ABSTRACT:
The invention relates to a method for identifying secret data messages in a one-direction multipoint network. The identifying of the data messages is carried out with the help of identification used for the error check. With the help of the method according to the invention it can be identified to whom or to which group a message is potentially transmitted without increasing the number of bits in the information transmitted and without opening all the secret data messages.
