DYNAMIC KEY AND RULE STORAGE PROTECTION

A media processing device includes a key store memory to store a plurality of cryptographic keys and a rule set memory to store a plurality of rules for the plurality of cryptographic keys. The media processing device further includes an integrity module to determine a first cyclical redundancy check (CRC) value from the plurality of rules stored in the rule set memory and compare the first CRC with a second CRC value associated with the plurality of rules. The media processing device further includes an arbitration module to prevent further access to the plurality of rules in the rule set memory responsive to the integrity verification module signaling a mismatch between the first CRC and the second CRC.
