Industrial Automatic Control Systems and Controllers Annotation << Back Implementation of the Using of Steganographic Insertions in the Messages Transferred within Industrial LON Networks Kapger I.V., Yuzhakov A.A. The problems of authenticity of industrial LON network messages related to the protection from unauthorized actions are analyzed. The possibility of sender authentication within LonTalk protocol is considered. The communication methods between LonWorks hubs are shown. Possibilities of using steganography are described, restrictions of the algorithm are shown. There were studied the possibilities of using steganographic insertions in the messages communicated in industrial LON networks. The implementation of stream steganography algorithm in language Neuron C in fi rmware of knots constructed on Neuron Chip is suggested.Key words: LON, LonTalk, Neuron C, Neuron Chip, steganography.
