Development of a method for ensuring confidentiality and authenticity in wireless channels

Abstract

The object of the research is the development of a method for ensuring the authenticity and integrity of data in wireless channels based on post-quantum cryptosystems. The development of modern digital technologies ensures the transition to smart technologies and the formation of Next Generation Networks. The formation of smart technologies, as a rule, uses wireless communication channel standards IEEE 802.11X, IEEE 802.15.4, IEEE 802.16, which use only authentication protocols and privacy mechanisms, which are formed on symmetric algorithms. In the conditions of the post-quantum period (the advent of a full-scale quantum computer), the stability of such algorithms is questioned. Such systems, as a rule, are formed on the basis of the synthesis of socio-cyber-physical systems and cloud technologies, which simplifies the conduct of Advanced Persistent Threat attacks, both on the internal circuit of execution systems and on external control systems. The creation of multi-circuit information protection systems allows for an objective assessment of the current state of the system as a whole and the formation of preventive measures to counter cyber threats. The proposed method of providing basic security services: confidentiality, integrity and authenticity based on crypto-code constructions takes into account the level of secrecy of information transmitted over wireless channels and/or stored in databases of socio-cyber-physical systems. The use of post-quantum algorithms – McEliece/Niederreiter crypto-code constructions on elliptic/modified elliptic/lossy/Low-density parity-check code provides the necessary level of stability in the post-quantum cryptoperiod (crypto-stability at the level of 1025–1035 group operations), speed and probability of information (Рerr not lower than 10-9–10-12). The proposed method of information exchange using wireless communication channels ensures their practical implementation on resource-limited devices (creating of CCC on the GF field (24–26).
