Abstract
A system and method of verifying a content of a non-volatile reprogrammable memory communicatively coupled to a microprocessor is disclosed. The method comprises the steps of reading at least a portion of the data stored in the non-volatile reprogrammable memory via a second communication path secured by encryption, generating a computed integrity value according to at least a portion of the contents of the non-volatile reprogrammable memory, and reading an integrity value, and comparing the computed integrity value with the read integrity value.
