Development of a Multifactor-Security-Protocol System Using Ambient Noise Synthesis

Abstract

The escalating cases of security threats on the global scene, especially in the cyberspace, demands urgent need to deploysophisticated measures to mitigate these calamitous threats. To this end, various lock mechanisms have been developedand deployed to prevent access to control systems from potential intruders. This paper provides a solution to this pervasiveproblem, addressing concerns on the physical and virtual components of an access control system. A locally generatedOne-Time-Passkeys (OTPs) was created, leveraging ambient noise as entropy input. The system was deployed on anArduino microcontroller embedded in a safe-cabinet secured with a 12V solenoid lock. The design was implemented andtested against standard metrics. Results achieved include algorithmic optimizations of existing local OTP protocolimplementations, and the realization of a safe lock module, which interfaces with a mobile application developed onAndroid over a secured Bluetooth connection.
