Formally, a digital signature scheme is a triple of probabilistic polynomial time algorithms, (G, S, V), satisfying: G (key-generator) generates a public key (pk), and a corresponding private key (sk), on input 1 n, where n is the security parameter. S (signing) returns a tag, t, on the inputs: the private key (sk), and a string (x).
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. 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.g., eIDAS in the European Union, NIST-DSS in the USA or ...
3 June 1997. Third reading. 3 June 1997. Amended by. Digital Signature (Amendment) Act 2001 [Act A1121] Status: In force. The Digital Signature Act 1997 ( Malay: Akta Tandatangan Digital 1997 ), is a Malaysian law enacted to make provision for, and to regulate the use of, digital signatures and to provide for matters connected therewith.
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 ...
Technosignature or technomarker is any measurable property or effect that provides scientific evidence of past or present technology. [1] [2] Technosignatures are analogous to biosignatures, which signal the presence of life, whether intelligent or not. [1] [3] Some authors prefer to exclude radio transmissions from the definition, [4] but such ...
Ring signature. In cryptography, a ring signature is a type of digital signature that can be performed by any member of a set of users that each have keys. Therefore, a message signed with a ring signature is endorsed by someone in a particular set of people. One of the security properties of a ring signature is that it should be ...
EdDSA. In public-key cryptography, Edwards-curve Digital Signature Algorithm ( EdDSA) is a digital signature scheme using a variant of Schnorr signature based on twisted Edwards curves. [ 1] It is designed to be faster than existing digital signature schemes without sacrificing security.
