  • Patent number: 6052783
    Abstract: A method of loading commands (C1, C2, . . . ) in a security module (2) of a terminal (1) is disclosed. The method comprises the steps of: a station (4) transferring the commands (C1-Cn) to the terminal (1), the terminal (1) transferring the commands (C1-Cn) to the security module (2), the security module (2) executing the commands (C1-Cn), the terminal (1) selectively recording actual results (R1'-Rm') of the executed commands (C1-Cn), and the transfer means (3) transferring the results (R1'-Rm') back to the station (4). The commands may have associated expected results (e.g. R1), which the terminal (1) may compare with the actual results (e.g. R1' ). This allows both a flexible loading of data in the security module (2) by means of commands and a remote check of the functioning of the security module.
