The most famous digital signature assymetric algorithm
(DSA) A public key algorithm specified by Digital Signature Standard (DSS). DSA is only used to generate digital signatures. It cannot be used for data encryption.
The asymmetric algorithm that is at the core of the digital signature standard.
A FIPS-approved cryptographic algorithm specified by the Digital Signature Standard (DSS), FIPS PUBS 186. DSA is a standard algorithm used to create digital signatures. For detailed information, see http://www.itl.nist.gov/div897/pubs/fip186.htm.
The signing-only public key algorithm used in the Digital Signature Standard. DSA is a variant of the Elgamal (q.v.) algorithm.
A public key method only used for digital signatures. DSA's private key encryption provides authentication, integrity and non-repudiation but cannot be used for confidentiality. Although a modified DSA can support public key encryption, this feature is complex and very seldom used.
A public key algorithm developed by the federal government as part of the Digital Signature Standard for authenticating electronic messages.
The Digital Signature Algorithm (DSA) is a United States Federal Government standard or FIPS for digital signatures. It was proposed by the National Institute of Standards and Technology (NIST) in August 1991 for use in their Digital Signature Standard (DSS), specified in FIPS 186 http://www.itl.nist.gov/fipspubs/fip186.htm, adopted in 1993. A minor revision was issued in 1996 as FIPS 186-1 http://www.mozilla.org/projects/security/pki/nss/fips1861.pdf, and the standard was expanded further in 2000 as FIPS 186-2 http://csrc.nist.gov/publications/fips/fips186-2/fips186-2-change1.pdf.
