LTE network control plane vulnerability analysis method and system based on software radio

The invention provides an LTE (Long Term Evolution) network control plane vulnerability analysis method and system based on software radio. The method comprises the following steps: selecting availability and privacy as indexes for judging LTE control plane security attributes; constructing a privacy attack model and an availability attack model; selecting a mobile device test SIM card for vulnerability analysis and a user server at a core network side, and writing test data; in the attack simulation process, information collection is carried out on the mobile device, the simulation base station and the simulation core network, and state information of the mobile device and signaling information of the core network side are obtained; and carrying out abnormal state judgment to determine whether the availability and the privacy are attacked or not. According to the invention, the potential security vulnerabilities in the LTE network control plane protocol stack can be comprehensively detected and tested. 本发明提出
