Abstract

Information security is essential for today s world because of the newlineproliferation of computers and their ability to constitute the networks in the newlinefields of energy medicine space military banking transportation etc newlineMessages exchanged over worldwide publicly accessible computer networks newlinemust be kept confidential and protected against manipulation Cryptography newlineprovides solution to these problems newlineCryptography is the science of secret writing It involves the study newlineand applications of the principles and techniques which are used to secure the newlinedata flow between computers to digitize speech and to encrypt facsimile newlinemessages One of the major contributions of modern cryptography is the newlinedevelopment of advanced protocols providing high level cryptographic newlineservices such as secured user identification voting schemes and digital newlinecash The objective of the thesis is to analyze the cryptographic algorithms in newlineend to end communication and group oriented communications satisfying the newlinesecurity aspects and the cryptographic protocols in electronic voting newlineThere are numerous approaches to provide the cryptographic goals newlineConfidentiality authentication data integrity and non repudiation ranging newlinefrom physical protection to mathematical algorithms newline newline newline newline
