I have not finished my own investigation, and so have not answered you. I forwarded the note (for informative purposes) to the IAB and IESG as well. I have sent messages to a number of individuals who have been leaders in the IPSEC working group, only two of which work at Cisco, asking them A process complaint with regard to IPSEC has been sent to me. Do you see any reason for a process complaint in the working group? I have gotten back about 84K of mail discussing the history of the group from various folks' perspectives. I have also been reviewing the archived minutes. There are some issues with your complaint. To name one, you state that in October 1994, SKIP was the only solution on the table. The minutes show that in March 1994, Phil Karn was presenting Photuris to the working group, and the recollection of those polled is that there was code being published by Phil, Hugo, and someone else. They may not have had an internet draft, but they most certainly had proposals. So it is not clear that all aspects of your complaint bear scrutiny. As to the lateness of ISAKMP/Oakley, all concerned tell me that it is in actuality little more than Photuris written up by someone other than Bill Simpson, who has since relinquished his imagined rights to Photuris. As to whether SKIP meets the working groups objectives, all concerned tell me that as early as 1992 there was a consensus regarding the class of solution the working group would publish. This is apparently recorded on slides that Paul has not published as minutes, but is remembered by all the folks I have polled. The consensus was around a solution of the general character of Photuris or ISAKMP - Diffy-Hellman with attribute negotiation. All concerned also tell me that SKIP is appropriate for a certain class of network and a certain class of security problem, and would be interesting therefore as an elective protocol. They tell me that negotiations with the SKIP camp have not broken down over whether SKIP would be published at all, but over whether SKIP would be mandatory to implement. They tell me that the working group at this point has no consensus as to which solution to deploy; one portion is very interested in SKIP, one is very interested in a Diffy-Hellman algorithm with attribute negotiation, and one is deeply confused and simply wants a standard chosen. The Area Director tells me that, consistent with IETF history, the only solution he can require implementation of is a solution which is general enough for the internet. It is his considered opinion (and that of the security directorate), stated last night, that ISAKMP/Oakley is a more general solution than SKIP, and is better suited to the general requirements of the internet. As to your specific concerns about Ran, neither the IESG nor IAB has ruled specifically on his actions or comments. It is my personal belief, based on conversations with him, that he is not biased against Sun or against you; however, he honestly does not believe that SKIP meets the requirements that the working group laid out in 1992. He has - and others have - technical concerns, which are not hidden. In such a case, it is the responsibility of a working group chair to either require that the objections be met or find another solution. You may have valid concerns with the way he has done so (I am not going to make a judgement call on that at this point), but I have to say that he has acted in a manner consistent with that guideline. As to the potential conflict of interest inherent in Ran working for an employer who is working on security issues, please observe that this is common in the IETF. John Moy, the author and designer of OSPF, chaired that working group. Proteon, his employer, deployed the first implementation. I have chaired several working groups, and my employer has deployed products containing those protocols. In fact, it is unusual for someone to be interested in leading a working group whose employer is not working on a solution to that problem. If there is a conflict of interest in Ran working for Cisco, it is a commonly shared problem. =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= I don't suffer from insanity. I enjoy every minute of it.
