Análisis de posibles vulnerabilidades de acceso en entornos de radio cognitiva para entender las falencias de seguridad de esta tecnología, en base a un modelamiento matemático

This paper aims to analyze potential vulnerabilities environments cognitive radio (RRC), because you need to understand what would be the challenges of this new technology to face the level of assurance, the study will focus on the analysis of Byzantine attacks which is a type of attack level link layer that occurs at the time of cooperative monitoring the spectrum, Matlab was used to develop cases modeling research to test different scenarios using radio spectrum, based on a established by equation, to understand how malicious users can use the RRC to carry out attacks from the child nodes and generate false reports of use of the medium. In applying the model was observed that indeed the likelihood of attack increases up to 99% by increasing the number of rogue users and taking into account a range of probability of lying of those users from 70% to 100%, this shows the serious security flaws in that environment reports for case detection licensed users, on the other hand that probability varies at a rate of 0% to 30% if we take into account the number of malicious users M involved in communication.
