeneutics, also presents a kind of opposition to the positivistic reduction of learning the world. This paper focuses on the topic of authenticity of sport from these two (hermeneutic and phenomenological) approaches. As a basic theoretical platform Martin Heidegger’s book Time and Being is used. The authors develop a specific kind of categorization of the social groups engaged in sport events via the ancient concepts of “TECHNÉ ATHLETIKÉ” and “TECHNÉ GYMNASTIKÉ”. Two different phenomena: sport and “sport” are examined within the next part of the paper. There are some reasons mentioned in conclusions coming from the hermeneutic and phenomenological approach which help us to understand and accept the opinion that a kind of return to “techné gymnastiké” can support the authentic modes of being in human approach to sport.

TWO PHASES AUTHENTICATION LEVEL (TPAL) PROTOCOL FOR NODES AUTHENTICATION IN INTERNET OF THINGS

Nodes are required to be authenticated in order for them to join the network nodes especially for Low power and Lossy Network (LLN). The purpose of authentication is to verify the claimant is really what it claims to be. Since LLN made up from many nodes, some of the node may contain sensitive informations such as military data and monitoring data. Therefore, any packets forwarded by a node may need authentication at the source and destination nodes. LLN is a kind of Internet of Things (IoT) network with limited power source due to the fact they running on battery, low processing capability, have high data loss and low data rate. Current authentication Internet protocols cannot be adopted directly into LLN due to its characteristics. For now, LLN rely on the authentication provided by Routing Protocol for LLN (RPL) which is based on symmetric cryptography. However, RPL specification stated thatany node that wants to act properly as a router by using the authenticated mode in RPL should not be based on symmetric cryptography. A two phase authentication level (TPAL) is proposed in this paper to improve the authentication mode used in RPL. The proposed protocol contains two parts mainly for system initialization and node authentication phase with the help from a trusted party. The authentication takes place during node discovery which is guided by the routing protocol thus only those nodes in the data path will be authenticated. Keywords: LLN, RPL, verification, ECC, lightweight, scheme

A Multiscale Autoregressive Model-Based Electrocardiogram Identification Method

With increasing security and privacy requirements, electrocardiogram (ECG)-based biometric human identification and authentication is gaining extensive attention. This paper aims to solve three major problems: stable identity feature is hard extracted from the inferior quality ECG, the performance of authentication system falls down when the size of registered sample set increases, and the authentication system needs to retrain when a new registered identity is added. To improve the robustness of identity feature, this paper proposed a multiscale feature extraction method using a multiscale autoregressive model (MSARM). First, the performance of multiscale feature was tested by simple matching method based on Chi-square distance in identification system. The test was performed on self-built SIAT-ECG and public PTB databases, which contain 146 and 100 (50 healthy volunteers and 50 patients with myocardial infarction) individuals, respectively. The recognition rate exceeded 93.15% for both databases in identification scenario. The results revealed that the MSARM has more excellent performance than other feature extraction methods. Then, this paper proposed a combination classifier method with one-to-one structure in authentication mode. It yielded a true rejection rate (TRR) of 98.99% and true acceptance rate (TAR) of 95.04% when registered sample set contains 140 individuals from SIAT-ECG database. Therefore, the proposed MSARM and combination classifier not only significantly improve the accuracy but also enhance the practicability of ECG-based biometric systems.

A new method for identity authentication using mobile terminals

Password and short message based authentication methods are currently the most popular ones to authenticate mobile users. However, there are many security risks involved in these authentication methods. This is because passwords are mostly static and SMS-based authentication codes are mostly transmitted in plaintext form and can thus be easily intercepted, making users identities easily exposed to adversaries [1]. In recent years, fingerprint identification and face recognition technologies have set off a huge tide in the identification and authentication of mobile terminals. However, some users may not have sufficient fingerprint characteristics while some other users may generate a great number of impressions by making some changes in the face. The visual image of the face can also vary greatly, not to mention that face recognition is affected by illumination conditions, areas of coverage, ages, etc., making facial recognition very unstable for authentication [2, 3]. In this paper, we propose a technique in which we use IMEI (International Mobile Equipment Identity) to apply the backstage hidden automatic identification authentication mode for the user. The proposed scheme has good user experience and can enhance the practicability of identity authentication. In addition, compared to existing authentication schemes, the proposed scheme does not require the transmission of sensitive data in the authentication process, further enhancing security.

