摘　　要：针对多元二次拟群的公钥体制中密钥生成速度较慢的缺点,提出了基于右拟群构造密钥的方法,给出了构造多元二次右拟群的算法。应用该算法可有效地避开巨大搜索空间中的大幅瓶颈区,提高密钥生成速度。In public key scheme based on multivariate quadratic quasigroups, the speed of key generation is very slow. In response to this disadvantage, a new method of key generation based on right quasigroups is pro- posed. Algorithm of generating multivariate quadratic right quasigroups is also given. Application of the algo- rithm can effectively avoid of a significant bottleneck area in the huge search space, and improve the speed of key generation.
