Patent abstract
Methods and devices that may be utilized in systems to dynamically update a security version parameter used to encrypt secure data are provided. The version may be maintained in persistent storage located on a device implementing the encryption, such as a system on a chip (SOC). The persistent storage does not require battery backing and, thus, the cost and complexity associated with conventional systems utilizing battery backed storage may be reduced.
