Analysis of protection technologies radio fire alarm systems against unauthorized access

Abstract

There is currently a growth of radio channel fire alarm. One of their main disadvantage is the vulnerability of the communication channel to the data being compromised. The authors, based on our analysis and fuzzy logic unit, identified the most tamper-proof wireless technology fire alarm to give a quantitative evaluation of the security level. The most secure technologies from complex threats (view, substitution, interception, jamming) include technologies based on spread-spectrum signals (based on the technology of random sequences and ultra-wideband signals) and are the least secure cryptographic techniques (simulation protection device). It's the necessity of further research aimed at improving the security of the radio fire alarm. A promising development is seen systems with technologies to protect the radio channel based on spread-spectrum signals (based on the technology of random sequences and ultra-wideband signals).
