Abstract
A method of securely operating a computerized system includes forming a connection to a user-removable physical security device (PSD) which is uniquely paired with the computerized system and which stories cryptographically secured data required for performing a protected function on the computerized system. The PSD may be realized as a USB or similar peripheral device containing security-related data and potentially security processing capability as well. The protected function could be decrypting of encrypted data encryption keys used to encrypt/decrypt user data for example. A user who has an established association with the PSD (e.g. by some preceding registration process) is authenticated, resulting in activation of the PSD on the computerized system. Upon such activation of the PSD, the computerized system engages in a security operation using the cryptographically secured data from the PSD to enable the protected function to be performed under control of the user on the computerized system.
