ABSTRACT:
An online trusted platform module (TPM) in communication with a security module that can be located elsewhere in the network in a server machine. In an embodiment, the online TPM is connected directly to a network interface card (NIC) that is also resident at the client. This allows the online TPM to communicate directly to the network, and therefore to the security module (without having to deal with the TCP/IP stack at the client machine in some circumstances, e.g., the boot process). In an embodiment, the communications channel between the online TPM and the security module is implemented using the transport layer security (TLS) protocol. A secure boot process is performed in advance of security processing. Typical security processing includes receipt, by the online TPM, of one or more commands from an application. The online TPM then proxies out the commands to the security module. After the security module has completed its processing of the commands, results of the processing and any related status information is returned to the online TPM.
