METHOD OF AUTHENTICATION AND SECURE EXCHANGE OF DATA BETWEEN A PERSONALISED CHIP AND A DEDICATED SERVER, AND ASSEMBLY FOR IMPLEMENTING THE SAME

摘要

The method allows authentication and secure wireless data exchange between a chip with an identification code ( 1 ') and a dedicated server ( 35 ) via a read unit ( 5 ). This read unit is arranged for carrying out contactless read and/or write operations on the chip. The read unit is connected to a computer terminal ( 30 ) connected to a communication network ( 300 ) of computer terminals. For the method, a first connection is first of all established to the communication network from the computer terminal connected to the read unit to the dedicated server using a defined secure data communication protocol. A second connection to the communication network from the read unit to the dedicated server is then established. For this second connection, the computer terminal is used as a secure data transmission tunnel in order to directly exchange encrypted data between the read unit and the server in a manner invisible to the computer terminal. Finally, wireless personalised communication can be carried out between the read unit and the chip with an identification code for an encrypted data transfer, once the chip has been able to be identified upon the request, in particular, of the dedicated server.
