Signature (logic) In logic, especially mathematical logic, a signature lists and describes the non-logical symbols of a formal language. In universal algebra, a signature lists the operations that characterize an algebraic structure. In model theory, signatures are used for both purposes.
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.
The discrete logarithm log 10 a is defined for any a in G. Powers of a fixed real number. A similar example holds for any non-zero real number b. The powers form a multiplicative subgroup G = {…, b −3, b −2, b −1, 1, b 1, b 2, b 3, …} of the non-zero real numbers. For any element a of G, one can compute log b a. Modular arithmetic
A signature block (often abbreviated as signature, sig block, sig file, .sig, dot sig, siggy, or just sig) is a personalized block of text automatically appended at the bottom of an email message, Usenet article, or forum post.
An electronic signature, or e-signature, is data that is logically associated with other data and which is used by the signatory to sign the associated data. [1] [2] [3] This type of signature has the same legal standing as a handwritten signature as long as it adheres to the requirements of the specific regulation under which it was created (e ...
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. DSA is a variant of the Schnorr and ElGamal signature schemes.
