Method of downloading of application parts via distributed systems on to a chip-card, requires provision of secret code or session key by the server prior to loading command-sequence of commands for downloading

摘要

A secret code or session key is made available by the server and a command-sequence of commands is loaded for downloading of the application part on to the chip-card, followed by generating a digital signature with the secret code or session key via each command within the command sequence, and the signed command sequence is then sent as a data packet to the client.