Gainful game, set-up, cyberworld

There is a critique of capitalist market economy that consists in claiming not only that capitalist social relations are uncaring and alienating, nor only exploitative of the working class, but that the process of capitalist economy as a whole is a way of living, today globalized, that has gotten out of hand. Its essential nature is unmasked as a senseless circular movement that, besides ruthlessly exploiting natural resources, demeans human being itself and alienates it from the historical alternative of a purportedly authentic mode of human being rooted in collective, solidaric subjectivity. The present article offers an alternative hermeneutic cast for understanding capitalism as the gainful game that can serve as philosophical orientation in fighting for a free and fair social interplay in which the powers and abilities of free individuals are appropriately and reciprocally estimated and esteemed. This requires, first and foremost, seeing through the fetishisms inherent in the valorization of reified value that the mature Marx identified in his critiques of political economy as the essential nature of capitalism. Such critical insight is necessary for orientation also in today’s predicament of the ever more encroaching and ensnaring cyberworld.

P.3.b.009 - Cognitive effects of polypharmacy in psychotic disorders – less is more

Along with the development of user-centric wireless communications, wearable devices appear to be popular for real-time collecting a user’s private data to provide intelligent service support. Compared with traditional short-range communications, the wearable devices confront more severe system vulnerabilities and security threats during interactions. Considering the limitations of computational capabilities and communication resources, it brings more challenges to design privacy-preserving authentication schemes for the resource-constrained wearable devices. In this work, local authentication and remote authentication are respectively designed for cloud assisted wearable devices. In the local authentication mode, hash based selective disclosure mechanism and Chebyshev chaotic map are jointly applied to achieve mutual authentication between a wearable device and a smart phone. In the remote authentication mode, Merkle hash tree based selective disclosure mechanism is designed to improve the structure of data fields in the certificate, and a yoking-proof is established to realize interactions between two wearable devices and a smart phone, and is further transmitted to the cloud server for simultaneous verification. Meanwhile, security formal analysis is performed based on the BAN logic for proving that the proposed remote authentication protocol has theoretical design correctness. It indicates that the proposed authentication scheme is available and flexible for ubiquitous wearable devices.

Adoption problems? How UX could boost biometrics

If we believe the hype today, biometric and face recognition-based authentication are set to transform mobile and personal computers. Yet this is what media and tech companies have been saying ever since 2004 when IBM released a ThinkPad laptop that included a fingerprint reader. Biometrics was also the Next Big Thing in 2011 when Motorola introduced the Atrix, the first smartphone with fingerprint identification. This leads to a pretty big question for all of us in the security business: if biometric solutions are such amazing technologies, why weren't they widely adopted in the in the early 2000s – or why aren't they in widespread use now? Why are we still waiting for something as simple as fingerprint recognition (never mind retinal scans or face recognition) to become the default mode of authentication?

God changes people: modes of authentication in Evangelical conversion narratives

One of the distinguishing characteristics of Evangelicalism is the conversion story. In this article we focus on the conversion stories of interviewees within the setting of several related Evangelical television programs broadcast in the Netherlands since the 1980s. We argue that the conversion story is construed through a particular view on and practice of authenticity. Thus we see that, in the televised conversion story, modes of authentication are at work in what we analytically distinguish as frames, narratives, and strategies of authentication. We argue that the idea of an authentic transformation has changed from a more fundamentalist mode of authentication, emphasizing the subjection of the self to a particular religious narrative, to a more expressive mode of authentication that emphasizes the exploration of the inner, unique self of the interviewee.
