M模式的基于持久性故障的碰撞攻击

he CCM operating mode can ensure the confidentiality of the data and ensure the integrity of the data.In this paper, the PFCA attack is applied to the CCM operating mode. Based on the persistence of zero faults injected in the Te box used in OpenSSL encryption, and the collision chain is constructed by constructing the input data and observation output of CCM mode encryption.Finally, the key is successfully restored.In the simulation experiment of PC, the attacks of this paper can reach 100% of the success rate at an average time consumption of less than 1 second.The experimental results show that even with authentication block cipher working mode, the attacker can also observe collision information through the message authentication code output by the authentication module, thereby restoring the key.
