LS-AKA: A lightweight and secure authentication and key agreement scheme for enhanced machine type communication devices in 5G smart environment

The 3rd Generation Partnership Project (3GPP) has implemented the Authentication and Key Agreement (AKA) protocol in 5G communication networks to ensure user equipment privacy. Due to the high density and concurrent communication, the primary goal is to provide an efficient authentication for massive enhanced Machine Type Communication (eMTC) devices. However, certain security flaws have been discovered in the 5G-AKA protocol, and no scheme has yet been developed that meets the needs of a group of eMTC devices, such as signaling congestion avoidance, key forward/backward secrecy (KFS/KBS) establishment, resistance against malicious attacks, and session key secrecy. Furthermore, the current group-based 5G communication network techniques do not require the group membership update mechanism at each device joining or leaving the group. To address these issues, we present a lightweight and secure technique for assembling a secure ecosystem of eMTC devices in a 5G network. The protocol employs the incremental hash mechanism to complete group member joining/leaving activities. For a thorough assessment of LS-AKA, the Random Oracle Model (ROM) is used to do formal security proofs, and informal security analysis shows that it is resistant to malicious attacks. In addition, the performance and simulation results of the existing and suggested protocols in terms of signaling, communication, and computing overhead are analyzed. According to the assessment results, the LS-AKA protocol improves the privacy and confidentiality of the 5G-enabled smart environment.

STRATEGI KOMUNIKASI RADIOGRAFER MELALUI MEDIA SOSIAL: STUDI PADA AKUN INSTAGRAM PERHIMPUNAN RADIOGRAFER INDONESIA (PARI)


 ABSTRACT
 BackBackground: The increasing number of social media users is currently being used by various sectors, including the health sector, which since the Covid-19 pandemic has received special attention from the public as ammunition for credible information. One of them is the Radiotherapy unit through various associations and or communities as an adhesive between radiographers. So far, Radioteapi has become a health unit that is safe in disseminating content information, no viral content has been found that contains negative content or violates the rules until it is in the name of the medical personnel in the Radiotherapy unit. This is certainly an opportunity to be used as a mediation of information in the health sector, especially through the association of medical personnel, one of which in this case is PARI. So, in the future, social media will not be limited only to the interests of members or radiographers but can be used as a manifestation of the radiographer's effective communication competence for the community.
 Methods: The research was conducted using a descriptive quantitative-qualitative approach with data collection methods in the form of literature studies, analysis of Instagram social media content, and interviews with PARI members. Convinience sampling was used to take samples of 2 central PARI Instragam accounts and 9 branch PARI Instagram accounts which were then processed by calculating engagement rate impressions and content strategy analysis with indicators like, comments and message content.
 Results: The results show that several central PARI Instagram accounts and branch managers have quite low engagement rate impressions, this can be improved by consistent content updates by considering the content strategy in the form of MEME content as entertainment as well as informative content, exposing members' experiences as positive reviews of the association, Documentation content of regular meeting activities and informative content of PARI membership updates.
 Conclusions: The content strategy that has been carried out at least meets the health indicators in the digital field according to a specific classification (Jean-Emmanuel Bibault, et all, 2017) in terms of reflective, responsive, relevant, and flexible information aimed at the target audience, namely between members and between radiographers. .

BP-MGKM: An efficient multi-group key management scheme based on bivariate polynomial

As wireless sensor networks are becoming increasingly reliant on communication among heterogeneous wireless sensor nodes , the need for secure communication in multi-groups has grown tremendously. Secure group key management in the multi-group scenario is a major challenge. The existing group key management schemes focus on managing a single group. However, there is not much work done regarding secure communication in multiple groups simultaneously. Existing multi-group key management schemes usually fail to meet the performance demands and suffer from improper management of keys, violation of security requirements, or huge complexity. We have analyzed the existing schemes for secure multi-group key management and found that the major issue lies in the complexity overhead during the membership update process in the multi-group scenario. On that account, we have proposed a new and efficient scheme (BP-MGKM) for secure multi-group key management based on bivariate polynomial . BP-MGKM is more efficient than other existing schemes in the context of complexity incurred during re-keying procedures. BP-MGKM features forward and backward secrecy, resilience against node compromise attack, collusion attack, and replay attack. The proposed scheme is secure and efficient than the existing schemes.

