Message Digest is the promising methodology of data integrity in the concerned areas of computer communication. Different techniques of message digest are available and used for checking the data integrity and indirectly used in digital signatures for authentication of the transmitted information. Several research papers are going on to make the computational process of message digest generation more complex to the unauthorized users. This paper introduces the procedure for generating message digest (Named as SGP-MD) using key in its algorithms so that the digest itself can directly act as a Message Authentication Code (MAC) and hence removing the need of separate encryption/decryption algorithm to create the MAC from the digest.
