A. For granted patents or published pending patent applications, please provide the following information:
|Patent, Serial, Publication, Registration, or Application/File number(s)||
U.S. Patent 5,511,122
Notes: To: firstname.lastname@example.org
To: Jeff Schiller, Security Area Director, IETF, <email@example.com>
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B. Does this disclosure relate to an unpublished pending patent application?:
|Has patent pending||No|
