Pointcheval-Stern signature algorithm

Pointcheval–Stern signature algorithm

In cryptography, the Pointcheval–Stern signature algorithm is a digital signature scheme based on the closely related ElGamal signature scheme. It changes the ElGamal scheme slightly to produce an algorithm which has been proven secure in a strong sense against adaptive chosen-message attacks, assuming the discrete logarithm problem is intractable in a strong sense.

Schnorr signature

DIGITAL SIGNATURE SCHEME

Schnorr identification scheme; Schnorr signature algorithm

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.

Metric signature

MATHEMATICAL CONCEPT

Signature change; Signature (physics); Euclidean signature; +---; -+++; Lorentz signature; Mostly Plus; Mostly Minus; Signature of the metric

In mathematics, the signature of a metric tensor g (or equivalently, a real quadratic form thought of as a real symmetric bilinear form on a finite-dimensional vector space) is the number (counted with multiplicity) of positive, negative and zero eigenvalues of the real symmetric matrix of the metric tensor with respect to a basis. In relativistic physics, the v represents the time or virtual dimension, and the p for the space and physical dimension.

David Pointcheval and Jacques Stern developed the forking lemma technique in constructing their proof for this algorithm. It has been used in other security investigations of various cryptographic algorithms.
