The Digital Signature Standard (DSS) is a Federal Information Processing Standard specifying a suite of algorithms that can be used to generate digital signatures established by the U.S. National Institute of Standards and Technology (NIST) in 1994. Five revisions to the initial specification have been released: FIPS 186-1 in 1998, [1] FIPS 186 ...
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.
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 ...
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 ...
DigiDoc ( Digital Document) is a family of digital signature - and cryptographic computing file formats utilizing a public key infrastructure. It currently has three generations of sub formats, DDOC - , a later binary based BDOC and currently used ASiC-E format that is supposed to replace the previous generation formats.
In cryptography, the Rabin signature algorithm is a method of digital signature originally proposed by Michael O. Rabin in 1978. [1] [2] [3] The Rabin signature algorithm was one of the first digital signature schemes proposed. By introducing the use of hashing as an essential step in signing, it was the first design to meet what is now the ...
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 advanced electronic signature is one of the standards outlined in eIDAS. For an electronic signature to be considered as advanced it must meet several requirements: [ 3][ 4] The signatory can be uniquely identified and linked to the signature. The signatory must have sole control of the signature creation data (typically a private key) that ...
