Attacks to Cryptography Protocols of Wireless Industrial Communication Systems

Abstract

The paper deals with problems of safety and security principles within wireless industrial communication systems. First safety requirements to wireless industrial communication system, summarisation of attack methods and the available measures for risks elimination are described with orientation to safety critical applications. The mainly part is oriented to identification of risks and summarisation of defensive methods of wireless communication based on cryptographic techniques. Practical part the cryptoanalytic’s attacks to COTS (Commercial Off-The-Shelf) wireless communications are mentioned based on the IEEE 802.11 standards.
