Security features
Designed to meet the physical security requirements
of FIPS140 and Common Criteria certifications
Fine-line, top-level metal pattern detects intrusion of
the chip鈥檚 cryptographic boundary
Additional on-chip sensors detect out-of-range
environmental conditions that generate a tamper
response
The equipment enclosure can be monitored by
tamper response inputs for added protection
Fast write SRAM technology causes rapid
鈥渮eroization鈥?of secure information as a tamper
response
Eavesdropping on the external memory bus
prevented by single or triple -DES encryption of the
programs
Internal chip clock isolated from external system
clock by phase-locked loop
Asynchronous internal ring oscillator provides clock
for arithmetic operations
Resources inside cryptographic boundary include:
鈭?/div>
Modulo Arithmetic Accelerator (MAA) for up to
4096-bit (e.g., PKI)
鈭?/div>
DES and 112-bit key triple -DES engines
available for secret key cryptography
鈭?/div>
Random number generator
鈭?/div>
Memory Management Unit and 1kB cache
鈭?/div>
Firmware bootstrap loader resides in a 16kB
factory-programmed ROM
8051 compatible with expanded addressing
Linear address space directly accesses up to 8MB
of external memory
Dedicated memory and parallel I/O bus saves port
pins
Four 8-bit ports, one 6-bit port
