Abstract
Systems, apparatus, methods, and techniques for functional safe execution of encryption operations are provided. A fault tolerant counter and a complementary pair of encryption flows are provided. The fault tolerant counter may be based on a gray code counter and a hamming distance checker. The complementary pair of encryption flows have different implementations. The output from the complementary pair of encryption flows can be compared, and where different, errors generated.