Dynamic Group Based Efficient Access Authentication and Key Agreement Protocol for MTC in LTE-A Networks

The machine-type communication (MTC) connects millions of the smart devices and provides a large number of applications through all of our lives. Every day, MTC is undergoing ubiquitous development and becoming a crucial application of the Internet of Things. To implement MTC in real-life, it is a big challenge to ensure the congestion control and security and privacy of the MTC devices (MTCDs) within the MTC network. When umpteen MTCDs concurrently try to access the network, each MTCD requires performing a distinct 3GPP specified access authentication procedure with the core network, that creates distressful signaling congestion over the MTC network. Taking into the consideration the aforementioned issues, in this research article, the authors suggest a dynamic group based access authentication and key agreement protocol for MTC called as EMTC-AKA protocol. The proposed protocol ensures strong mutual authentication between the MTC entities and identity protection of the MTCDs. Unlike, the other approaches, projected approach ensures confidentiality and integrity of the user/control plane data transmitted over the wireless interface and optimizes the need of group key update on each group membership update. We formally verified the suggested protocol on Automated Validation of the Internet Security Protocols and Applications (AVISPA) tool. The verification results and theoretical analysis of the protocol signify that the suggested approach is safe from the multiple malicious attacks and ensures less bandwidth consumption, signaling overhead, transmission cost and transmission delay over the MTC network.

P.427 - Family impact and Health-Related Quality of Life (HRQoL) of parents and individuals with SMA

SMA is characterized by muscle weakness and wasting, and the need for respiratory support and extensive care as the disease progresses. Little is known about HRQoL in SMA; however it is assumed that increased dependency and disease progression leads to poorer QoL for individuals and families living with SMA. To assess HRQoL the Pediatric Quality of Life Inventory(PedsQL) 4.0 Generic Core Scales, and PedsQL 3.0 Neuromuscular Module(NM) were completed by parents of individuals with SMA <18 years and by adults ≥18years with SMA via the Cure SMA membership update survey. Scores on the PedsQL range from 0–100, with higher scores indicating better functioning. Parents completed the PedsQL Family Impact Module (FIM) to assess parent self-reported HRQoL and family impact. A total of 482 surveys from 456 different families representing 468 unique individuals with SMA were completed by interim data cut. Of the 468 individuals with SMA, 29% had Type 1, 38% Type 2, 29% Type 3. The PedsQL NM was completed by 209 parents. Overall total mean PedsQL NM scores was 50.7(SD 17.5), with the lowest scores in Type 1(mean 39.8), followed by Type 2(mean 51.2), and Type 3(mean 62.9). The PedsQL FIM was completed by 241 parents. Overall total mean FIM score was 54.9(SD 18.4), range 0–93.75. A significant difference (p < 0.01) was observed in overall total FIM score by increasing SMA Type (Type 1: mean 49.4, SD 18.0; Type 2: mean 55.2, SD 17.7; Type 3: mean 62.3, SD 18.3). The mean summary score on the parent HRQoL was 55.5 (SD 18.1), range 0–94.6, with a significant trend (p < 0.01) of increasing scores by increasing SMA type. This study sought to understand and assess HRQoL and family impact of SMA on parents/families of individuals with SMA and HRQoL in adults with SMA. Research on the impacts of SMA on parent HRQoL and family impact are important to advance disease burden understanding and highlights the importance of family and patient advocacy and support services.

Improving Energy Efficiency of Grouping Abstraction in Cyber Physical System

Cyber Physical System (CPS) integrates physical and cyber components for high performance, self-maintenance, selforganization, self-assembly, while the process must be dependable, safe, secure, and efficient in real-time. It supports heterogeneous devices, such as motes, PDAs, laptops, and actuators according to the applications’ requirements. This paper describes an improved grouping abstraction for Cyberphysical systems.This abstraction allows different applications to simultaneously use the same sensors and actuators. It facilitates feedback control mechanisms by dynamic membership update and requirements reconfiguration based on feedback from the current members. It is implemented in Java, which ensures easy and conciseness of programming. It facilitates in-network aggregation and local processing which improves the lifetime of the network. This is shown in result to reduce energy consumption for enhancing the lifetime of the network. It would be validated on the application of smart campus ,which takes care of three functions like classroom occupancy, attendance monitoring aand area access controlling and monitoring.

