基于虎符TePA标准的无线视频安全传输方案研究

Research on a Wireless Video Secure Transmission Solution Based on TePA Standard

针对无线视频传输专网中信息安全保护不足的问题,采用基于TePA标准安全技术构建适合无线视频传输应用的信息安全保护方案。通过对无线视频传输系统现状及存在问题的分析,结合TePA的特点和专网应用的安全需求进行总体方案设计,并针对系统中涉及的密码算法及模式进行比较和选取,结合实际应用进行流程和协议设计,实现一套具有系统架构简单、安全性高、通信系统适应能力强等优势的无线视频安全传输方案。

According to the deficiency of information security in wireless video private network, an information security solution suitable for wireless video transmission applications was established based on Tri-element Peer Authentication（TePA） standard. Based on analyses on the status and some problems in wireless video transmission system, the overall scheme was designed according to TePA＇ characteristics and requirements of private network applications. Encryption algorithms and modes related to the system were compared and selected, and then fl ow and protocol were designed combined with practical applications. Finally, a set of wireless video secure transmission scheme with simple system architecture, high security and strong communication ability was implemented.
