EN Concurrent Error Detection (CED) techniques based on hardware or time redundancy are widely used to enhance system dependability and to detect fault injection attacks. In this paper, we present two approaches to countermeasure against fault injections into a symmetric block cipher PP-2. We proposed the hardware redundancy CED technique based on parity checks and time redundancy technique based on an inverse relationship between encryption and decryption at the round level of PP-2. Simulation results for single and multiple as well as transient and permanent faults are presented.
