Abstract:
A system and method of securing data stored in a memory are disclosed. The method comprises storing a payload data in a memory in one of first and second states related by a transform, reading the payload data from the memory, attempting to use the payload data for an application, verifying the payload data as being in the first state, transforming the payload data as a function of the transform in response to verifying that the payload data is in the second state, and repeating performing the verifying and transforming steps until the payload data is verified as being in the first state.
