In your previous mail you wrote: we felt that cga compatibility was more important than supporting equal iids in the HBAs of a given set (note that we do see some value in having equal iids, for instance for simplified management, but this cannot be provided in the CGA format) => I agree. In fact, to get the same IID for all prefixes is not a good property IMHO. > What do you mean by reliability here ? fault tolerance i.e. the fault tolerance and other features provided by the multi6 protocol based on the usage of HBAs i will try to reword this in the draft => you should because HBAs are compatible with CGAs... > 4)When the multi6 state is setup, i assume that the CGA parameter is > exchanged between the > communicating parties. if you mean the CGA parameter data structure including the multiprefix extension, then yes (BTW i need to state this explicitly in the draft) => the CGA draft is pretty clear about this. > One of the inferences from the security consideration section is > that the attacker cannot create an HBA > set given a set of victim's addresses. It was not very obvious by > reading the security consideration section. agree, i will include an example of usage and possible attempts of attacks, and see if this improves this point => in fact this is clearer in the CGA document: this problem is to the good parameters which will hash to the given 59+16*sec bits (note the number of prefixes don't really matter, i.e., it doesn't add or remove bits to the problem to solve for attackers). Thanks [email protected] PS: BTW CGA IPR holders provide royalty-free licenses only for SEND, can they update their IPR texts on the IETF web for HBAs too?
