【摘要】 为解决传统的口令中存在的许多安全缺陷,人们提出了一次性口令OTP(one tim e password)方案。OTP特别是基于硬件的OTP相对传统口令拥有更强安全性,是未来口令技术的发展方向。但是在应用硬件OTP技术中也带来了使用不便、管理成本上升的问题。通过研究几种典型的基本硬件的OTP技术,结合某ED I项目的具体需求,提出了一个改进的基于硬件的OTP应用方案,并给出了该方案的特点和设计思想。目前,该方案已经投入使用,取得了预期效果。更多还原

【Abstract】 Traditional password has many security flaws.OTP(one time password),especially hardware OTP has much stronger secure ability and has been the future of the password technology.However what accompany the application of OTP is the more complex of the usage and the rising of the management cost.After studying several modals of OTP application and considering the demands of an EDI project,an improved OTP application modal is brought forward.Meanwhile the characteristics and design ideas are also discussed.The running result has proved that the modal fully meets the requirement.更多还原
