摘要
针对QR码存在的安全性不足的缺点,本文通过研究QR码编解码规则和加密算法,提出利用PBE算法对QR码中信息进行加密。编码时在QR码中加入加密标志位,输入口令并用PBE算法对信息加密。解码时采用开发的专用识别软件输入正确口令即可解密出明文信息。实验表明,本方法可大幅提高QR码的安全性,具有很强的实用性。
Though research on the encode/decode rules of QR Code and encryption algorithm,the paper put forward a method that PBE algorithm was used to encrypt information of QR Code.When encoding a barcode,Encryption Mark Bit was put into QR Code;then the information was encrypted by using PBE algorithm with a password.The barcode could be decoded by using the private decoder and inputting the right password,the plain information could be get soon.Experiments showed that this method could improve the security of QR Code remarkable and also had strong practicability.
