摘　　要：击键韵律是以人的行为特征为基础的身份认证技术。文章对PR-RP算法模型进行分析,参照PR-RP模型中四个关键的数据集,重新构建P-P时延数据集和R-R时延数据集。然后,在电话收音机业务平台的基础上,通过UML对需求进行详细分析,绘制分析类的行为顺序图。最后,基于重构的PR-RP模型设计较为灵活的口令鉴别增强系统。该系统充分考虑功能和安全方面的要求,可以无缝嵌入到实际商用系统中。Keystroke rhythm is an identity authentication technique which takes persons behaviour characteristics as the basis. The PR-RP model is analyzed, in which four critical dataset are chosen, P-P and R-R relay dataset are rebuilt and processed. And then, the telephone radio set business platform＇s request is analyzed by means of UML The act sequence sketches of the analysis classes are completed. Finally, Password authentication system has designed based on the restructuring PR-RP model. The system has fully considered the request about function and security and may seamlessly insert to the actual commercial system.
