the Rule Array
Element
Number
Name Description
5 Low Voltage
Detected
A numeric character string containing a value to
indicate whether a power supply voltage was
below the minimum acceptable level. This may
indicate an attempt to attack the security
module:
One means only acceptable voltages have
been detected
Two means a voltage has been detected
below the low-voltage tamper threshold.
6 High Voltage
Detected
A numeric character string containing a value to
indicate whether a power supply voltage was
above the maximum acceptable level. This
may indicate an attempt to attack the security
module:
One means only acceptable voltages have
been detected
Two means a voltage has been detected
above the high-voltage tamper threshold.
7 Temperature
Range Exceeded
A numeric character string containing a value to
indicate whether the temperature in the secure
module was outside of the acceptable limits.
This may indicate an attempt to obtain
information from the module:
One means the temperature is acceptable
Two means the temperature has been
detected outside of an acceptable limit.
8 Radiation Detected A numeric character string containing a value to
indicate whether radiation was detected inside
the secure module. This may indicate an
attempt to obtain information from the module:
One means no radiation has been detected
Two means radiation has been detected.

Last Five
Commands Run
These five rule-array elements contain the last
five commands that were executed by the
Coprocessor CCA application. They are in
chronological order, with the most recent
command in element 9. Each element contains
the security API command code in the first four
characters, and the subcommand code in the
last four characters.

Last Five Return
Codes
These five rule-array elements contain the
SAPI return codes and reason codes
corresponding to the five commands in
rule-array elements 9, 11, 13, 15, and 17.
Each element contains the return code in the
first four characters, and the reason code in the
last four characters.
