METHOD AND SYSTEM MAKING IT POSSIBLE TO TEST A CRYPTOGRAPHIC INTEGRITY OF AN ERROR TOLERANT DATA ITEM

摘要

Method and system for testing the cryptographic integrity of data m comprising at least the following elements a module (1) emitting a message M, said module comprising a memory (2) making it possible to store the parameters used to execute the steps of the method according to the invention, such as the key, the public data, which will be explained hereinbelow, a transmission medium (3), a receiver module (4) also comprising means (5) for storing at least the same parameters as at emission. The system can comprise means (6) for storing confidential data such as the secret keys, a processor (7) suitable for executing the steps.
