Research on Authenticated Secret Key Agreement Protocol withSelf-signed Implicit Certificate
摘要
Abstract
As well known,among all the information security requirements in Internet of Things (IoT) network,user authentication and data transmission confidentiality both are the most essential.However,edge devices in IoT are commonly distributed,and most of them are unattended,so it has become pressing to create an end-to-end security mechanism to secure the information transmission in IoT.Considering the confinations of devices in IoT network are bandwidth,computing power and memory limit,the IoT nodes cannot support heavy security protocol.In order to solve the above problems,a new authenticated key agreement protocol based on ECQV (Elliptic Curve Qu-Vanstone) self-signed implicit certificate has been introduced,which is based primarily on ECQV self-signed certificate generation scheme and ECQV self-signed implicit certificate public key extraction scheme and can perform mutual authentication between the user and node,with smaller footprint and higher authenticate efficiency.This proposed protocol programmed with C language run by Contiki operation system has been tested and evaluated with WiSMote nodes.Experiment results show that the ECQV certificate is smaller than traditional certificate,and thus the system bandwidth has been reduced as well as the time and energy consumption.In general the proposed protocol can be deployed on resource-constrained devices in IoT,and with better secure performance.关键词
