基于TCM的可信摄像头设计

Design of trusted camera based on TCM

以普通摄像头为例,创新性地将可信计算技术应用到摄像头系统中。基于国产可信密码模块TCM,以可信链思想为依托,全程保障服务端、传输过程以及客户端的安全。通过由底至顶,兼顾软、硬件,层层度量的方式来确保摄像头的数据安全与行为可控。该可信摄像头运行在Linux环境下,基于可信框架CUBE与TCM模拟器,同时配合我国自主研发的国密算法,初步实现了可信技术在摄像头上的应用。此外,目前可信计算技术在物联网上尚未有实际落地应用,因此可以认为,该设计将是基于国产可信计算生态圈,扩展可信计算应用范围的一次重要尝试。

Taking the ordinary camera as an example,this paper innovatively applies the trusted computing technology to the camera system.Based on the domestic trusted cryptography module TCM,relying on the idea of trusted chain,it guarantees the security of the server,the transmission process and the client.Through bottom to top,taking into account software and hardware,and taking measures layer by layer to ensure the data security and controllable behavior of the camera.The trusted camera runs under the Linux environment,based on the trusted framework CUBE and TCM simulator,and cooperates with the state-secret algorithm independently developed in China,and initially realizes the application of trusted technology in the camera.In addition,trusted computing technology has not been applied in the Internet of Things.Therefore,we believe that this design will be an important attempt to expand the application scope of trusted computing based on the domestic trusted computing ecosystem.
