摘　　要：Dawson E和Chuan-kuan Wu在文[1]中提出了基于广义逆矩阵的密钥协商方案;王永传等、雷信生分别在文[2]、[3]中对其作了补充、改进.作者对以上的密钥协商方案作进一步改进,这样避免了基本的攻击.Dawson E and Chuan - Kuan Wu proposed a theory of key agreements based on generalized inverses of matrices in article [ 1 ]. Wang Yongchuan, et al. and Lei Xinsheng proposed several improvements in articles [ 2 ] and [ 3 ] respectively. Some further modification was made to secure the key agreement against basic attacks.
