摘要
可信计算技术SGX通过隔离出一块可信执行环境,来保护关键代码及数据的机密性与完整性,可以帮助防范各类攻击。首先,介绍了SGX的研究背景和工作原理,分析了SGX在可信计算领域的研究现状。然后,整理了SGX当前的应用难点和解决办法,并与其他可信计算技术进行了对比。最后,探讨了SGX技术在可信计算领域的发展方向。
The trusted computing technology SGX protects the confidentiality and integrity of key codes and data by isolating a trusted execution environment,which can help prevent all kinds of attacks.Firstly,the research background and working principle of SGX were introduced,the research status of SGX in the field of trusted computing were analyzed.Then,sorted out the current application difficulties and solutions of SGX were sorted out and compared with other trusted computing technologies.Finally,SGX technology development direction in the field of trusted computing was discussed.
