摘要
为网络视频会议传输提供有效的通信安全,采用一个会议密钥分配的智能卡系统,来解决使用者身份认证和通信安全问题。在语音和图像方面,分别采用GSM6.10语音压缩和JPEG图像压缩来降低数据量。在智能卡系统内引入多种对称式加密算法以供使用者选择,在多人与会的环境下,利用该智能卡系统来分配一个共同的会议密钥,让与会者可经由这个共同的会议密钥来对资料作加密保护及数字签名。
It presents smart card system of session key distribution for communications safety to net video conference transmission, resolves user identity authentication with security. It adopts GSM6.10 voice and JEPG image compression algorithm in video. It applies multi-symmetry encryption for user selection in smart card system, under many people participation in a conference, utilizes smart card system distribution a common session key, and makes encryption and digital signature for people participate in a conference with the common session key.
