Does ACP support secure link-local multicast? The issue here is that GRASP has no choice but to use multicast for discovery or flood messages, and such messages are intrinsically insecure. So this isn't really an open issue for the protocol, but it is a question for the ACP designers. Can they provide an ACP virtual interface that supports secure LL multicast? For the GRASP draft, this should probably be changed from being an open issue into a specific paragraph in the Security Considerations.

The us= e case was that an autonomic agent on a physical device may well control ot= her devices which are possibly non-autonomic. This transaction would not be= inside the ACP (because the other device is non autonomic). So an ASA can = have ACP based interactions, and non-ACP based interactions.=20 I think there are different aspects to what you're saying:=20 - GRASP should ONLY run in the ACP. (I think this is what you mean, really,= and I think we agree on that) - But GRASP can negotiate ANYTHING. In fact, one negotiation objective coul= d be the IP address of the peer node in the data plane. Why not? So the negotiation itself is in the ACP, the data exchanged may refer to so= mething outside the ACP, and now *IF* you were to do a connection to that a= ddress, you wouldn't be protected by the ACP any more.=20 But that's ok (in my opinion), as long as the context is explicit. I.e. the= ASA *knows* it's dealing with something outside the ACP. I had proposed a = long time ago a "context", which could then point to the data plane (or oth= er virtual contexts).=20 Michael > -----Original Message----- > From: Anima [mailto:anima-bounces@ietf.org] On Behalf Of Brian E > Carpenter > Sent: 04 February 2016 01:49 > To: Anima WG > Subject: [Anima] GRASP Issue 42: ACP bypass? >=20 > o 42.

The use case was that an autonomic agent on a physical device may well control other devices which are possibly non-autonomic. This transaction would not be inside the ACP (because the other device is non autonomic).

In fact, one negotiation objective could be the IP address of the peer node in the data plane. Why not? The IP address, or FQDN if you prefer. Certainly possible. > So the negotiation itself is in the ACP, the data exchanged may refer to something outside the ACP, and now *IF* you were to do a connection to that address, you wouldn't be protected by the ACP any more. > > But that's ok (in my opinion), as long as the context is explicit. I.e. the ASA *knows* it's dealing with something outside the ACP. I had proposed a long time ago a "context", which could then point to the data plane (or other virtual contexts). Right. What I think would be dangerous is for GRASP discovery to return an address which is not secured, i.e. is not an ACP or TLS-wrappable address. That would allow an ASA to slide gently from secure to insecure without knowing about it. So I think this can be resolved by some text in the Security Considerations.

A future consideration is to allow multiple objectives in rapid mode for greater efficiency. My suggestion: leave this for the future, because it would cause considerable complexity for ASA designers (multiple independent negotiation threads triggered by a single message).

This draft is a work item of the Autonomic Networking Integrated Model and Approach of the IETF. Title : A Generic Autonomic Signaling Protocol (GRASP) Authors : Carsten Bormann Brian Carpenter Bing Liu Filename : draft-ietf-anima-grasp-03.txt Pages : 57 Date : 2016-02-23 Abstract: This document establishes requirements for a signaling protocol that enables autonomic devices and autonomic service agents to dynamically discover peers, to synchronize state with them, and to negotiate parameter settings mutually with them. The document then defines a general protocol for discovery, synchronization and negotiation, while the technical objectives for specific scenarios are to be described in separate documents. An Appendix briefly discusses existing protocols with comparable features.

Also clarified narrative explanation of discovery relaying. Protocol change: Split Request message into two (Request Negotiation and Request Synchronization) and updated other message names for clarity. Protocol change: Dropped unused Device ID option. Further clarified text on transport layer usage. New text about multicast insecurity in Security Considerations. Various other clarifications and editorial fixes, including moving some material to Appendix. And here are the remaining open issues: o 7. Cross-check against other ANIMA WG documents for consistency and gaps. o 43. Rapid mode synchronization and negotiation is currently limited to a single objective for simplicity of design and implementation. A future consideration is to allow multiple objectives in rapid mode for greater efficiency. o 48. Should the Appendix "Capability Analysis of Current Protocols" be deleted before RFC publication? I will post an updated version of the Python prototype later today.

This message announces a new limited release of the code, updated for draft-ietf-anima-grasp-03. The code is marked as copyrighted, but anybody is welcome to try it. Pleas read the "health warning" at the beginning of the source file. Updated documentation and several Python files can be found at https://www.cs.auckland.ac.nz/~brian/graspy/ PLEASE read graspy.pdf first.
