A. Lakshmi, M. Praveen Kumar, Amitkumar Mahadevan · SSRN Electronic Journal · 2016
In this paper a new method is proposed for generating digital signature based on SHA- 512 hash algorithm. This method uses a secret key and enjoys the benefits of the private key cryptography. Two SHA-512 modules are connected in parallel for generating two 512-bit temporary signatures, signatures are permuted by the given secret key and generates 1024-bit signature. The efficiency of the algorithm is synthesized and verified using QUATRTUS II ALTERA by applying multiple scenarios.
