Re: Trusted timestamping
+ Fearghas McKay fm-li...@st-kilda.org: http://www.itconsult.co.uk/stamper.htm Has been around since ~1995 and just works whenever I have used it, albeit some time ago. It publishes time stamp info on Usenet, comp.security.pgp.announce which shows the last activity was in 2002... http://groups.google.com/group/comp.security.pgp.announce/browse_thread/thread/d25667d87c1740f6# Which seems to support your viewpoint. As explained at http://www.itconsult.co.uk/stamper/stampnew.htm they moved to alt.security.pgp in 2002. But ... the latest timestamp summary I can see there is from May 2009, so I guess the point stands, unless it's just google groups that won't cooperate. (Hmmm, my news server doesn't even carry alt.security.gpg, so I can't check further. Not a good sign.) - Harald - The Cryptography Mailing List Unsubscribe by sending unsubscribe cryptography to majord...@metzdowd.com

Re: Kaminsky finds DNS exploit
+ John Kemp [EMAIL PROTECTED]: It does seem he would like an air of some mystery to exist though until he makes his presentation about the issue at Defcon - did he, himself, discover something new? We'll just have to wait, unless we go play with the BIND code ourselves. Unless he is merely blowing smoke, it would seem that he discovered some little twist that makes the known vulnerability much more easily exploitable than previously assumed. That would explain his statement: the patch fixes a well known vulnerability, and as a side effect stops the more serious attack, in effect making it hard to tell what is involved in that attack from reading the patch. - Harald - The Cryptography Mailing List Unsubscribe by sending unsubscribe cryptography to [EMAIL PROTECTED]
Find me a hash
Susan Landau has an article in the upcoming March issue of Notices of the AMS: Find me a hash. There is a short preview of the article here: http://www.eurekalert.org/pub_releases/2006-02/ams-dsa020106.php it even includes a non-public (whatever that means) link to the paper itself: http://www.ams.org/staff/jackson/fea-landau.pdf Readers of the cryptography list may not learn anything new from it, but it seems like a nice summary of the present state of affairs. The article opens by calling hash function the duct tape of cryptography, and ends with these words: What is the theory of hash functions? It is not often that mathematicians are asked to develop a theory for duct tape, but there is a clear and present need to do so now for cryptographic hash functions. - Harald - The Cryptography Mailing List Unsubscribe by sending unsubscribe cryptography to [EMAIL PROTECTED]
