摘要
二维码作为一种全新的信息存储、传递和识别技术已经在很多领域有着广泛的应用,随着移动互联网和智能手机的快速普及,二维码应用逐渐走进大众的生活。但由于二维码编码算法公开且未实现信息加密,在一些领域存在信息安全隐患。本文通过研究QR码编码规则及加密算法,提出一种结合了RSA和口令的改进算法对编码数据信息加密。解密是加密的逆过程,通过获取正确的私钥输入到专用的识别软件上即可解出明文信息。实验证明,本方法加、解密效率高,安全性好。
As a new information storage, transmission and identification technology, two-dimensional code has been widely used in many fields. With the rapid popularization of mobile internet and intelligent mobile phone, two-dimensional code gradually entered public fife. However, since two-dimensional coding algorithm is open and unencrypted, there is risk to information security in some areas. By studying the QR coding rules and eneryption algorithm, this paper puts forward an improved algorithm which combines the RSA algorithm and password to encrypt information of QR code. Decryption is the inverse of encryption. Once inputting the right pass- word to the special recognition software, the plain information could be obtained soon. The experiments show that using this method to encrypt and decrypt has a good efficiency.
