Abstract
A method decrypts the encrypted messages sent by a transmission device to a first electronic device associated with a first trusted authority and to a second electronic device. In one embodiment, first and second tokens are generated and exchanged, respectively, by the first and second electronic devices, which then generate a joint decryption key in order to decrypt the encrypted message.
