SYSTEM FOR EXCHANGING DATA BETWEEN AT LEAST ONE SENDER AND ONE RECEIVER

摘要

The invention relates to a system for exchanging data between at least one sender (1-5) and one receiver, such as a central server (7), by means of a data transmission network (6) of Internet type, this system comprising means (4, 10) for encrypting/decrypting the data exchanged. The senders and the receiver comprise generators of encryption/decryption keys, which generators are synchronized to generate new keys for message encryption/decryption with each dispatching of a new message from the sender to the receiver.
