ASH-512: Design and implementation of cryptographic hash algorithm using co-ordinate geometry concepts

Sending and receiving information over the internet is easy, fast and cost effective due to development of information technology. These days most of the information either personal or official is communicated through internet only. Most of the paper based documents are replaced by e-documents. So, there is a need to protect confidential or sensitive information in the computer as well as during transmission. Message digest is a mechanism, which is used to ensure message authentication and integrity. ‘Algorithm for Secure Hashing-512’ (ASH-512) is a novel algorithm proposed in this paper, which is designed using co-ordinate geometric concepts. The algorithm accepts 1024-bits as input and produces 512-bits as output. The algorithm is more secure and easy to construct and thus made this algorithm special. The algorithm is implemented in Java and the results are compared with standard cryptographic hash algorithm-SHA2 (512) and Whirlpool-512.
