A digital signature is a mathematical scheme for verifying the authenticity of digital messages or documents. A valid digital signature on a message gives a recipient ...
In cryptography, a Schnorr signature is a digital signature produced by the Schnorr signature algorithm that was described by Claus Schnorr. It is a digital signature scheme known for its simplicity, among the first whose security is based on the intractability of certain discrete logarithm problems. It is efficient and generates short ...
The ElGamal signature scheme is a digital signature scheme which is based on the difficulty of computing discrete logarithms. It was described by Taher Elgamal in 1985. [1] The ElGamal signature algorithm is rarely used in practice. A variant developed at the NSA and known as the Digital Signature Algorithm is much more widely used
The Digital Signature Algorithm (DSA) is a public-key cryptosystem and Federal Information Processing Standard for digital signatures, based on the mathematical concept of modular exponentiation and the discrete logarithm problem. In a public-key cryptosystem, a pair of private and public keys are created: data encrypted with either key can ...
[3] [4] [5] The Rabin signature scheme was the first digital signature scheme where forging a signature could be proven to be as hard as factoring. The trapdoor function was later repurposed in textbooks as an example of a public-key encryption scheme, [ 6 ] [ 7 ] [ 1 ] which came to be known as the Rabin cryptosystem even though Rabin never ...
It should only contain pages that are Digital signature schemes or lists of Digital signature schemes, as well as subcategories containing those things (themselves set categories). Topics about Digital signature schemes in general should be placed in relevant topic categories .
