Functional Description 19cPCI-69303.6 TPMThe cPCI-6930 is equipped with the Infineon SLB 9635 TT 1.2Trusted Platform Module (TPM), a security controller with crypto-graphic functionality that provides users a secure environment ine-commerce transactions and Internet communications. The keyfeatures provided by the TPM are:X Hardware hash accelerator for SHA-1 algorithmX Advanced Crypto Engine (ACE) for asymmetric key operations(up to 2048-bit key length) to make hardware protection.X Tick counter to extend the time required to decipher the keyX Over/Under-voltage detection to monitor the system stabil-ity. If the voltage fluctuates dramatically, this function canblock 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 setby tick counter is receivedX Memory encryption to protect memoryX Physical shield in the IC to protect the die from intruding orhacking by matching the data transferred on the 2 layermetal shield on the IC. If the data is not matched, the ICmay be blocked.3.7 BatteryThe cPCI-6930 is provided with a 3.0V “coin cell” lithium batteryfor the Real Time Clock (RTC). The lithium battery must bereplaced with an identical battery or a battery type recommendedby the manufacturer.
