Research on Security Protection Mechanisms for Terminal Devices Throughout Their Lifecycle in Trusted Computing Environments

With the widespread use of the Internet of Things (IoT) and smart terminal devices, security issues regarding terminal devices have become increasingly severe. To address this challenge, this paper proposes a security protection mechanism for terminal devices throughout their lifecycle in trusted computing environments. The mechanism integrates hardware-based root of trust (TPM 2.0) with behavioral analysis technology to design a comprehensive security framework. By introducing TPM for trusted verification during the boot stage and utilizing Intel SGX technology to protect critical data during runtime, this research effectively prevents physical attacks and data tampering. Additionally, a behavior analysis mechanism based on the LSTM model dynamically detects and responds to potential security threats. Furthermore, an identity authentication scheme combined with blockchain technology significantly enhances the security of device authentication. Experimental results show that the proposed security mechanism not only effectively ensures the security of devices but also demonstrates minimal performance overhead, with strong practical application potential.
