摘要
广播电视信号传输中的安全保障技术是确保节目安全播出的关键。针对信号传输过程中面临的安全威胁,分析主流的信号加密技术、条件接收系统(Conditional Access System,CAS)技术和数字版权管理(Digital Rights Management,DRM)技术等核心技术的特点及应用效果。通过深入分析各项技术的优势和局限性,提出基于分层加密和智能卡认证的安全保障技术方案,为提升广播电视信号传输安全水平提供技术支撑。
The security technology in broadcasting and television signal transmission is the key to ensuring the safe broadcast of programs.Analyze the characteristics and application effects of core technologies such as mainstream signal encryption,Conditional Access System(CAS),and Digital Rights Management(DRM)in response to security threats faced during signal transmission.By deeply analyzing the advantages and limitations of various technologies,a security protection technology solution based on layered encryption and intelligent authentication is proposed to provide technical support for improving the security level of broadcasting and television signal transmission.
