摘要
A method for monitoring the execution of a sequence of instruction codes in an integrated circuit comprising a central processing unit provided for executing such instruction codes. Current cumulative signatures are produced using deterministic address, control or data logic signals involved in the execution of the sequence and taken off at various points of the integrated circuit. A final cumulative signature is compared with an expected signature and an error signal is produced if the two signatures are not identical. Particularly useful to secure integrated circuits for smart cards.
