Digital Signature<br />
Batch Verification<br />
◮ The term Digital Signature was coined by Diffie and Hellman (1976).<br />
◮ RSA was introduced at 1978.<br />
◮ Digital Signature helps us to achieve both Source Authentication<br />
and Data Integrity.<br />
◮ Digital Signature algorithms based on two popular pubic-key<br />
algorithms:<br />
◮ RSA signature scheme: based on the difficulty of factoring large<br />
composite integers.<br />
◮ ElGamal signature scheme: based on discrete logarithms problem.<br />
