NON-PROPRIETARY DOCUMENT

MITIGATIONS OF OTHER ATTACKS

The security module meets Physical Security protection requirements for FIPS level 2.

7.1

Internal Tamper Detection

The security module contains an active metal shield that covers the internal TPM circuitry and

memory components. Cutting, removing or modifying the shield layer will cause the TPM to

Reset and enter a SHUTDOWN mode.

7.2

Environmental protection

The security module contains circuitry which will detect environmental conditions outside the

range described in the product datasheet. Power supply voltage is continuously monitored. If

conditions exist outside the range determined by the TPM tamper detection circuitry, the chip

will reset and will enter a FAILURE mode. The chip will remain Reset and in FAIL mode as

long as the environmental condition causing the tamper event persists.
