Re: Patent status of SRP, SPEKE, etc.?

[Radia Perlman - Boston Center for Networking]

About SRP:

1) is it also royalty free for commercial use? I'd heard it
was for "noncommercial use"

2) even though RSP might be free, has anyone verified that SRP
doesn't infringe on EKE?

        I'm the inventor of SRP.  The version of the protocol described in RFC
        2945 (see http://srp.stanford.edu/) is royalty-free for worldwide use.
        
        David Jablon is the inventor of SPEKE.  Visit his website
        (http://www.integritysciences.com/) for licensing information.
        
        You should be able to contact the inventors of the other password
        protocols (AMP, PAK, S3P, SNAKE, etc.) through links on my site or David
        Jablon's site.
