Station-to-Station protocol (original) (raw)
Il protocollo Station-to-Station (STS) è un protocollo crittografico per lo scambio di chiavi con autenticazione (authenticated key exchange, AKE). È una variante dello scambio di chiavi Diffie-Hellman, il quale è debole contro un attacco del tipo man-in-the-middle, dove un terzo utente si interpone nella conversazione e finge di essere il rispettivo interlocutore con entrambi i soggetti. Ideato da Whitfield Diffie, e Michael J. Wiener, il protocollo venne originariamente presentato al 1987 International Switching Symposium (ISS87) e successivamente pubblicato in nel 1992. Questo metodo fornisce autenticazione tramite l'uso di firma digitale e certificati digitali.

| dbo:abstract | In public-key cryptography, the Station-to-Station (STS) protocol is a cryptographic key agreement scheme. The protocol is based on classic Diffie–Hellman, and provides mutual key and entity authentication. Unlike the classic Diffie–Hellman, which is not secure against a man-in-the-middle attack, this protocol assumes that the parties have signature keys, which are used to sign messages, thereby providing security against man-in-the-middle attacks. In addition to protecting the established key from an attacker, the STS protocol uses no timestamps and provides perfect forward secrecy. It also entails two-way explicit key confirmation, making it an authenticated key agreement with key confirmation (AKC) protocol. STS was originally presented in 1987 in the context of ISDN security, finalized in 1989 and generally presented by Whitfield Diffie, Paul C. van Oorschot and Michael J. Wiener in 1992. The historical context for the protocol is also discussed in .

Station-to-Station protocol, STS) — криптографический протокол, позволяющий двум сторонам получить общий секретный ключ, используя незащищённый от прослушивания канал связи. Полученный ключ используется для дальнейшего обмена с помощью симметричного шифрования. В основе протокола лежит алгоритм Диффи-Хеллмана. Отличительной чертой STS протокола является отсутствие временных меток и поддержка свойства perfect forward secrecy. Также в протоколе проводится двухстороннее подтверждение ключа, что позволяет отнести протокол к классу «authenticated key agreement with key confirmation» (AKC). (ru) |
