Abstract
A method of verifying the integrity of code in a programmable memory, the method including: receiving the code from an insecure memory; generating error detection bits for the code as it is received from the insecure memory; storing the code and the error detection bits in the programmable memory; and verifying the integrity of the code stored in the programmable memory by performing an authentication check on the code and the error detection bits stored in the programmable memory.
