摘要
采用与传统加密传真通信不同的点对点传输方法,根据传真通信协议的特点,针对商密的特殊要求,对T30通信协议进行改造,研究出一种无中心密钥分配新方法.介绍了通过改造T30通信协议,把对称、非对称密码算法结合到T30协议中;用自定义非标帧进行身份鉴别和起点密钥分发;在C进程采用附加密码算法解决页工作密钥同步等问题.
With the adoption of pointtopoint method for fax encryption communication different from traditional one, the T30 communication protocol according to the specific requirements for purpose of commercial encryption was modified, a new method on basis of centerless key distribution was developed. The modified T30 communication protocol was introduced, which combined symmetric and nonsymmetric encryption algorithm with T30 protocol; verified ID and distributed initial key through nonstandard frame; solved the synchronization of page working key by the additional encryption algorithm.
