Abstract: A process comprises transmitting, by a first device and through a first communication channel, a message comprising an identifier of the first channel, a first encrypted authentication value and at least one encrypted data value, the first authentication value being associated with the first device, receiving, by a second device, the message, decrypting, by a first circuit of the second device, the first encrypted authentication value, applying, by the first circuit of the second device, at least one non-invertible operation on the first decrypted authentication value, resulting in a verification value, comparing, by the first circuit of the second device, the verification value with the identifier of the first channel, and processing the at least one encrypted data value based on the comparison.
