TECHNIQUE FOR HANDLING DATA IN A DATA NETWORK

摘要

A technique for handling data provided from a source node (120) to a collecting node (130) in a data network (100) is described. As to a method aspect of the technique, the source node (120) generates a sequence of values. The sequence is unrevealed in the data network (100) by the source node (120) in a time interval. An authentication of the sequence is triggered in the data network (100). The authentication associates the sequence with the source node (120). One or more signatures for one or more data sets to be sent in the time interval are computed using one or more values of the sequence. The one or more data sets in the time interval are sent from the source node (120) to the collecting node (130). The source node (120) further provides one or more of the signatures.
