Secure information exchange

The rapid growth of electronic communication means that issues in information security are of increasing practical importance. Messages exchanged over worldwide publicly accessible computer networks must be kept confidential and protected against manipulation. Electronic business requires digital signatures that are valid in law, and secure payment protocols. Modern cryptography provides solutions to all these problems. This book originates from courses given for students in computer science at the Georg-Simon-Ohm University of Applied Sciences, Nurnberg.

When devices connecting to the Internet, one of the most problem occurred is security. There are many researchers focusing on this problem so far. Diffie-Hellman type key exchange protocols have a certain role in information security applications. This article proposes to perform encryption using pseudo-random strings to prevent unwanted attacks.

Methods for two distant parties to exchange their secret messages using single photons are considered. There existed several such methods but they are either insecure or face with information leakage problem. In this paper a new method to overcome the above-said limitations is proposed. The proposed method is also efficient because it also uses single photons in two degrees of freedom.

The foundational role of health information exchanges (HIEs) is to facilitate communication between clinical partners in real time. Once this infrastructure for the secure and immediate flow of patient information is built, however, HIEs can benefit community public health and clinical care in myriad other ways that are in line with their mission, goals, patient privacy, and funding structures.

Single Nucleotide Polymorphism (SNP) in the genome has become crucial information for clinical use. For example, the targeted cancer therapy is primarily based on the information which clinically important SNPs are detectable from the tumor. Many hospitals have developed their own panels that include clinically important SNPs. The genome information exchange between the patient and the hospital has become more popular.

The goal of this short paper is to provide evidence on how investment companies have changed the composition of their balance sheets across the recent financial crisis. For a large sample of United States brokers/dealers and asset managers, we analyze the information reported in the filings to the Securities and Exchange Commission (SEC). We observe that, the firms in the sample have shrunk the size of their assets through de-leveraging. The crisis though, has not induced firms to change substantially their financing structures.

Assessing growth determinants based on market benchmark, Stock market index is obtained from Stock Exchange of Thailand. Superior fund performance due to outstanding securities selection skills of fund managers come with higher price or higher management fees (Nazir and Nawaz (2010), Livingston and O’Neal (1998), and O’Neal (1999)).

Once an obscure subfield of finance, Market Microstructure has emerged as a major stream of finance. In its narrowest sense, microstructure might be defined as the study of the level and the source of transactions costs associated with trading. It examines the organizational structure of exchanges and how the specific market structure enhances the efficiency, transparency and information dissemination of security trading.

We focus on the dynamics of active management skills, and how an investor might optimally choose active funds during varying business conditions. Building on studies such as Avramov and Wermers (2006) and Moskowitz (2000), we allow for the possibility of time-varying mutual fund alphas and betas among active managers in Europe. Following Christopherson, et al. (1998) and Ferson and Schadt (1996), we model such time-variation using a publicly available set of conditioning state variables.
