DEVICE CONTROLLER AND METHOD OF ENFORCING TIME-BASED SECTOR LEVEL SECURITY

摘要

A device controller interfaced between an electronic processing device and a sector-based data storage device, includes a processor connected to a clock, and a computer memory having a control list stored therein. A control list including a security feature entry including a target sector range, time data associated with the target sector range, and at least one security response associated with the target sector range. The processor determines, based at least in part on interrogation of the control list and a clock time, the time data of the entry conflicts with the clock time, and executes the at least one security response. Time data can represent an expiration date or a time window, with a conflict arising if the clock time is beyond the expiration date or within the time window, respectively.

1. A device controller interfaced between an electronic processing device and a sector-based data storage device, said controller comprising:
at least one processor communicatively connected to a clock and at least one computer memory having stored therein a control list including at least one security feature entry respectively including a target sector range, time data associated with the target sector range, and at least one security response associated with the target sector range; wherein for a particular one of the at least one security feature entry, said at least one processor determines based, at least in part, on interrogation of the control list and a clock time generated by the clock, the time data of the particular entry conflicts with the clock time, and executes the at least one security response of the particular entry.
