in recent years, many security threats have entered into the organizations’ information and changed the  organizational performance resulting in their exorbitant costs. this question is of particular importanceabout government agencies that use information and internet systems. this issue enabled the top managers of organizations to implement a security system and minimize these costs. using in...

Industrial plants are heterogeneous networks with different computation and communication capabilities along with different security properties. The optimal operation of a plant requires a balance between communication capabilities and security features. A secure communication data flow with high latency and low bandwidth does not provide the required efficiency in a plant. Therefore, we focus ...

Security is the major area of concern in communication channel. Security is very crucial in wireless sensor networks which are deployed in remote environments. Adversary can disrupt the communication within multi hop sensor networks by launching the attack. The common attacks which disrupt the communication of nodes are packet dropping, packet modification, packet fake routing, badmouthing atta...

Communication security has become the keynote of the "e" world. Industries like eComm, eGov were built on the technology of computer networks. Those industries cannot afford security breaches. This paper presents a methodology of securing computer communication based on identifying typical communication behavior of each system user based on the dominant set of protocols utilized between the net...

Ensemble is a Group Communication System built at Cornell and the Hebrew Universities. It allows processes to create process groups in which scalable reliable fo-ordered multicast and point-to-point communication are supported. The system also supports other communication properties, such as multicast causal and total ordering, ow control, etc. This paper describes the security protocols and in...

We propose a new evaluation method for ‘generalized confidential modulation (GCM)’ for quantum communication. Confidential modulation realizes a secret communication by using secret information for modulation and noise in a channel. Y-00 is one of the famous methods of GCM for quantum communication. The existing evaluation methods for GCM are based on stream ciphers. They can estimate its analy...

Turbo codes enable reliable communication over powerconstrained 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 as Ad...
