PHYSICAL SECURITY POLICY

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

are physically protected from unexpected disclosure and modification. Security module is

tamper evident, encapsulated in an opaque package. Regular visual inspection must be

conducted by user to check that HW integrity of the chip has not been damaged. Some

physical security protection mechanisms beyond the requirements for level 2 have been

implemented and are described in

“Mitigations of other attacks”.

Normal operating ranges are defined in the respective TOE datasheet [ST33TPHF2ESPI DS]

/ [ST33TPHF20SPI DS] / [ST33TPHF2EI2C DS] / [ST33TPHF20I2C DS]:



Temperature:

The normal operating temperature range of the security module is -40°C to +105°C.



Voltage:

The normal operating voltage range of the security module is 1.8V or 3.3V (±10%).



Frequency:

The internal system clock is created by an internal oscillator.

Operation outside these ranges is not guaranteed, but physical security mechanisms are

implemented to assure that CSPs remain protected from unauthorized disclosure, usage,

modification or deletion.
