A Lightweight Authentication and Key Sharing Protocol for Satellite Communication 一种用于卫星通信的轻量级认证和密钥共享协议
A. Murtaza, Tongge Xu, S. J. H. Pirzada, Jianwei Liu
Due to various critical aspects of information security, using Perfect Forward Secrecy (PFS) in many real-world communication applications is advantageous. Satellite communication is also among those applications where communication security is vital; hence, PFS is valuable. Security protocols are widely used to exchange session keys after authentication in many applications. However, the majority of existing security protocols use cryptographic algorithms (e.g., asymmetric/symmetric encryption and hash function to ensure the security of the protocol, which results in slow processing. Also, most of them require the exchange of several messages, which result in additional delay in communication and waste of bandwidth in terms of exchange of additional data. This paper presents a new authentication and key sharing protocol, which is much simpler and lighter hence faster than other protocols and still very secure because of having security comparable to that of theoretically secure One Time Pad.
由于信息安全的各种关键方面,在许多现实世界的通信应用中使用完全前向保密(PFS)是有利的。卫星通信也是通信安全至关重要的应用之一;因此,PFS是有价值的。在许多应用程序中,安全协议被广泛用于身份验证后的会话密钥交换。然而,现有的大多数安全协议使用加密算法(如非对称/对称加密和哈希函数)来确保协议的安全性,这导致处理速度缓慢。此外,它们中的大多数都需要交换多个消息,这会导致通信的额外延迟和交换额外数据方面的带宽浪费。本文提出了一种新的认证和密钥共享协议,该协议比其他协议更简单、更轻、更快,并且由于具有与理论上安全的One Time Pad相当的安全性,因此仍然非常安全。

Evaluation of OFDM-MIMO Systems Using Convolution with CPM 用CPM卷积评价OFDM-MIMO系统
Guowei Lei, Sunqing Su
Orthogonal frequency division multiplexing (OFDM) is regarded as a popular technique. Moreover, OFDM combined with multiple-input multiple-output systems (MIMO) has drawn many interests. However, OFDM-MIMO systems with continuous phase modulation have not been investigated extensively to date. In this paper, we propose an OFDM-MIMO system using convolution codes with continuous phase modulation (CPM). In the system, an interleaver is added between encoder and modulator. Moreover, iterative decoding and demodulation are combined together at receiver. To evaluate the performances, the comparisons between CPM and linear modulations in terms of bit error rate (BER), peak-to-average power ratio (PAPR) and power spectrum density (PSD) are given in the end.

Executive Function Evaluation System Based on Wiping Desk Behavior in Virtual Space 基于虚拟空间擦台行为的执行功能评价系统
Sho Ooi, Akihito Mihara, Mutsuo Sano, H. Tabuchi, F. Saito, S. Umeda
In this study, we report the development of a virtual reality (VR) system that evaluates executive function based on cleaning behaviors in real-time. It is known that patients with acquired brain injuries present adverse symptoms such as attention, memory, and functional disorders, as well as aphasia. Current methods to evaluate acquired brain injuries include tests such as the behavioral assessment of the dysexecutive syndrome (BADS) and digital clinical assessment for attention (D-CAT) tests; however, these tests require special/specific toolkits, and the methods are rigorous when applied for real-time dynamic evaluation. Moreover, patients are often burdened by the need to undergo paper tests as required by the evaluation methods. In this context, we propose and verify the efficacy of a method that offers real-time dynamic evaluation of acquired brain injury based on daily-living activities such as cooking, cleaning, and shopping. In this study, we focus on executive function relating to acquired brain injury, and we propose a real-time dynamic evaluation method for executive functioning using VR, which enables the automatic evaluation of subjects’ table-cleaning behavior. Our results indicate that our system can automatically assess subjects’ table cleaning behavior based on BADS test, while affording a cleaning behavior maximum average accuracy of 75.5%.
在这项研究中,我们报告了一个虚拟现实(VR)系统的开发,该系统基于实时的清洁行为来评估执行功能。众所周知,获得性脑损伤患者会出现不良症状,如注意力、记忆和功能障碍,以及失语。目前评估获得性脑损伤的方法包括执行障碍综合征(BADS)行为评估和数字临床注意力评估(D-CAT)测试;然而,这些测试需要特殊/特定的工具包,并且在应用于实时动态评估时,方法是严格的。此外,根据评估方法的要求,患者往往需要接受纸质检查,这给患者带来了负担。在此背景下,我们提出并验证了一种基于日常生活活动(如烹饪、清洁和购物)对获得性脑损伤进行实时动态评估的方法的有效性。在本研究中,我们关注与后天性脑损伤相关的执行功能,提出了一种基于VR的执行功能实时动态评估方法,该方法可以自动评估受试者的清洁桌子行为。结果表明,该系统可以基于BADS测试自动评估受试者的桌子清洁行为,同时提供清洁行为的最高平均准确率为75.5%。

