Description

technical field [0001] The present application relates to the technical field of security attack evaluation, in particular to a fault injection attack method, device, electronic equipment and storage medium. Background technique [0002] Fault injection attack is an important method to verify the reliability of encryption chips. This method mainly uses power manipulation, electromagnetic manipulation or laser injection to affect the normal encryption operations of encryption chips, causing encryption errors to occur. The error data analyzes the encryption key to verify whether the function of the encryption chip is safe. The above attack method can be abstracted as injecting a fault signal of a certain strength into the encryption chip that is performing encryption operations at a specific physical location and at a specific moment, thereby generating encrypted error data. It can be seen that the factors that generate encrypted error data include Parameters such as attack p...
