Secure exchange method between two communications units, control system and server for the set-up of the method

摘要

The method involves generating a private key (K) and a certificate (C) incorporating a public key (P) associated with the private key for a communication unit (T) in response to a reception of a communication request from a communication unit (U) by a server (S). The communication unit (T) executes a cryptographic operation with the private key based on a message (M) received from the unit (U). An Independent claim is also included for a system for controlling exchange of messages between communication units.
