RAM Laboratories has developed a coprocessor-based security system called the Trusted Platform Security Manager (TPSM). The TPSM includes a coprocessor that resides within the host via the PCI or PCI/X slot and provides services to support security agents that run on the host. These agents directly monitor the protected assets on the host and request support from services running within the TPSM coprocessor. The services provided by the TPSM coprocessor include pseudo-random number generation, storage of protective assets, encryption, hash services, and monitoring / support / repair of the security agents. The solution is out-of-band to an attacker who does not have physical access to the machine, an ideal solution when the host platform is connected to a larger network. Additionally, the TPSM card has a capability to trigger notifications of tamper in cases where it is fielded on unattended platforms.
