A Review of RSA Cryptosystems and Cryptographic Protocols

Abstract

The use of cryptography in information security over insecure open network in both the convectional, symmetric encryption and the public-key cryptography has witnessed tremendous developments over the years. No doubt, the  public-key cryptography is an established technology in terms of modern approach in information security despite the seemingly challenges it has. This paper gives an overview of the public-key cryptography with emphasis on the RSA algorithm. We examined public-key cryptography, reviewed RSA  cryptosystems and cryptographic scheme, and discusses some security issues and challenges of RSA. The objective of this work is to present holistic appraisal of the RSA cryptosystems.

Keywords Cryptography, Public-key Cryptosystems, RSA algorithm, Encryption, Decryption, Cryptographic Scheme.
