Аннотация

In this paper, the security of Selective Encryptionin RSA based Singular Cubic Curve with Automatic Variable Key (AVK) for some well known attacks are analysed. It is proved that this cryptosystem is more secure than Koyama scheme from which the algorithm has been generated. The proposed cryptographic algorithm makes justified use of Koyama Schemes. Koyama scheme is not semantically secure. The proposed Scheme is efficient and semantically secure public key cryptosystem based on Singular Cubic Curve with AVK. Further, the partially known attacks, linearly related plain text attacks, isomorphism attacks, low exponent attacks, Wiener’s attack and Hastad’s attack are analyzed for effect with the proposed scheme. The Selective Encryption in RSA based Singular Cubic Curve with AVK for text based documents is found to be robust enough to encounter all these attacks.
