The non-repudiation service ensures that one party cannot deny its involvement in exchanges. This service can take one or two of the forms described below: the first form is non-repudiation with proof of origin, where the recipient receives proof of the origin of the data. This proof may be a digital signature using asymmetric encryption applied to the result of the hashing of the data exchanged. The second form is non-repudiation with proof of the data delivery, where the sender receives this proof in the form of an acknowledgment, for example (ITU-T 1991). The non-repudiation security service is necessary in the IoT to provide proof of data transmission through objects and also as a proof of the dispatch of any order by users of IoT services. This may fit into the framework of an audit that will allow the tracking and recording in trace files of all events that took place in an IoT environment.
