摘要
PGC(Professional Generated Content)需要借助专业摄像机或智能手机等移动终端设备制作媒体内容,面临终端应用可被冒用、媒体内容被篡改等安全风险。文章提出一种面向融合媒体的PGC移动终端安全防护方法,该方法通过融合可信度量和阻断进程Hook技术,保证PGC移动终端运行环境的可信,通过签名验签技术确保PGC APP的接入可信。在真实设备的实验结果表明,论文提出方法在实现对PGC移动终端安全防护的同时,不会给PGC移动终端带来太大的性能开销。
Since PGC (Professional Generated Content) needs to use professional camera or intelligent mobile terminal equipment to make media content, it is facing many security risks where the applications are fraudulent and the media content is tampered so on. This paper presents a security protection method for PGC mobile terminal in convergent media systems, which creates trusted environment in mobile PGC terminal device by exploiting comprehensively trusted measurement technology and Hook-based blocking process technology and ensures the credible access of PGC APP to back-end servers by using the signature verification technology. Experimental results on real mobile terminals show that the proposed method can provide security protection for PGC mobile terminal device and not bring too much performance cost to the mobile terminals
