Turbo codes enable reliable communication over power-constrained communication channels at close to Shannon's limit. Further, the performance of the communication system is enhanced by incorporating security mechanism. Security is described as the process of minimizing the vulnerabilities of assets or resources. National Institute of Standards and Technology (NIST) chose Rijndael algorithm...

Short-range wireless communication applications have become common nowadays. Healthcare systems based on them hold a remarkable promise for the costly treatment of chronic diseases. Healthcare applications utilize various wireless communication technologies in order to achieve a good connectivity, which is essential in ubiquitous computing. Weak security in wireless networks may ruin the securi...

BACKGROUND Video calls from mobile phones can improve communication during medical emergencies. Lay bystanders can be instructed and supervised by health professionals at Emergency Medical Communication Centers. Before implementation of video mobile calls in emergencies, issues of information security should be addressed. METHODS Information security was assessed for risk, based on the inform...

This chapter deals with the issues concerning e-mail communication security. We analyze the most popular security mechanisms and standards related to the e-mail communication and identify potential threats and vulnerabilities. The most significant drawback of all current approaches is the impossibility of keeping headers information authentic. This leads to possible impersonation attacks and pr...

Although electronic commerce is a relatively new concept, it has already become a normal aspect of our daily life. The software agent technology is also relatively new. In the area of electronic commerce, software agents could be used for example to search the lowest prices and the best services, to buy goods on behalf of a user, etc. These applications involve a number of security issues that ...

Some of the known results for delivering deterministic bounds on endto-end queuing delay in networks with constant packet sizes and constant link rates rely on the concept of Route Interference. Namely, it is required to know the number of ows joining on any output link in the whole network. In this paper we extend the existing results for the more generic cases of connection-oriented networks ...
