TrustLogic also provides a detailed, time-stamped transaction audit log, protected by a cumulative hash. TrustStream provides for fine-grained field by field encryption of different XML data elements, under different kinds of application keys. Conclusive feels this will allow business rules to drive PKI and security and speed the development of complete PKI security solutions. NIST is developing a complete suite of cryptographic standards for symmetric key encryption, hashing functions message authentication, digital signatures and key management. NIST expects to have the AES approved as a FIPS this fiscal year.
Counter mode is needed to effective allow high-speed pipelined or parallel implementations.
A workshop on the subject is planed for this August in Santa Barbara, following the Crypto 2001 Conference. Finally, NIST held a workshop in February 2000 on Key Management, and is now starting to work on a two tiered approach to key management standards. There was also some discussion about several proposals in the IETF and ISO to make use of the Internet domain name system to locate appropriate directory servers, given either civil or domain names. It's not clear what the ultimate outcome will be here, but the bridge will start out using X.500 chaining to avoid these problems for the time being. Please send comments or suggestions to Bill Burr .
