ADLINK cPCI-3510 Series - Manual (Page 41)

Functional Description 27
cPCI-3510
The key features Trusted Platform Module (TPM) offers are:
X Fully compliant to the Trusted Computing Group (TCG)
Trusted Platform Module (TPM) version 1.2 specification
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
X In addition to encryption key created by user. it also provide
some security features to protect the integrated circuit 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.
3.7 Battery
The cPCI-3510 is equipped with a 3.0V "coin cell" lithium battery
for the Real Time Clock (RTC). The battery socket is equipped on
the DB-3CFAST daughter board. The lithium battery must be
replaced with an identical battery or a battery type recommended
by the manufacturer. A Rayovac BR2032 is equipped on board by
default, and can be optionally equipped with a Gold Capacitor
(Panasonic EECS5R5H105).
