Differential fault attacks against AES tampering with the instruction flow

摘要: Most of the attacks against Advanced Encryption Standard based on faults mainly aim at either altering temporary value message or key during computation. Few other tamper instruction flow in order to reduce number round iterations one two. In this work, we extend idea and present fault AES algorithm that exploit misbehavior last round. particular, consider cause skip, repeat corrupt four functions. principle, these are applicable both software hardware implementations, by targeting execution instructions control logic. As conclusion countermeasures must also cover not only processed data.
