Appl. No.:

10/764966

Inventors:

Michael F. Angelo - Houston TX, US
Larry N. McMahan - Fremont CA, US
Richard D. Powers - Highland Village TX, US

Assignee:

Hewlett-Packard Development Company, L.P. - Houston TX

International Classification:

H04L 9/00

US Classification:

380259

Abstract:

A method and apparatus for initializing multiple security modules are provided. The method may comprise the acts of determining if the security module is a controlling security module or a subordinate security module, generating at least one key if the security module is the controlling security module, and receiving at least one key from another security module if the security module is the subordinate security module. The apparatus may comprise a detector that is adapted to determine if the security module is a controlling security module or a subordinate security module, a key generator that generates a key for the security module if the security module is the controlling security module, and a key receiver that receives a key from another security module if the security module is the subordinate security module.

US Classification:

711164

Abstract:

The disclosed embodiments relate to a security module and a method of operating a security module. The method may comprise the acts of detecting a second security module, determining whether a key associated with the second security module is available to the first security module, and obtaining the key associated with the second security module if the key associated with the second security module is not available to the first security module. The security module may comprise a detector that is adapted to detect another security module and determine whether one of a plurality of keys is associated with the other security module, and a device that obtains at least one key associated with the other security module if the one of the plurality of keys is not associated with the other security module.
