Shheeesh. I wasnt even implying the article was bad. To the contrary it was one of the best mainstream articles I have ever seen on the subject. That is why I posted the note to the list. I thought some list members could find the explanations useful. The refinement I was refering to was the authors implied acceptance of Micali's "fair crypto system" as a "solution". I could be wrong, and Im sure I will be corrected if i am, but my feelings were that this system still depended on the trustworthiness of the branches to which the "pieces" of your key would be distributed. If these were all TLAs, we still have a Denning problem, no? I thought I made it clear in the last post that i thought that the article was very good. If not I am sorry. And if your listening Peter, Great Article! --------------------------------------- Matt (Respectfully Questioning in part) mjmiski@macc.wisc.edu
