Study of RSA and Proposed Variant against Wiener's Attack

The paper discusses encryption schemes such as public key algorithms (RSA) and One Time Pads. It also discusses various attacks on the RSA algorithm. A brief introduction to Modular Arithmetic, which is the core arithmetic of almost all public key algorithms, has been given. In this paper we propose a variant to the RSA algorithm which is effective against Wiener’s Short Secret Exponent attack. The security and the efficiency of the proposed variant have also been discussed.
