什么时候标准会成为非标准?也许,是在建议的Internet标准中采用独自的技术时。7月底,当RSA的S/MIME建议被IETF的关键人物断然拒绝时,PGP迅速采用其优点,并提出了基于Pretty Good Privacy上“可信任的Web”模型的安全E-mail的新指标建议,确保所认识的人签名的真实性。X.509认证标准,也叫OpenPGP,可以分层提供认证及其它可接受的标准。 When do standards become nonstandard? Probably when proprietary technology is used in the proposed Internet standards. In late July, when RSA’s S / MIME proposal was categorically rejected by the IETF’s key players, PGP quickly took advantage of it and proposed a new metric for secure E-mail based on Pretty Good Privacy’s “Trusted Web” model, Make sure the signatures of people you know are authentic. The X.509 certification standard, also called OpenPGP, provides certification and other acceptable standards in a hierarchical manner.
