Abstract
A process for establishing secure communication between particular communicating units via a channel of a telecommunication network encodes data embodying information to be selectively transmitted from a transmitter unit to one or more particular receiver units prior to transmission using an error detecting code enabling reliable recovery of the information on reception. For security reasons, the error detecting code used to encode the information is encrypted using an enciphering key defined by application of a time dependent variation law. Alternatively, the error detecting code used to transmit information can be selected by application of a time dependent variation law.
