AbFab is defining a GSS EAP mechanism that can encapsulate the EAP methods you mention. This mechanism could be run over SASL-TLS using GS2. Josh. --- original message --- From: "Yaron Sheffer" <yaronf.ietf@gmail.com> Subject: Re: [kitten] [saag] HTTP authentication: the next generation Date: 12th December 2010 Time: 7:36:41 am Hi Luke, I am not a big fan of EAP myself (although I am a co-author on Yoav's TLS-EAP), but no, for pragmatic reasons SASL is not the moral equivalent. There is a number of EAP methods that provide zero-knowledge password based mutual authentication (i.e. password based auth that's *not* susceptible to dictionary attacks). These include (see http://www.iana.org/assignments/eap-numbers/eap-numbers.xml#eap-numbers-3) EAP-SRP-SHA1, EAP-pwd, EAP-EKE and EAP-SPEKE. As far as I can see (http://www.iana.org/assignments/sasl-mechanisms/sasl-mechanisms.xhtml) SASL does not provide any equivalent method.
