PROVISIONING OF SECURE STORAGE FOR BOTH STATIC AND DYNAMIC RULES FOR CRYPTOGRAPHIC KEY INFORMATION

摘要

A media processing device includes a one time programmable (OTP) memory to store a first set of cryptographic keys and rule set for the first set of cryptographic keys, a key store memory, and a rule set memory. The media processing device further includes an arbitration module to provision: a first segment of the key store memory to store cryptographic keys from the one-time programmable (OTP) memory; a first segment of the rule set memory to statically store rules for the cryptographic keys stored in the first segment of the key store memory; a second segment of the key store memory to store cryptographic keys; and a second segment of the rule set memory to store rules dynamically generated during operation of the media processing device for cryptographic keys stored in the second segment of the key store memory.
