The growing sophistication of cyber attacks, vulnerabilities in highcomputing systems and increasing dependency on cryptography to protect ourdigital data make it more important to keep secret keys safe and secure. Fewmajor issues on secret keys like incorrect use of keys, inappropriate storageof keys, inadequate protection of keys, insecure movement of keys, lack ofaudit logging, insider threats and non-destruction of keys can compromise thewhole security system dangerously. In this article, we have proposed andimplemented an isolated secret key memory which can log life cycle of secretkeys cryptographically using blockchain (BC) technology. We have alsoimplemented a special custom bus interconnect which receives custom cryptoinstruction from Processing Element (PE). During the execution of cryptoinstructions, the architecture assures that secret key will never come in theprocessor area and the movement of secret keys to various crypto core isrecorded cryptographically after the proper authentication process controlledby proposed hardware based BC. To the best of our knowledge, this is the firstwork which uses blockchain based solution to address the issues of the lifecycle of the secret keys in hardware platform. The additional cost of resourceusage and timing complexity we spent to implement the proposed idea is verynominal. We have used Xilinx Vivado EDA tool and Artix 7 FPGA board.
