DYNAMIC DATA INTERPRETATION METHOD FOR A CHIP CARD

摘要

In order to reduce the duration for establishing verification protocols during the connection of a chip card to a reader, to reduce the risks of corruption during this operation and to limit memory occupancy, it is proposed to constitute a signature which can be used for verifying the adequacy of the chip card for implementing an application. This signature is carried out by a signature machine which prepares a concatenated word including all the data required for producing this signature. Thus it is possible to modify on request the structure of the required signature for an application without having to modify the operational system of the memory chip.
