High-security pipelined elastic Substitution Box with embedded permutation facility

Abstract

In today’s world a major percentage of information and resource sharing is carried out through electronic means. A good portion of the above said activities needs security essentially. Since all the resources for any technology is provided by the nature, directly or indirectly, it is the moral responsibility entrusted with researchers to bring out maximum efficiency with minimal resources. In this paper a novel method is proposed in which Substitution Box is operated in a pipelined fashion, which can optimize hardware complexity and speed of the Block Ciphers. Facility for key-based permutation of message bits is integrated with the design, which offers additional security. The complexity and security analysis is also done.
