Re: Network Layer Encryption History and Prior Art

The research and development of "Network Security" started in the
late 70's at BBN with the development of the "IPLI". Classified
research and development continued in this area on the Blacker
(Unisys) and Caneware (Motorola) programs in the early 80's. The NSA
sponsored Secure Data Network System (SDNS) project brought together
a variety of vendors that created the early SP3, KMP and MSP
specifications. SP3 provided network layer security services that
included a tunneling mode. SP3 is very similar to the IPsec working
group ESP specification. The Key Management Protocol (KMP) is
similar to the ISAKMP specification in concept, but used ASN.1 for
specifying the protocol formats. Much of the SDNS work was openly
published starting in about 1988. The Motorola Network Encryption
System (NES) is an SDNS device and was designed in the mid to late
80's.
Paul, thanks for the history lesson!!
John (Gilmore), is this what you were looking for in terms of real Prior
Art to take to Rick Adams, so he'll drop the patent claims? The SP3
specifications should hopefully be detailed enough to satisfy a Patent
Attorney as being Real Prior Art in the Patent Context. The only
question is whether or not there's enough there to take out all of the
claims in UUNET's patent (or at least enough so that IPSEC won't be have
to worry about infringing the UUNET patent.)
