摘要： A device includes a key store memory, a rule set memory, a plurality of cryptographic clients, and a key store arbitration module. The key store memory stores a plurality of cryptographic keys and the rule set memory stores a set of rules for accessing the cryptographic keys. A cryptographic client is operable to issue a request to access a cryptographic key(s) and, when access to the cryptographic key is granted, execute a cryptographic function regarding at least a portion of the cryptographic key to produce a cryptographic result. The key store arbitration module is operable to determine whether the request to access the cryptographic key is valid; when the request is valid, interpret the request to produce an interpreted request; access the rule set memory based on the interpreted request to retrieve a rule of the set of rules; and grant access to the cryptographic key in accordance with the rule.

摘要： A device includes a key store memory that stores one or more cryptographic keys. A rule set memory stores a set of rules for accessing the cryptographic keys. A key store arbitration module grants access to the cryptographic keys in accordance with the set of rules. The device can be used in conjunction with a key ladder. The device can include a one-time programmable memory and a load module that transfers the cryptographic keys from the one one-time programmable memory to the key store memory and the set of rules to the rule set memory. A validation module can validate the cryptographic keys and the set of rules stored in the key store and rule set memories, based on a signature defined by a signature rule.
