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).

B. Does this disclosure relate to an unpublished pending patent application?: NO
C. If an Internet-Draft or RFC includes multiple parts and it is not reasonably apparent which part of such Internet-Draft or RFC is alleged to be covered by the patent information disclosed in Section V(A) or V(B), it is helpful if the discloser identifies here the sections of the Internet-Draft or RFC that are alleged to be so covered:
