  • Patent number: 7139911
    Abstract: A method of certifying a host-identification mapping extension included in a digital certificate, the digital certificate issued and signed by a specific certification authority. In an exemplary embodiment of the invention, the method includes assigning a trust value for each certification authority included in a set of certification authorities. A digital certificate containing the host-identification mapping extension therein is received, with the host-identification mapping extension further containing a plurality of identification attributes therein. The plurality of identification attributes are evaluated, along with the trust value assigned to the specific certification authority issuing the digital certificate. A determination is then made, based upon the plurality of identification attributes and the trust value, as to whether the host-mapping extension is to be certified.

  • Patent number: 7062655
    Abstract: An exemplary embodiment of the invention relates to a method, system, and storage medium for determining trivial keyboard sequences of proposed passwords. The system comprises a user system with associated keyboard input device; a server in communication with the user system via a communications link; a data storage device coupled to the server, the data storage device housing a database including a keyboard profile for specifying a physical layout of character and function keys on the computer keyboard input device; a master password database including a user account associated with the user system; and a password verification mechanism executable by the server. Upon execution, the password verification tool performs an algorithm on the proposed password and determines triviality according to criteria specified in the algorithm.
