Digital Signatures

From CryptoDox, The Online Encyclopedia on Cryptography and Information Security

Digital signature is a type of method for authenticating digital information analogous to ordinary physical signatures on paper, but implemented using techniques from the field of Public-key Cryptography. A digital signature method generally defines two complementary algorithms, one for signing and the other for verification, and the output of the signing process is also called a digital signature.

Algorithms

• Full Domain Hash, RSA-PSS etc., based on RSA
• DSA
• ECDSA
• ElGamal signature scheme
