2. Schnorr signature - Wikipedia

   en.wikipedia.org/wiki/Schnorr_signature

   Schnorr signature. 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.

3. ElGamal signature scheme - Wikipedia

   en.wikipedia.org/wiki/ElGamal_signature_scheme

   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.

4. Digital signature - Wikipedia

   en.wikipedia.org/wiki/Digital_signature

   Definition. A digital signature scheme typically consists of three algorithms: A key generation algorithm that selects a private key uniformly at random from a set of possible private keys. The algorithm outputs the private key and a corresponding public key. A signing algorithm that, given a message and a private key, produces a signature.

5. Digital Signature Algorithm - Wikipedia

   en.wikipedia.org/wiki/Digital_Signature_Algorithm

   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, two keys are generated: data can only be encrypted with the public key and encrypted ...

6. Blind signature - Wikipedia

   en.wikipedia.org/wiki/Blind_signature

   Blind signature. In cryptography a blind signature, as introduced by David Chaum, [ 1] is a form of digital signature in which the content of a message is disguised ( blinded) before it is signed. The resulting blind signature can be publicly verified against the original, unblinded message in the manner of a regular digital signature.

7. Elliptic-curve cryptography - Wikipedia

   en.wikipedia.org/wiki/Elliptic-curve_cryptography

   Elliptic-curve cryptography (ECC) is an approach to public-key cryptography based on the algebraic structure of elliptic curves over finite fields.ECC allows smaller keys to provide equivalent security, compared to cryptosystems based on modular exponentiation in Galois fields, such as the RSA cryptosystem and ElGamal cryptosystem.
