摘　　要：软件可信运行是许多应用领域的基础,但恶意主机问题使得很难保证一个软件可信运行。在传统的基于硬件加密平台保护软件可信运行机制中,运行于安全硬件中的代码和运行于主机中的代码不在同一个执行上下文中,因此难以给用户提供完善的保护策略。为此,提出了一种新的基于安全协处理器保护软件可信运行的框架,在该框架下,软件设计者可以根据待保护软件特点和自身要求定制更加完善和灵活的保护。Trusted execution of program is the basis of many applications. However, malicious host problem makes trusted execution ofprogram difficult. Traditional scheme ofprotecting trusted execution of software based on hardware encryption platform could not provide complete protection policies for software developers, for the code in the secure hardware runs in a different context from the one where the code in the host runs. A new framework of protecting trusted execution of software based on secure coprocessor is proposed. Under the framework, software developers could easily custom more prefect and flexible protection according to the software＇s features and their requirements.
