What is Station-to-Station protocol?
The '''Station-to-Station (STS) protocol''' is a [[cryptography|cryptographic]] (information-hiding) [[key agreement]] scheme based on the classic [[Diffie-Hellman key exchange]] that provides mutual key and entity (party) authentication. In addition to protecting the established key from an attacker, the '''STS''' protocol uses no [[timestamp]]s and provides [[perfect forward secrecy]]. It also requires two-way explicit key confirmation, making it an ''Authenticated key agreement with Key Confirmation'' ([[Acronym]]: AKC) protocol. STS was originally presented in 1987 in the context of ISDN security {{Harv|O'Higgins|Diffie|Strawczynski|do Hoog|1987}}, finalized in 1989 and generally presented by [[Whitfield Diffie]], [[Paul van Oorschot|Paul C. van Oorschot]] and Michael J. Wiener in 1992. {{Math-stub}} [[Category:Cryptography]]
