QR码信息安全研究

Study on Risk Evaluation Method of Security and Protection in Intelligent Community

二维码的广泛应用在给使用者带来便捷的同时,存在着信息被篡改、个人信息泄露等安全隐患。以QR码为例,论述了通用的二维码结构和编码方式,分析了存在的主要安全漏洞。在此基础上,从提高算法加密程度、在解码段增加消息认证、第三方监管等角度提出了应对的策略。

Two-dimensional code is widely used in the market, and brings convenience to users. At the same time, it is faced security problems, such as tampering, personal information leakage, etc. This paper takes the QR code as an example, discusses the general structure and encoding method, analyzes the security problems and loopholes and finally proposes the corresponding solution for these problems from improving the encryption algorithm, increasing the message authentication in decode section and the third party supervision.
