A Parallel Method for RSA Cryptosystem Utilizing Topological Architecture


Users of today’s digital applications are increasing dramatically and there has been a rapid growth in the users of embedded wireless systems that usually transfer confidential information. These systems do expect robust, real time, and accurate performance, which bring Quality of Service (QoS) into mind. Parallel computing is one of the solutions to such issues to speed up the response time. On the other hand, cryptography is an important part and the first way of keeping information private. As a cryptography method, asymmetric encryption process needs massive mathematical operations, especially when a greater key is needed. This paper present a new parallel method for RSA cryptography based on mesh topology named MRSA. This method is applicable in embedded devices as a coprocessor and can act as a crypto-engine. The MRSA method is analyzed mathematically and compared to other methods. The result shows that the proposed method has fewer steps as well as multiplication operations to compute the encrypted value compared to the accepted method, which is the binary method.
