Abstract:
The invention describes a method for hardening a security mechanism against physical intrusion and substitution attacks. A user establishes a connection between a network peripheral device and a network via a security mechanism. The security mechanism includes read only memory (ROM) that contains code that initiates operation of the mechanism and performs authentication functions. A persistent memory contains configuration information. A volatile memory stores user and device identification information that remains valid only for a given session and is erased thereafter to prevent a future security breach. A tamper-evident enclosure surrounds the memory elements, which if breached, becomes readily apparent to the user.
