Patent ID: 7761904

Claim:
A system for conducting secure operations utilizing a removable cryptographic ignition key (CIK), said system comprising: said removable CIK containing an embedded password; a processor configured to insertably receive said removable CIK; a proximity detector configured to determine if a distance between said removable CIK and said processor is within a predetermined distance through wireless communication between said processor and said removable CIK, said wireless communication not indicative of the password, wherein said system is configured to: enable continuing secure operations subsequent to said processor receiving said removable CIK; conduct continuous secure operations while said removable CIK is within said predetermined distance of said processor; and disable continuing secure operations when a distance between said removable CIK and said processor is greater than said predetermined distance; and said system is configured to enable continuing secure operations upon said removable CIK being inserted into and subsequently removed from said processor; a manual disable portion configured to disable continuing secure operations regardless if a distance between said removable CIK and said processor is within said predetermined distance; wherein said manual disable portion disables continuing secure operations by at least one of interrupting and disrupting a signal conveyed by the wireless communication between said removable CIK and said processor for determining if a distance between said CIK and said processor has exceeded said predetermined distance.
