| I'm about to implement an OTPasswd (mostly like s/key) scheme to my | www browsers/clients/proxy, but I was wondering is the mere principle | of storing H^n(S) and requesting H^(n-1) from peer (H beeing your | favorite one way strong hash function (MD5), and S your seed+secret | passwd) could possibly be patented somehow and thus preventing using a | similar scheme without getting a license (from | bellcore?),.... if there are any usage conditions/restrictions?,... There is an IETF working group standardizing OTPassword technology. not sure how active it still is. ietf-otp-request@@bellcore.com Adam -- "It is seldom that liberty of any kind is lost all at once." -Hume
