摘　　要：目前在电子商务中主要采用序列号形式的电子消费券,信息容量小且安全性差。为解决该问题,将PKI与二维条码技术相结合,提出一种新型二维条码电子消费券及其使用流程和系统架构,该电子消费券的创建过程为:将原始的消费券信息利用PKI技术进行签名和加密后,再利用Base64编码进行字符编码,最后利用二维条码技术生成二维条码图像形式的电子消费券。实验证明,相比现有技术,该电子消费券信息容量大,数据安全且来源可靠,并可以支持离线使用,适用于团购等新的电子商务模式。Currently serial numbers are the most commonly used electronic vouchers for e-commerce,which can not store information and have bad security.This paper proposed a PKI and 2D barcode based electronic voucher,as well as the proces-sing flow and system architecture for supporting its applications.The generation process included three steps：the first step signed and encrypted the original voucher data using the PKI technology.The second step mapped the encrypted data to Base64 characters.Finally the characters were coded to a 2D barcode image with a 2D barcode algorithm.Experimental results prove that compared with the existing technologies,the new electronic voucher has more data capacity and security,and supports offline use,which is suitable for new e-commerce models such as group purchase.
