Encryption module with physical security or protection

摘要

This invention concerns an encryption module having a cryptographic adapter configured for connection to a host system bus to manage host computer access via a secure access policy implemented in firmware on the adapter. The invention in particular concerns the physical security measures applied to such a module to maintain its operational integrity. To do this the adapter is encased in a sealed cover which is designed with thermal characteristics so that a steady state temperature is achieved during use that is safe for continuous operation. The module further comprises tamper detection devices including a software configurable tamper detection component to induce a tamper response upon removal of adapter from the host system bus.
