发明名称 DATA PROCESSING METHOD AND DEVICE
摘要 The method involves verifying a criterion indicating normal progress of the method and effectuating processing during negative verification. The processing step is separated from the verification step by an intermediate step of non-null duration. The criterion is negative if an erroneous signature is provided, an anomaly is detected, an attack is detected, or a functional error is detected. An independent claim is also included for a data processing device.
