From: Robert Hettinga Subject: DCSB: Pat Cain; Trustable Internet Time and Digital Commerce Date: Tuesday, November 16, 1999 5:14 PM The Digital Commerce Society of Boston Presents Pat Cain, GTE Internetworking Does anybody know what time it is? (And can prove it?) Tuesday, December 7th, 1999 12 - 2 PM The Downtown Harvard Club of Boston One Federal Street, Boston, MA As more and more things become internet-enhanced, the ability to note when a certain event happened is based upon the timestamp generated from a computer. In most cases the computer's concept of time was retrieved from a trusted server using the internet Network Time Protocol (NTP). This talk will show some examples where trustable time is beneficial and problematic, followed by a quick overview of the NTP protocol and the assurance enhancements proposed as part of the IETF Secure Time WG. The talk will conclude with an unsolved problems discussion. Pat Cain is a principal member of the technical staff, and security advocate, at GTE Internetworking. Mr. Cain provides consulting and guidance to both internal and external clients on the realistic use of security technologies. In Mr. Cain's 18 years at GTE/BBN, he was the lead engineer of the MISSI CAW (a medium-assurance X.509 CA), was the hardware architect of the BBN SafeKeyper, and did numerous cryptographic and network security projects. He currently represents GTEI in ANSI X9F, is a member of the ABA Information Security Committee, and is the co-chair of the IETF's Secure Time working group. This meeting of the Digital Commerce Society of Boston will be held on Tuesday, December 7th, 1999, from 12pm - 2pm at the Downtown Branch of the Harvard Club of Boston, on One Federal Street. The price for lunch is $35.00. This price includes lunch, room rental, A/V hardware if necessary, and the speakers' lunch. The Harvard Club *does* have dress code: jackets and ties for men (and no sneakers or jeans), and "appropriate business attire" (whatever that means), for women. Fair warning: since we purchase these luncheons in advance, we will be unable to refund the price of your lunch if the Club finds you in violation of the dress code. We need to receive a company check, or money order, (or, if we *really* know you, a personal check) payable to "The Harvard Club of Boston", by Saturday, December 4th, or you won't be on the list for lunch. Checks payable to anyone else but The Harvard Club of Boston will have to be sent back. Checks should be sent to Robert Hettinga, 44 Farquhar Street, Boston, Massachusetts, 02131. Again, they *must* be made payable to "The Harvard Club of Boston", in the amount of $35.00.
