Method cryptographic revocation was using a smart card

This invention relates to a cryptographic method and a chip card for carrying out the method. The cryptographic method includes: - before any calculation by calculation means of the smart card, to read (2) by the smart card into a storage means of a second entity a first list of identifiers of the entities a smart card, said list being associated with each state assigned to each of the first entity by the second entity, - comparing (3), the smart card, the identifier stored in the map storing means chip and the contents of the list to allow (5) or prohibit (4) while calculating means for calculating based on the result of the comparison.
