摘　　要：为完善目前NFC点对点模式的漏洞,设计出一套全新的传输认证协议。采用着色Petri网进行理论建模,查找并论证安全风险的存在。通过融合多种已有的优秀算法,结合设备实际,给出全新的加密及认证方法,生成基于近场通信协议栈的安全隧道,并从算法复杂度的角度分析改进后协议的安全性。新协议能够抵御针对近场通信的多种攻击方式,稳健运行的同时更有着良好的应用前景,在安全上予以更高层次的保证,真正实现"碰一碰"即可完成交互的目标。To plug the holes in the NFC peer to peer mode,this paper designs a new protocol for the transmission and authentication. The paper uses the simulation of the CPN which can find and demonstrate the existence of security risks to make theoretical modeling. Through combining several existing excellent algorithms with the practical facilities,it can give out a completely new encryption and authentication method which can develop a security tunnel based on NFC protocol stack. It also analyses the security of the improved protocol from the perspective of the complexity of the algorithm. The new protocol can be well resistant to many attack modes of NFC,executing stably and having good prospect.It can also grant a guarantee of higher level, truly realizing the goal of interactivity just through'touching'.