The Array Microstrip Antenna for Mobile-Internet of Satellite Energy Communication 用于卫星能源通信移动互联网的阵列微带天线
M. Purnomo, V. Kusumasari, R. Hasanah, H. Suyono, A. Kitagawa
A simple Left-Handed Circularly Polarized (LHCP) proximity-fed equilateral-triangular array antenna with hole is proposed in order to support the mobile-internet of satellite energy communication covering the area of Japan (beam coverage elevation, El = 38° to 58°). In this paper, single-band LHCP triangular-patch array antenna is developed for receiver on ground applications. The targeted minimum gain of the antenna is set to 5 dBic at the central elevation angle (El = 48°), in Tokyo area, for applications using data-internet transfer of around hundreds kbps. The antenna consists of three equilateral-triangular patches with a hole for reception units operating at 2.50 GHz frequency bands. The antenna is simulated using the Method of Moments (MoM) analysis. The simulation results show that the frequency characteristics and the 3-dB axial ratio coverage in the conical-cut direction of the simulated antenna satisfy the target.

Study of the Interconnect Failure Mechanism and Micro-effort for ULSI ULSI互连失效机制及微努力研究
Q. Lin, Haifeng Wu
: Interconnect reliability has been regarded as a discipline that must be seriously taken into account from the early design phase of ultra large scale integration (ULSI). A synthetic review of valuable solutions to improve interconnect reliability is proposed in this paper. At first, a comprehensive review of the interconnect failure mechanisms and micro-efforts are carried out. Four types of interconnect failure mechanisms including EM, SM, TM and TDDB are illustrated in detail. Depending on their different effects for failure, the interconnect micro-effects are classified into the positive effects including the short-length effect, self-healing effect, reservoir effect and the negative effects which involves the skin effect, joule heating, current crowding , bandwidth, coupled noise, parasitic, RC delay, crosstalk and power dissipation and so on.

互连可靠性从超大规模集成电路(ULSI)的早期设计阶段就被视为必须认真考虑的一门学科。本文综合评述了提高互连可靠性的几种有价值的解决方案。首先,对互连失效机制和微观努力进行了全面的综述。详细阐述了EM、SM、TM和TDDB四种互连失效机制。根据其对失效的不同影响,将互连微效应分为短长度效应、自愈效应、储层效应等正效应和集肤效应、焦耳加热、电流拥挤、带宽、耦合噪声、寄生、RC延迟、串扰和功耗等负效应。其次,提出了一种新的基于雷达图的定性评价方法,直观地显示了与互连故障相关的关键性能的对比。这些结果可为集成电路互连可靠性的研究提供有价值的指导。

A synthetic review of valuable solutions to improve interconnect reliability is proposed in this paper. At first, a comprehensive review of the interconnect failure mechanisms and micro-efforts are carried out. Four types of interconnect failure mechanisms including EM, SM, TM and TDDB are illustrated in detail. Depending on their different effects for failure, the interconnect micro-effects are classified into the positive effects including the short-length effect, self-healing effect, reservoir effect and the negative effects which involves the skin effect, joule heating, current crowding , bandwidth, coupled noise, parasitic, RC delay, crosstalk and power dissipation and so on. Secondly, a novel qualitative evaluation method based on the radar chart has been presented, which visually shows the contrast of the key performance related to the interconnect failures. These present results might provide some valuable guidance for the study of IC interconnect reliability.","PeriodicalId":23787,"journal":{"name":"World Academy of Science, Engineering and Technology, International Journal of Electrical, Computer, Energetic, Electronic and Communication Engineering","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84570447","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
