窄带物联网下的安全门锁密钥可靠更新方案
|
摘要
在窄带物联网(Narrow Band Internet of Things,NB-IoT)通信系统中,设备间的数据通信以无连接的UDP(User Datagram Protocol)报文方式传输。在不可靠的UDP传输机制下,密钥的可靠更新成了安全门锁机制研究中的难点。文中设计了一个无连接通信链路上的密钥可靠更新方案,该方案利用智能门锁密钥更新的特点,通过精心设计的密钥传输交互机制,使门锁设备通过UDP协议获取密钥并且可靠地完成密钥更新。理论分析和原型实验的结果表明,该方案能够可靠地更新密钥,并具有较小的通信开销和计算开销。
In narrow band internet of things communication system,the data among devices are transmitted by connectionless UDP protocol.Based on the unreliable UDP protocol,it is difficult to reliably update the keys for the security door system.This paper designed a reliable key updating scheme over connectionless communication link.This scheme makes use of the characteristics of smart lock key updating,and adopts the carefully designed interactive key transmission mechanisms,so as to make lock devices get keys by UDP protocol and achieve key updating reliably.Theoretical analysis and prototype experiment results show that the proposed scheme holds small communication and computation overhead while reliably updating the key.
