An analysis of technologies to protect a radio channel of fire alarm systems against unauthorized access

Abstract

There is currently a growth of radio fire alarm systems. One of the main disadvantages of such systems is the vulnerability of the communication channel to unauthorized access. Based on the conducted analysis and the apparatus of fuzzy logic, the authors identified the most tamperproof wireless technologies for fire alarm systems to give quantitative assessment of the security level. The most secure technologies to combat complex threats (view, substitution, interception, jamming) include technologies based on noise-like signals (technologies based on random sequences and ultra-wideband signals), while the least secure technologies include cryptographic techniques (simulation protection device). The necessity of further research aimed at enhancing security of the radio channel of fire alarm systems is shown. The development of systems with protection technologies based on noise-like signals is seen as promising
