摘要
NGB智能电视操作系统(NGB TVOS)是广电实现终端标准化、智能化的关键技术,而安全可控是NGBTVOS的重点研究内容。本文详细介绍了TVOS采用的应用签名方案,通过开发者自签名、运营商签名、多级证书结构等手段共同保证了TVOS应用安装的数据完整和来源可靠,可有效阻止未授权、未认证的应用在TVOS上安装使用。
NGB TVOS is a key technology to realige TV terminals＇ standardization and intellectualization. Safe and controllable are the key research content for the technology. This paper discusses in detail the Apps signature scheme adopted by NGB TVOS. To ensure TVOS Apps integrity and source reliability, developer signature, operator signature and multi- certificates are used. The technical proposal can effectively prevent the installation of illegal application.
