Techniques for secure distributed systems

Abstract

In recent networked world, more of the times computers work not isolation. They work with each other in order to satisfy communication purpose, processing, transfer of data, saving, etc., the systems can be described as distributed when it contain several systems work together in harmonic way with each other that are geographically lies over far distance. The security of distributed systems is very important issues and it may be describe as the most difficult part in the design for a system. In this paper the basic principles of distributed system is presented, then the security vulnerabilities are shown and the recent technique that used for solving the security problems are discussed and also analysis for their performance is done where the advantages and disadvantages with robustness for each technique are shown. So as conclusion for the results that are gotten by researchers, the selection of security technique depends on what really need to be protected, type of distributed systems and available resources. Although there are several efficient techniques, but the most powerful one is using of biometric and encryption for authentication and security purposes.
