A portable terminal includes a security envelope, the envelope being able to capture a signal transmitted by a generator of the terminal (screen, loudspeaker, etc.), to convey this signal and to restore it at the level of a sensor of the terminal (camera, microphone), so as to be able to detect a breach of this envelope by alteration of the restored signal. A method for securing interactions between devices comprises a step of initial pairing of the devices, said pairing step comprising the transmission of a normal envelope signal for a first device to a second device, (and possibly reciprocally) and a subsequent interaction step between the first and second devices, said interaction step comprising the transmission by the first device to the second device of its current envelope signal, and the verification at the level of the second device that the signal current envelope received from the first device conforms to its normal envelope signal (and possibly vice versa).

Method for determining the origin of fraud in a network of communicating devices where each device has a security envelope and a detector for detecting fraud on this envelope, comprising:
Pairing process between devices at several levels, with a direct pairing (level 0) requiring proximity between devices and an indirect pairing where devices already paired with a second device become indirectly paired (levels 1 and above) with the first device by entourage transfer when the first and second devices are the subject of a direct pairing, and at least certain devices being protected by a secure envelope by a detector for detecting an intrusion of an envelope and for transmitting information envelope breaking to other devices, in which only a device protected by a secure envelope can transmit an environment to another device.
Pairing method between devices capable of transmitting and receiving coding signals transmitted in proximity, a first device transmitting a signal coding a nonce picked up by the second device while simultaneously the second device transmits a signal coding a second nonce picked up by the first device, said nonces being used to generate a common ephemeral symmetric key to secure the exchange between the devices of other data linked to the pairing.
Pairing method between devices capable of transmitting and receiving coding signals transmitted in proximity, a first device transmitting a signal coding a nonce picked up by the second device while simultaneously the second device transmits a signal coding a second nonce picked up by the first device, said nonces being used to reciprocally transmit their public keys to secure the exchange between the devices of other data linked to the pairing.
