Abstract
A method for authenticating a central unit communicating with peripheral units performing measurements, using a server device, each peripheral unit generates a shared encryption key, the server device generates a temporary session key and the same shared encryption key, then performs a first encryption in order to form a first shared dynamic encryption key, then performs a second encryption with the identifier of the central unit in order to give an encrypted central-unit information item as proof of authentication transmitted to the peripheral unit, the peripheral unit performs a reverse decryption in order to obtain the temporary session key, and an encryption with the central-unit identifier and the shared encryption key in order to give an encrypted identifier which is compared with the received encrypted central-unit information item in order to grant its authentication.
