ASSURING INTEGRITY AND SECURE ERASURE OF CRITICAL SECURITY PARAMETERS: abstract simplified (18208585)

• This abstract for appeared for patent application number 18208585 Titled 'ASSURING INTEGRITY AND SECURE ERASURE OF CRITICAL SECURITY PARAMETERS'

Simplified Explanation

The abstract describes a processing device that manages critical security parameters (CSPs) for a memory device. It keeps track of two CSP files, one for each set of CSPs. The device sets flags to indicate whether each CSP file exists and whether it is valid. Based on the evaluation of these flags, the device selects one of the CSP files as the active one.

Original Abstract Submitted

A processing device sets a first flag that indicates whether a first critical security parameter (CSP) file exists. The first CSP file includes a first set of CSPs for a memory device. The processing device sets a second flag that indicates whether the first CSP file is valid. The processing device sets a third flag that indicates whether a second CSP file exists. The second CSP file includes a second set of CSPs for the memory device. The processing device sets a fourth flag that indicates whether the second critical security parameter file is valid. The processing device selects one of the first or second CSP file as an active CSP file based on an evaluation of the first, second, third, and fourth flags.
