Summary:Digital signature has been providing security services to secure electronic transaction over internet. Rivest, Shamir and Adlemen (RSA) algorithm was most widely used to provide security technique. Here we have modified the RSA algorithm to enhance its level of security. This paper presents a fair comparison between RSA and Modified RSA algorithm along with time and security by running several encryption and decryption setting to process data of different sizes. The efficiency of these algorithms was considered based on key generation speed and security level. The texts of different sizes were encrypted and decrypted using RSA and modified RSA algorithms. The simulation result proves that in Modified RSA algorithm key generation is faster and it enhances security by two levels. RSA algorithm is faster than Modified RSA in terms of encryption and decryption speed.
