摘要
基于BIBA模型,对TCG规范中信任链传递过程中的完整性进行了分析,指出信任链传递写入过程中存在的完整性问题,提出了一种改进的信任链传递模型,实现了系统上电到系统装载过程可信校验和访问控制的方法,有效阻止了恶意代码植入和运行。
Based on BIBA model,the integrity of the software components,which in turn boot during the TCG-standardized system startup,is analyzed.And a writing problem is found.To solve the problem,an improved model is proposed.In the model,the integrity checkout and access control are enforced from the chipset power-on to loading process of the system,so that the implant and execution of malicious codes can be effectively prevented.
