ELLIPTIC CURVE CRYPTOGRAPHY BASED AUTHENTICATED KEY AGREEMENT WITH PRE-SHARED PASSWORD

Based on elliptic curve Diffie-Hellman algorithm, an Elliptic Curve Authenticated Key Agreement (ECAKA) protocol with pre-shared password is proposed. Its security relies on the Elliptic Curve Discrete Logarithm Problem (ECDLP). It provides identity authentication,key validation and perfect forward secrecy, and it can foil man-in-the-middle attacks.     

高效的动态安全组播密钥协商方案

组播提供了一种发送者可以同时发送信息到多个接收者的高效通信机制。设计高效的密钥协商方案是实现安全组播的主要环节。以双线性对为工具,本文提出了一个新的基于身份的动态安全组播密钥协商方案,并具体地分析了当新提出的密钥协商方案用于组播时,子组之间的通信过程,以及组成员动态变化时密钥的更新过程,结果表明该方案在降低计算和通信代价方面取得了较好的效果,且满足组播密钥协商的各种安全要求。

Coherence measures and their relation to fuzzy similarity and inconsistency in knowledge bases

Intuitively it seems that the coherence of information received from heterogeneous sources should be one factor in determining the reliability or truthfulness of the information, yet the concept of coherence is extremely difficult to define. This paper draws on recent work on probabilistic measures of coherence by investigating two measures with contrasting properties and then explores how this work relates to similarity of fuzzy sets and comparison of knowledge bases in cases where inconsistency is present. In each area contrasting measures are proposed analogous to the probabilistic case. In particular, concepts of fuzzy and logical independence are proposed and in each area it is found that sensitivity to the relevant concept of independence is a distinguishing feature between the contrasting measures. In the case of inconsistent knowledge bases, it is argued that it is important to take agreeing information and not just conflicting and total information into account when comparing two knowledge bases. One of the measures proposed achieves this and is shown to have a number of properties which enable it to overcome some problems encountered by other approaches.     

Professional mobility for psychologists is rapidly becoming a reality.

Professional mobility for psychologists has been a problem since states first passed psychology licensing laws because of relatively small but crucial variations in licensing requirements. Although the profession of psychology and the association of psychology regulatory bodies in the United States and Canada (i.e., the Association of State and Provincial Psychology Boards [ASPPB]) have recognized this problem for decades, little progress was made in resolving it. Recently, the ASPPB launched two different approaches to facilitating professional mobility: one to forge agreements between regulatory bodies to accept each other's licensees, and another to certify or endorse individual psychologists who meet ASPPB standards for licensure and therefore can be recommended to licensing boards for relicensure. The specific requirements of each of these programs and their success in addressing the professional mobility problem are described. (PsycINFO Database Record (c) 2010 APA, all rights reserved)

Optimal time byzantine agreement for t <n/8 with linear-messages

Summary.  This paper presents a Byzantine Agreement protocol with n=8t+1, optimal number of rounds (namely min{ f+2, t+1} where f is number of actual faults), and messages of linear size (namely m≦n+O(log n), where m stands for message size). All previous protocols that stop in optimal time and tolerate t=O(n) faults require messages of size at least O(n ²). The new protocol uses a novel technique called Reconstructed Traversal which is based on the Reconstruction Principle and on the Coordinated Traversal protocol.

The Story of Istanbul's Modernisation

Since reform started under Ottoman rule in the early 19th century, Istanbul has undergone a substantial period of modernisation that has spanned more than 150 years. İlhan Tekeli outlines the metropolis' enduring development, characterising Istanbul's transformation into a modern city into four distinct periods. It is a story that bridges the collapse of the Ottoman Empire and the reconstruction of the Turkish Republic as a nation-state, with the initial demise of the city in favour of Ankara; and continues with Istanbul regaining its status as a world city; as it evolves from a monstrous industrial city to an urban region and global centre.
