Title: COMMUNICATION SYSTEM AND METHOD FOR COMMUNICATING BY MEANS OF A SEQUENCE OF TELEGRAMS
Abstract:
The invention relates to a communication system for communicating a sequence of telegrams, comprising at least one communication means for establishing a connection and for establishing a sequence of check values, which can each be determined from a payload data part of the telegram, and for establishing an initial value, wherein at least one communication means has a function for determining the initial value (10), and wherein, in the case of a first connection establishment, the sequence of check values (11) was generated at least with consideration of an old initial value, wherein, in the case of a second connection establishment by restarting the communication, the function generates an initial value (10) different from the old initial value such that the initial value (10) is, with high probability, different from the old initial value that was last used. The invention further relates to a method for communicating a telegram.
