A Survey on RSA Security Enhancement

Computer Engineering

The most common public key algorithm is RSA cryptosystem used for encryption and decryption. It is the first public key algorithm which provides security to transfer and saving of data over the network. In RSA cryptosystem there is less security and time of computation is still lengthy. This paper suggest a new algorithm concept to presents the modified form of RSA algorithm in order to speed up the implementation of RSA algorithm during data exchange across the network. This includes the architectural design and enhanced form of RSA algorithm through the use of third prime number in order to make a modulus n which is not easily decomposable by intruders. A database system is used to store the key parameters of RSA cryptosystem before it starts the algorithm. The proposed RSA method is compared with the original RSA method by some theoretical aspects. Comparative results provide better security with proposed algorithm.
