摘要
资源有限,在开放环境中广播信号使得射频识别(RFID)系统存在安全缺陷.在现有的RFID认证协议基础上,基于Hash函数的单调性和不可替换性,提出了一种改进的双向认证协议.改进的协议可以很好地协调安全、高效以及成本问题,在有效避免窃听、追踪、重放等安全威胁上优势明显.
RFID system has many security problems because of limited resource and broadcasting information in an open environment. An improved mutual authentication protocol is put forward in this paper based on existing RFID protocol and Hash function. The protocol can effectively solve the security attacks, such as illegal access, masquerade, etc. It has advantages in balancing the security, efficiency and cost.
