Abstract: An authentication method is performed between a first party and a second party. The method includes: i) determining a challenge; ii) sending the challenge to the second party; receiving a response from the second party including a second cryptogram; computing a first cryptogram using the challenge and the key of the first party; determining if the first cryptogram matches the second cryptogram received from the second party. If the first cryptogram does not match the second cryptogram, the method further includes performing a computation using the first cryptogram and the second cryptogram; and comparing a result of the computation with a stored set of results to recover a first data element carried by the second cryptogram.

Abstract: Method of controlling an electronic device and corresponding electronic device. The method may be performed by an electronic device (20) and includes steps such as receiving an instruction command (CMD) that includes identifiers (ID) of instructions (IS) that are prerecorded in a memory (30) of the electronic device; using the identifiers to form a code (RC) defining a set of instructions, where the set of instructions combines prerecorded instructions (IS) to execute a security check; and storing the code (RC) in a memory (28) of the electronic device in order to configure the electronic device (20) to execute the security check.

Abstract: A method and apparatus for sending security information are disclosed. The method is performed by a terminal that performs operations, which may include: during a current transaction, receiving first transaction data coming from an electronic device with which the terminal is co-operating; detecting an event encountered by the terminal during the current transaction; generating a transaction message including an indicator indicating that the first data is included in a field of the message; inserting security information in the field of the transaction message as a replacement for the first transaction data, the security information being representative of the event; and sending the transaction message including the security information to a remote server.
