TZEAMM: An Efficient and Secure Active Measurement Method Based on TrustZone

With the rapid development of computer and communication technology, embedded systems are widely used in smart devices. The increasing connectivity these difficulties providing comprehensive security have made such devices vulnerable to malicious attacks. Passive defense technologies traffic-based intrusion detection not fully effective against Trusted execution environment (TEE) technology can ensure system unknown attacks some extent. Most researchers use TrustZone implement TEE. However, problem is that API interface TEE module which provides service secure. Therefore, actively defend attacks, we developed a trusted computing active measurement architecture based on TrustZone. To overcome serious modules need be passively invoked provide services, proposed an closed-loop immune mechanism. reduce base performance overhead, removed certain functional from environment. In addition, this architecture, trust chain dynamic method target applications. We changed traditional attack response method, requires entire restarted after attack, by developing fallback mechanism more suitable for system. Finally, verified effectiveness model. Performance testing analysis showed reduced impact mechanisms future, will extend our research fine-grained measurements.
