There were e-mail and verbal proposals for asymmetric signatures on and off in the working roup from the begining. Hilarie has broght up this topic at many meetings ... So Ran, are you saying that you patented the use of asymmetric algorithms as IPsec security transforms (AH or ESP)?

To: Jeff Schiller, Security Area Director, IETF, <jis@mit.edu> From: Randall Atkinson, <rja@inet.org> Subject: Notification of patent I have just been officially notified that US Patent 5, 511, 122 on "Intermediate Network Authentication" was issued to me on 23 April 1996 with all rights assigned to The United States of America as represented by the Secretary of the Navy. The filing date on this patent is 3 June 1994 and the work was begun in 1991. The funded project work behind this patent was unrelated to IPsec and primarily related to a need for intermediate network authentication of datagrams in a network that performed intermediate fragmentation of datagrams. I am not a lawyer and I am not making any kind of legal representation, but I believe that this patent DOES NOT create any issues with respect to current IPsec RFCs or any current IPsec draft that I am aware of or any other IETF standard that I'm aware of. The patent might affect a (hypothetical) AH transform proposal that used cryptographic digital signatures based on asymmetric cryptography (e.g. an RSA digital signature), as distinguished from all current standards-track documents and online proposals (which I believe all use keyed one-way cryptographic hash functions). --
