Improvement in Message Authentication Algorithm using TLS1.0

The main focus of this project is to enhance the data integrity in next generation encryption using TLS1.0. Our aim is to remove the pre-existing vulnerabilities in the present SHA algorithm and make it more attack resistant. TLS 1.0 supports encryption, authentication and key exchange. This project presents an enhancement (SHA-176) in the authentication of the existing authentication algorithm (SHA-160). The current algorithm used in TLS for message authentication and data integrity is mainly Secure Hashing Algorithm (SHA). This project tries to enhance the current SHA-160 algorithm so as to make the algorithm more attack resistant. The current SHA algorithm uses a 160 bit message digest but is susceptible to certain attacks; it has helped in coming over the vulnerabilities of MD5 but has certain problems which have to be overcome. This project presents an enhancement in the algorithm by forming a 176 bit message digest thus increasing the size of the digest as compared to the original algorithm. The SHA-176 uses 11 chaining variables of 16 bit each consisting of 80 rounds. The proposed algorithm has proved to increase security for the hashing techniques so that the user feels safe while transmitting data over the transport layer. The hashing times differ by a small factor but we can still use the SHA-176 model in TLS 1.0 for Message authentication as the security in SHA-176 is more and it is a stronger algorithm as compared to SHA-160.
