Method and device for generating and for validating a digital message and application of such a device

摘要: In this method, a number N is assigned to transmitted and receiving stations comprising synchronous clocks (2), the coded message being obtained by calculating time Tie from elapsed since initialization of clock transmitting station, code Ae1 in accordance with first relationship, Ae2 second M N, Ae2, third relationship. The validation operation performed Tir1 Ar1 received M, Tir1, using Ar2 n highest order bits Ar1, Ae1, Ar3 Tir2 Ar3, Ar4 verifying that equal absolute value difference Tir2-Tir1 less than specified threshold.
