Patent Number Title Of Patent Date Issued
8132006 Cryptographic authentication and/or establishment of shared cryptographic keys, including, but n March 6, 2012
A server (120) uses a password (.pi.) to construct a multiplicative group (Z.sub.N*) with a (hidden) smooth order subgroup (<x'>), where the group order (P.sub..pi.) depends on the password. The client (110) uses its knowledge of the password to generate a root extraction problem
7831998 Changing states of communication links in computer networks in an authenticated manner November 9, 2010
A protocol for closing all active communication links between one device (110.1) and one or more other devices in a group provides that the first device sets up the group by generating an input to a predefined function (e.g. one-way function) according to some random distribution, comput
7814320 Cryptographic authentication, and/or establishment of shared cryptographic keys, using a signing October 12, 2010
Using a password (.pi.), a client (C) computes part (H.sub.1(<C,.pi..sub.C>) of the password verification information of a server (S), and together they use this information to authenticate each other and establish a cryptographic key (K'), possibly using a method resilient to
