Abstract

Abstract- With growth of technology, the needs for data and information security over communication channels are necessary. One of the most important issues is the establishment of information security in marine communications. The RSA encryption algorithm is one of the most popular and most asymmetric algorithms used for secure data transfer. In the RSA encryption system, due to the very long key length, the encryption and decryption step speeds decrease, so it needs to improve its speed. One of the improving ways of RSA is RPrime RSA that includes the highest decryption of speed to RSA. In this paper, the encryption and decryption speed of RPrime RSA algorithm is improved using efficient residual number system. The result of implementation and comparison shows that the proposed method has an average of %22 and %36 improved at the encryption and decryption speed than the RPrime RSA algorithm.