Bundle: A Group-Based Programming Abstraction for Cyber-Physical Systems

This paper describes a novel group-based programming abstraction called a “Bundle” for cyber-physical systems (CPS). Similar to other programming abstractions, a Bundle creates logical collections of sensing devices. However, previous abstractions were focused on wireless sensor networks (WSNs) and did not address key aspects of CPS. Bundles elevate the programming domain from a single WSN to complex systems of systems by allowing the programming of applications involving multiple CPSs that are controlled by different administrative domains and support mobility both within and across CPSs. Bundles can seamlessly group not only sensors, but also actuators which constitute an important part of CPS. They enable programming in a multiuser environment with fine grained access right control and conflict resolution mechanism. Bundles support heterogeneous devices, such as motes, PDAs, laptops, and actuators according to the applications' requirements. They allow different applications to simultaneously use the same sensors and actuators. Bundles facilitate feedback control mechanisms by dynamic membership update and requirements reconfiguration based on feedback from the current members. The Bundle abstraction is implemented in Java which ensures ease and conciseness of programming. We present the design and implementation details of Bundles as well as a performance evaluation using 32 applications written with Bundles. This set includes across-network applications that have sophisticated sensing and actuation logic, mobile nodes that are heterogeneous, and feedback control mechanisms. Each of these applications is programmed in less than 60 lines of code.

Direct adaptive fuzzy control with membership function tuning

In this paper, a direct self-structured adaptive fuzzy control is introduced for the class of nonlinear systems with unknown dynamic models. Control is accomplished by an adaptive fuzzy system with a fixed number of rules and adaptive membership functions. The reference signal and state errors are used to tune the membership functions and update them instantaneously. The Lyapunov synthesis method is also used to guarantee the stability of the closed loop system. The proposed control scheme is applied to an inverted pendulum and a magnetic levitation system, and its effectiveness is shown via simulation.

Barchas is holding three books describing the proceedings of research conferences held as part of the grant.Credit: Jack DouthittThe APA Board of Trustees spent its most recent meeting in Arlington, Va., looking to the future as well as dealing with the day-to-day concerns of the organization and its members.President-elect Nada Stotland, M.D., proposed the formation of three work groups, all of which were approved by the Board. They are expected to present their reports at the Board's October meeting.In an effort to better prepare psychiatrists to respond to patients“ in a changing legal and regulatory environment” in which nonpsychiatrists are trying to expand their scope of practice beyond their training, one work group was tasked with “reinforc[ing] the unique education, training, expertise, and skills of psychiatrists” so they can better help their patients.A second work group will study and make recommendations about some phases of APA's relationship with pharmaceutical and medical-device companies. It will work with Medical Director James H. Scully Jr., M.D., to identify the categories and amounts of monies APA and its subsidiaries receive from the pharmaceutical and other industries that offer products or services used in psychiatry. The work group will also “determine what direct and indirect financial consequences there would be from discontinuing each category; indicate how APA could adapt to the attendant change in revenue; and provide the Board with the elements of a five-year plan to end or diminish pharmaceutical revenue received by APA.”The third work group will “build upon the 2003 report [written by former APA president Steven Sharfstein, M.D.] 'a vision for the Mental Health System' and provide the Board with information about the pros and cons of major national health care systems, as a basis for.. .formulating an APA position or policy for which to advocate with the federal administration that will take office in january 2009.”Among other business before the Board were the following:Scully gave a membership update, pointing out that the increase in membership has continued the slow but steady upward trend that began several years ago after a period of declining membership. APA now has 38,615 members, he noted, an increase of about 400 from 2006.The Board voted to add Boston to the list of cities in which APA holds its annual meeting, now that the city is close to having the number of hotel rooms and amount of convention space APA requires for its huge meeting. A Boston meeting has been tentatively scheduled for 2020.The Board endorsed a recommendation from the Elections Committee to make explicit that candidates for APA office are prohibited from posting on their Web sites letters of support written by third parties.The Board approved a one-time emergency grant of $30,000 to be used by APA's Area Councils to support the cost of their meetings. Trustees charged the Finance and Budget Committee with determining how these funds are to be distributed among the councils and to report their conclusions back to the Board Executive Committee no later than May.Actions taken by the Board at its March meeting will be posted in the Members Corner of APA's Web site at<www.psych.org>.▪ ISSUES NewArchived

A hierarchical approach to position-based multicast for mobile ad-hoc networks

In this paper we present Scalable Position-Based Multicast (SPBM), a multicast routing protocol for ad-hoc networks. SPBM uses the geographic position of nodes to provide a highly scalable group membership scheme and to forward data packets in a way that is very robust to changes in the topology of the network. SPBM bases the forwarding decision on whether or not there are group members located in a given direction, allowing a hierarchical aggregation of membership information. The farther away a region is from an intermediate node, the higher the level of aggregation for this region should be. Because of aggregation, the overhead for group membership management scales logarithmically with the number of nodes and is independent of the number of multicast senders for a given multicast group. Furthermore, we show that group management overhead is bounded by a constant if the frequency of membership updates is scaled down with the aggregation level. This scaling of the update frequency is reasonable since the higher the level of aggregation is, the lower the number of membership changes for the aggregate will be. The performance of SPBM is investigated by means of simulation, including a comparison with ODMRP, and through mathematical analysis. We also describe an open source kernel implementation of SPBM that has been successfully deployed on hand-held computers.

