It implements version 1.2 of the Trusted Computing Group (TCG) specification for Trusted Platform Modules (TPM). The TPM includes a cryptographic accelerator capable of computing a 2048-bit RSA signature in 500 ms and a 1024-bit RSA signature in 100 ms. Performance of the SHA-1 accelerator is 50 µs per 64-byte block. In most cases, TCG key generation operations will be completed using a proprietary mechanism in less than 1 msec. Table 1.
