摘要
QR码(Quick Response Code)作为重要的信息载体,正面临着严重的信息泄露和信息篡改等安全威胁.本文提出一种基于拟态防御思想的QR码信息加密架构(Mimic QR Code,M-QR),以提升QR码的安全性.首先,基于拟态防御模型的防御原理和特点构建异构冗余的加解密执行体;然后,选调器动态选取若干冗余执行体;接着,表决器对各执行体的处理结果进行表决以获得最终加密信息;最后生成相应的QR码.实验仿真表明,新架构可大幅提高QR码的安全性,而且识别效率很高,具有一定的实际应用价值.
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.Firstly,based on the principle and characteristics of the mimic defense model,a heterogeneous redundancy entities of encryption and decryption is constructed;then,the selector dynamically selects a number of redundant execution entities.Secondly,the voter votes on the processing results of execution entities to obtain final encrypted information.Finally,the architecture generate the corresponding QR code.The experimental simulation shows that the newarchitecture can greatly improve the security of the QR code,and the identification efficiency is very high,which has application value in practice.
