Compact Lightweight Cryptographic Algorithmfor Optimizationof Resources

Abstract

The study of Lightweight cryptography has been one of the intresting topics in symmetric cryptography in the recent years. Lightweight symmetric ciphers has gained interest due to the increasing demand for security services in constrained computing environments, such as in the Internet of Things(IoT). Though the protocols of light weight in are providingingmore security in variousapplications,resource utility is more in key generation, key scheduling, permutation layer and substitution box layer operations. More resource usage make possibletohave highutilization of power andoverhead of area. In this paper, a novel method is proposed to decrease theutility of resoures, which followsregister reutilization scheme. The resource reutilization is coordinating with the delay inSubstitutionPermutation Network (SPN).Our design is compared, using area, throughput, power, and latency as metrics.
