Hi, As a follow-up from James Kempf presentation in the Internet Area meeting in San Diego, we have created a mailing list to discuss potential future work related to CGA and SeND extensions. The main goal is to identify possible work items that the community is interested in doing some work on. You can subscribe to the list through: https://www1.ietf.org/mailman/listinfo/cga-ext I include a list of extensions that have been proposed over the last few years that could be possible candidates to work on, depending on the interest expressed. Please note that this is rough list, so maybe some of the items included may not be clearly within the scope of the work and there may be other items that i have missed. - Proxy SeND. The idea here is to define SeND and CGA extensions so that SeND can be used with Proxy ND. Reference: draft-kempf-mobopts-ringsig-ndproxy-01.txt - Define extensions to Multi-Key CGAs: The idea here is to allow the possibility of including multiple public keys in a single CGA Parameter Data Structure, so that multiple parties can claim address ownership. Reference: J. Kempf, J. Wood, Z. Ramzan, C. Gentry, "IP Address Authorization for Secure Address Proxying using Multi-key CGAs and Ring Signatures", IWSEC'06. - Perform a threat analysis of the current dependency of CGAs with SHA-1 and Update CGAs so that other hash functions can be used. (this work is already been discussed in the Int area ml, but i guess it would benefit from additional discussion in a specialized forum). Reference: draft-bagnulo-multiple-hash-cga-01.txt - Define CGA extensions to support other public key algorithms. this would be a generic extension that would allow using other public key schemes in CGAs. In particular, the extension for using Elliptic Curve encryption have been suggested. - Usage of CGAs with IPSec. The goal here would be to use the key of the CGA to create an IPSec SA. Possible IKEv2 extensions need to be defined for this. Reference: draft-laganier-ike-ipv6-cga-01.txt - CGAs and DHCP. The goal here would be to analyze possible mechanisms to allow to assign CGAs using DHCP and to produce a recommendation about how this can be done. The actual DHCP extensions are to be defined in the DHC wg. - Define CGA extensions for including Link Layer information in the CGA. Reference: draft-laganier-send-ll-hba-00.txt - Define CGA extensions to include a certified MAC address - Define CGA extensions to include symmetric keys. Reference: draft-narayanan-pba-01.txt Other items? comments on the items above?
