An Applied Research On Mimic Defense Application In QR Code Encryption And Physical Access Control

Today is the age of information technology.With the rapid development of information technology,security in cyberspace is a growing problem.The traditional security defense technology can only take effect on the basis of acquiring prior knowledge such as attack characteristics,and cannot effectively deal with unknown security issues such as unknown vulnerabilities and backdoors in the target system.Cyber space mimic defense(CMD)was proposed by Academician Wu Jiangxing and others,is hailed as a revolutionary security defense technology that "changes the rules of the game".The core architecture of CMD is the Dynamic Heterogeneous Redundancy(DHR)architecture.Its endogenous security effects can significantly increase the security and reliability of the target system,making the target system not only effective against attacks from outside the system,but also successfully address potential unknown vulnerabilities,backdoors and other security hazards within the system.At present,as a brand-new defense technology,the specific application of CMD needs to be further researched and developed.The thesis studies the specific application of CMD.The main tasks completed are as follows:(1)A QR code information encryption architecture based on mimic defense was proposed.As an important information carrier,QR code is facing serious security threats such as information leakage and information tampering.This paper proposes a QR code information encryption architecture based on mimic defense to improve the security of QR code.The results of experimental show that the new architecture can greatly improve the security of the QR code,and the identification efficiency is very high,which has application value in practice.(2)A mimic fefense authentication method for physical access control was proposed.The traditional authentication methods of physical access control can not deal with uncertain threats such as unknown vulnerability or backdoor.Thus,we propose a physical access control architecture of an authentication method based on mimic defense,one time password and QR code of mobile phone.The results of experimental show that the new authentication method of physical access control has higher security performance than traditional ones.Meanwhile,the new authentication method can also be used in combination with other authentication methods.
