Functional Description 21
cPCI-6210
3.6 Trusted Platform Module
Upon request, the cPCI-6210 supports the Infineon SLB 9635 TT
1.2 Trusted Platform Module (TPM), a security controller with cryp-
tographic functionality that provides users a secure environment in
e-commerce transactions and Internet communications.
The key features the TPM provides are:
X Hardware hash accelerator for SHA-1 algorithm.
X Advanced Crypto Engine (ACE) for asymmetric key opera-
tions (up to 2048-bit key length) to make hardware protec-
tion.
X Tick counter to extend the time required to decipher the key.
In addition to an encryption key created by the user, the TPM also
provides security features to protect the TPM itself:
X Over/Under-voltage detection to monitor the system stabil-
ity. If the voltage fluctuates dramatically, this function can
block the data transfer and lock the chip.
X Low/High frequency sensor to detect the IC clock fre-
quency. If the frequency fluctuates dramatically, this func-
tion can block the data transfer and lock the chip.
X Reset filter to filter reset signal in order to break the time set
by tick counter is received.
X Memory encryption to protect memory.
X Physical shield in the IC to protect the die from intruding or
hacking by matching the data transferred on the 2 layer
metal shield on the IC. If the data is not matched, the IC
may be blocked.
NOTE: NOTE:
The TPM does not support operation below 0ºC. Below this
temperature, the system may not boot. As a result, the
Extended Temperature versions of the cPCI-6210 are not avail-
able with TPM.