New Online Profile Will Help Us Serve You, Our Patients Better

Back to table of contents Previous article Next article The Medical Director's DeskFull AccessNew Online Profile Will Help Us Serve You, Our Patients BetterJames H. Scully Jr., M.D.James H. Scully Jr.Search for more papers by this author, M.D.Published Online:19 May 2006https://doi.org/10.1176/pn.41.10.0004APA is pleased to introduce an easy online method for members to update their member profiles. This will help expand the reach of the Online APA Membership Directory and better serve the needs of our membership. It will increase APA's knowledge of its members, and the new detailed membership information will enhance preparedness in the event of future crises and for other key functions.The revised online profile update, which was scheduled to go live on May 8, is called the Membership Profile Update and will result in a more effective Online APA Membership Directory. By improving the ability to change contact, biographical, and professional practice information, the profile update will make it easier to contact other members, make dependable patient referrals, and make accurate information more easily accessible.The information obtained from the Membership Profile Update will be of great benefit to APA in times of national emergencies. In the days following last year's devastating series of hurricanes, APA was inundated with questions through phone calls and e-mails from members seeking information on how to help, where to get help, placing referrals, and other key information. APA united internally and with other organizations to provide this information to those who sought it. The Membership Profile Update will expand APA's ability to harness member resources in the event of a crisis by providing a way to identify members with experience in specific practice settings. For example, if there is a need to find a forensic psychiatrists in Boise, Idaho, APA will have the capability to locate one quickly.The objective of the profile update is to ensure that the demographic and practice profile data on APA members, including languages spoken and areas of expertise, are available to create a more comprehensive picture of our membership and the variety of professional skills we possess.The Membership Profile Update comprises four sections: contact information, educational and professional background, current practice and professional activities, and other pertinent information. Members can indicate whether they wish to list part or all of their member profile on the secure, Online APA Membership Directory.The membership update program can be accessed at<http://memprofupdate.psych.org>.The Membership Outreach Program, another exciting program offered through APA's Membership Department, was created to provide training and orientation to new district branch executives and staff on all aspects of membership-processing operations. In an effort to improve support offered to the district branches and state associations (DB/SAs), the program provides monthly training to various DB/SAs. This has resulted in the quick and accurate processing of all membership actions and better service to all current and new members.At the beginning of the year, APA offered members the opportunity to pay membership dues online, which has proved to be a great benefit. Since late January, almost 800 members have taken advantage of the new opportunity. In addition, since the beginning of the year, members have had the ability to pay dues through an automatic monthly payment plan in which a member's credit card is automatically charged a prorated amount of dues on a scheduled monthly basis. Approximately 460 members have opted in to the payment-plan program to date, compared with about 325 at the end of last year when the program was still a pilot test for early career psychiatrist members. These advances have helped reduce the administrative burden on staff members.Members can try out the new Membership Profile Update in the APA Member Center at this month's annual meeting in Toronto.APA strives to provide the highest level of service that consistently exceeds the expectations of our members. We continue to look for ways to improve your membership experience and welcome your comments and suggestions.▪James H. Scully Jr., M.D., is medical director and CEO of APA. ISSUES NewArchived

A practical key management scheme for access control in a user hierarchy

In a user hierarchy we say that a security class is subordinate to another security class if the former has a lower security privilege than the latter. To implement such a hierarchical structure, it is often desirable to allow the user of each security class to derive the keys of its subordinating classes. This problem has been extensively studied but the existing solutions have various drawbacks. In this paper, we present a practical solution to this problem, which is an efficient key management scheme that needs only a reasonable amount of extra storage. It is secure because illegal key derivations are prevented, and key replacements do not reveal information about the relationship between the old key and the new key. It is also very flexible in that it supports convenient topological changes and membership updates. Furthermore, it provides a solution to the ex-member problem, that has been ignored in many existing research works.
