摘要
标签的认证效率一直以来都是影响无线射频识别(RFID)技术广泛应用的一个重要因素,但是目前还没有一个较好的解决方法。在基于树的RFID协议的基础上,通过秘密共享方案将各边的共享密钥分成多份,在保持查找效率的条件下构建了新的密钥树,并设计了基于共享密钥的认证协议。通过分析表明,协议保证较高的认证效率,同时还具有足够的安全性,而且解决了RFID系统研究中长期困扰的密钥更新问题。
The authentication efficiency of tags is always an important factor that restricts the extensive application of Radio Frequency IDentification(RFID).But there is not a good method to solve the problem till now.On the basis of tree-based RFID protocol,this article shared the secret of each path with many portions using the secret-sharing scheme.A new secret tree was created and a secret-sharing-based protocol was proposed while still keeping the searching efficiency.After being analyzed,the protocol is proved to be secure and efficient,and it also solves the key-updating problem which has slowed the study of RFID system for a long time.
