Abstract
This paper proposes a new system of Substitution-Permutation network along with Randomization Expansion of 240 bits of input data. System uses 16 S-Boxes which are selected randomly based on the subkey values throughout 64 rounds of substitution steps. 64 sub-keys are generated during the SubstitutionPermutation process. The middletext is transposed based on decimal value of the sub-key generated during the each round. A CBC mode is the best associated with this system.
期刊介绍：
The paradigm for the next generation of information systems (ISs) will involve large numbers of ISs distributed over large, complex computer/communication networks. Such ISs will manage or have access to large amounts of information and computing services and will interoperate as required. These support individual or collaborative human work. Communication among component systems will be done using protocols that range from conventional ones to those based on distributed AI. We call such next generation ISs Cooperative Information Systems (CIS).
The International Journal of Cooperative Information Systems (IJCIS) addresses the intricacies of cooperative work in the framework of distributed interoperable information systems. It provides a forum for the presentation and dissemination of research covering all aspects of CIS design, requirements, functionality, implementation, deployment, and evolution.
