摘要：A method and/or system for transmitting sequences of signals/data from atransmitter to a receiver and for authenticating the sequences of signals/data mayconsist of a precalculation phase and of a communication phase in which the signals aretransmitted together with the checking sums. In the precalculation phase, a pseudo-
random sequence may be first generated by means of a cryptographic algorithm from atime-variable parameter and other initialization data. Non-overlapping sections (z() of asequence (z) having each m bits may be associated to signals (s(i)), wherein i=1, 2, . . . n, ofa signal storage. Further non-overlapping m bit sections (t(i)) of the remaining sequencemay be selected for coding numbers (1, 2, . . . MAX). The transmitter may transmit theinitialization information and the time-variable parameters to the receiver and thereceiver may calculate the pseudo-random sequence (z) and checks the receiverauthentication token (T). The transmitter may accept the received signals as beingauthentic when the received authentication tokens match the calculated ones.
