Abstract

The invention belongs to the technical field of cognitive radio networks, and discloses a two-way intrusion detection system and method based on cloud computing, and a cognitive radio network, including: initialization, data acquisition, data transmission, data processing, malicious behavior determination, and internal attack determination , attack alerts, malicious user handling. The present invention combines ultra-large-scale cloud computing, dynamic expansion of resources, and massive information processing, and utilizes cloud computing to save the time for agents to traverse the intrusion detection method in a distributed network; according to different attack targets, intelligent agents and cloud servers detect attacks on channels , the secondary node detects attacks against the terminal, simplifies the functions of secondary users and intelligent agents, and saves a lot of communication costs for reporting data to cloud servers; intelligent agents and cloud servers detect the behavior of internal secondary users, which solves the problem of cognitive radio network The problem of possible insider attacks in the

Description

technical field [0001] The invention belongs to the technical field of cognitive radio networks, and in particular relates to a cloud computing-based two-way intrusion detection system and method, and a cognitive radio network. Background technique [0002] Cognitive wireless networks provide an effective solution to the spectrum shortage problem by sensing and utilizing idle spectrum. The new characteristics of cognitive wireless networks also bring new security threats to it, and the existing security mechanisms cannot be directly applied to cognitive wireless networks. Currently, the research on the security of cognitive wireless networks is in its infancy, and research on the intrusion detection mechanism of cognitive wireless networks is an important direction of cognitive wireless network security research. The intrusion detection mechanism can defend the cognitive wireless network from serious security attacks from the perspective of the whole network, and ensure the...
