Digital Signature Standard

(cryptography, standard)
The NIST's standard for digital signatures (authenticating both a message and the signer) that was first announced in 1991. It is based on an algorithm using discrete logarithms, which is a variant of the Elgamal algorithm with Schnorr's improvements. DSS's security is currently considered very strong - comparable to RSA. It is estimated that DSS's 1024-bit keys would take 1.4E16 MIPS-years to crack.

RSA Data Security's Technology Marketing Manager Kurt Stammberger says the government's search for an alternative to RSA as a digital signature standard is based on its concern that users would then find it cheap and easy to use RSA's related encryption software, based on the same algorithm.
Freedom of Information Act more than two decades ago show that tensions over security software arose in the early 1990s between the NSA and other scientists in the government who had been working together since 1989 to develop the Digital Signature Standard, a way to electronically sign documents and guarantee their authenticity.
The Digital Signature Standard is on the base of many current research topics today, like signcryption.
Last month, after nearly 3 years of debate, the National Institute of Standards and Technology in Gaithersburg, Md., announced the approval of the Digital Signature Standard (DSS), which performs a similar function for electronic messages and data (SN: 9/7/91, p.148).
On August 30, 1991, the National Institute of Standards and Technology (NIST) proposed a Digital Signature Standard (DSS) that specifies a Digital Signature Algorithm (DSA) appropriate for applications requiring a digital rather than written signature.
It was clear the proposed digital signature standard (DSS) had not garnered many fans.
Now the National Institute of Standards and Technology (NIST) in Gaithersburg, Md., has issued a proposal for a digital signature standard, which allows recipients of electronically transmitted information to verify the sender's identity and the data's integrity.
Government agency NIST has recently proposed a public key digital signature standard [3, 4].
