Abstract

With rapid development of mobile communication, mobile business is becoming one important part of our life. However, the security of mobile business is impacting its wide development. In traditional mobile business based CA, the certificate database is needed to distribute the digital certificate. And it is necessary to query certificate database for getting the public key. In order to solve these problems, an effective ID-based mobile business system is put forward in this paper. In the system, mobile business process is implemented by private key generator (PKG), while traditional mobile business by CA. In the process of verifying signature, the public key of mobile users can be directly computed by their identity without binding their public key and their identity to establish their relations. Moreover, mobile users don't need to access certificate authority, which simplifies the management and distribution of public key, avoids to building certificate database and decreases the cost and the corresponding security risk. Therefore, the ID-based mobile business system is widely used in modern E-Commerce.
一个有效的基于id的移动商务系统
随着移动通信的飞速发展,移动商务正成为我们生活中重要的一部分。然而,移动业务的安全问题正影响着它的广泛发展。在传统的基于CA的移动业务中,需要证书数据库来分发数字证书。为了获取公钥,需要查询证书数据库。为了解决这些问题,本文提出了一种有效的基于id的移动商务系统。在该系统中,移动业务流程由私钥生成器(PKG)实现,传统移动业务流程由CA实现。在验证签名的过程中,无需绑定公钥和身份,即可直接通过身份计算出移动用户的公钥。此外,移动用户不需要访问证书颁发机构,简化了公钥的管理和分发,避免了建立证书数据库,降低了成本和相应的安全风险。因此,基于id的移动商务系统在现代电子商务中得到了广泛的应用。
