ST, Thanks for the reply and the leads. Actually the RN 2.0 spec is out and we all gave them our feedback. Most probably the 2.0 will be voted in by Oct. cheers and have a nice weekend -----Original Message----- From: Satish Thatte [mailto:satisht@microsoft.com] Sent: Saturday, September 16, 2000 5:18 PM To: 'Krishna Sankar'; Mishra, Prateek; xml-dist-app@w3.org Cc: Chippada, Radhika; 'Prasad Yendluri'; 'Vidya Narayanan (Extricity)' Subject: RE: SOAP header for authentication etc Prateek and Krishna, This is belated but perhaps still relevant. Prasad and Vidya should be able to provide authoritative information about RNIF 2.0 security features. The final version of BizTalk Framework 2.0 (due out in about a month) will have message-level security features centered on S/MIME 3 (in common with RNIF 2.0 to the best of my knowledge).

As you have mentioned, it is useful to learn from and work with existing standards, especially in case of Rosettanet. IMHO, BizTalk has a lot of synergy with RosettaNet - more synergy than commonality, which is good. 1. As you had mentioned, certificates and SSL (client+server authentication) transport gives RosettaNet wire level security. 2. And we can use the identity from the certificate for authC and authZ. 3. I am not happy with the current repudiation method, as it is the responsibility of the sender/receiver to store the messages plus some non-repudiable timestamp - which requires some good time service.(The sender/receiver also need to store the CRLs). I would rather see this happening at the infrastructure/framework level like from a BizTalk implementation (plus some third party time servers providing the non-repudiable time service) 4. Rosettanet does have digital signature for integrity which we could model after for BizTalk. They use the detached signature approach. 5. Rosettanet does not have encryption which I think it plans to rectify in ver 2.0. 6. I do not know what other security aspects are forthcoming in the RosettaNet 2.0 version. cheers -----Original Message----- From: Mishra, Prateek [mailto:pmishra@netegrity.com] Sent: Wednesday, July 05, 2000 11:25 AM To: 'Krishna Sankar'; 'xml-dist-app@w3.org' Cc: Chippada, Radhika Subject: RE: SOAP header for authentication etc Hi Krishna, You mentioned RosettaNet which is a good example of an existing B2B framework. It might be useful to analyze the existing security framework in RosettaNet in regards to security (Authentication, Authorization). My understanding is that RosettaNet primarily uses transport-level security secured by HTTPS + Client certificates for Authentication. The subject common name is used to figure out the identity of the individual or service pushing the document (transport identity). Authorization is derived from transport identity and Activity Name. Roughly speaking, this translates to: Is this identity authorized to carry out this activity? PIPs also specify Non-repudiation of receipt and Origin and Content. In RosettaNet, this simply means that the sender or receiver agree to store the receipt or original document for an agreed upon period of time in its original form. Additional security is available thru Business Data Entity Security. This basically means that individual data items can be encrypted, included in a message digest and digitally signed. Is that a complete list of security features within RosettaNet? How far do we need to go beyond this list in XML Message Exchange frameworks? - prateek mishra Netegrity, Inc.
