报告摘要:Cellular networks bring us great convenience by allowing us to access networks any time anywhere. The convenience, however, suffers from design and logic flaws in network protocols, which exposes various security problems both to users and service providers. Many research efforts have been proposed to identify flaws in cellular network protocols, but most of them involve a lot of manual work. In this talk, an automated framework based on formal method for specifying and verifying cellular network protocols (CellScope) is proposed. In particular, CellScope consists of two parts: a parser frontend and a verification backend. The frontend automatically translates LTE source code to formal models and optimizes models by our property-driven slicing mechanism to reduce state space. In the backend, a counterexample guided sparse value flow analysis mechanism is proposed to enhance the accuracy of model checking. CellScope has been evaluated with an open-source LTE network software (over million lines of code) and identified several known and unknown vulnerabilities. These found vulnerabilities have been validated with real LTE simulators and phones.
