摘要

The method involves checking a set of tags during execution of a program. The set of tags is transmitted to an input of a monitoring unit during execution of identification data associated with the set of tags. The monitoring unit is arranged with a register and a processing unit for reading data stored in the register. Identification data is received in the input of the monitoring unit. A set of operations is performed to control the identification data. The processing unit is arranged to generate an interruption of execution of the program (1200) according to result of the set of operations. Independent claims are also included for the following: (1) a monitoring unit (2) a smart card.
