针对现有无条件安全密钥协商模型中存在的问题，提出了一种获取初始随机相关信息的新模型。实验结果表明，与现有模型相比，新模型和原信源模型和原信道模型在功能上等价，但新模型在保证合法通信双方之间的误比特率不变的情况下，增加了窃听方的误比特率，弱化了窃听方的优势，提高了密钥协商的总信息率。

To resolve the problems in the unconditionally secure secret key agreement model,a new model to obtain the initial random related information was proposed. The experiment results show that compared with existing models, the new model is equivalent in function to the source model and the channel model. However,in the new model,the bit error rate between legal communication parties remains unchanged, while the bit error rate of eavesdropper increases. Hence,the advantage of eavesdropper weakens and the total information key agreement rate increases.
