Abstract:
A method of protecting a sensitive data sequence in an integrated circuit includes generating a pseudorandom sequence according to a seed sequence; combining the sensitive data sequence with the pseudorandom sequence to generate a protected data sequence; and storing the protected data sequence and the seed sequence. The sensitive data sequence is inaccessible from outside of the integrated circuit.
