Study of Various Cryptographic Algorithms

Cryptography is used to make secure data transmission over networks. The algorithm selected for cryptography should meet the conditions of authentication, confidentiality, integrity and non-repudiation. Cryptographic algorithms covered in this paper include AES, DES, RSA, Diffie-Hellman, RC4, Blow Fish, El-Gamal, MD5 and Miller-Rabin. Recent years have witnessed the phenomenal growth of RSA and most of the research in cryptography is done in the year 2010. The aim of this paper is to provide a study of the research work done in the cryptography field and various cryptographic algorithms being used, through a literature survey between the years 2008 and 2013. This paper represents the published knowledge from IEEE online database. 270 papers were concerned and after doing content filtering, 50 best suited papers were taken into consideration. Key word indices were used to identify the significant papers. This paper will provide a direction to the naive users and will allow many new future applications.
