【摘要】：针对移动电子商务关于安全性、高效性的要求,作者总结了基于证书公钥密码机制(Certificate-Based Public-Key Cryptography,CBC)的移动商务方案、基于身份标识密码机制(ID-Based Cryptography,IDBC)的移动商务方案,尤其是基于自验证签名机制(Self-Verified Signature Mechanism,SVSM)的移动商务方案的优缺点,根据前人提出的一系列密码技术、密钥协商机制、身份识别技术,作者提出了一种新型的基于自验证机制的动态对称密钥移动商务方案。新型的移动商务方案采取银行账号信息与唯一身份标识绑定的方式,取代了传统移动商务方案中的虚拟货币;在交易的结尾添加了用户确认机制进一步提高了推荐方案的安全性。并且推荐方案的自验证机制是利用椭圆曲线密码机制(Elliptic Curve Cryptography,ECC)实现的,相比较于传统的RSA公钥加密算法,ECC具有抗攻击性强、计算量小、处理速度快、存储空间占用小、带宽要求低等优点,这就使得推荐方案的自验证效率进一步提高了。作者在分析基于自验证机制的基本算法的基础上,详述了推荐方案完整的身份验证及交易过程,证明了推荐方案的可行性。通过对推荐方案的安全性、高效性的性能分析,我们可以得出结论:本方案在继承、提高了基于自验证机制的移动商务方案的效率的前提下,兼顾了交易的安全性,可以抵挡多种网络攻击,同时在推荐方案的结尾增添了用户确认机制,进一步加强了该方案的安全性。总之,推荐方案较之现行的大部分移动商务方案更有效、更安全、更实用。
[Abstract]:In order to meet the requirements of security and efficiency in mobile electronic commerce, the author summarizes the scheme of mobile commerce based on Certificate based Public-Key Cryptography (CBC) and ID-Based Cryptography IDBC(). In particular, the advantages and disadvantages of the mobile commerce scheme based on the self-verificated Signature MechanismSVSM-based signature mechanism, according to a series of cryptographic techniques, key agreement mechanism, identity identification technology proposed by the predecessors, In this paper, a new dynamic symmetric key mobile commerce scheme based on self-verification mechanism is proposed. The new mobile commerce scheme is based on the binding of bank account information and unique identity. Replacing the virtual currency in the traditional mobile commerce scheme; The user confirmation mechanism is added to the end of the transaction to further improve the security of the recommendation scheme, and the self-verification mechanism of the recommendation scheme is implemented by using Elliptic Curve cryptography mechanism. Compared with the traditional RSA public key encryption algorithm, it has the advantages of strong attack resistance, low computational complexity, fast processing speed, small storage space, low bandwidth requirements, etc. This makes the self-verification efficiency of the recommendation scheme more efficient. Based on the analysis of the basic algorithm based on the self-verification mechanism, the author details the complete authentication and transaction process of the recommendation scheme. The feasibility of the recommendation scheme is proved. By analyzing the security and efficiency of the recommendation scheme, we can draw the conclusion that this scheme can improve the efficiency of the mobile commerce scheme based on self-verification mechanism under the premise of inheriting, improving the efficiency of the mobile commerce scheme based on self-verification mechanism. Considering the security of the transaction, it can resist many kinds of network attacks, and at the same time, it adds a user confirmation mechanism at the end of the recommendation scheme, which further strengthens the security of the scheme. The recommended scheme is more effective, safer and more practical than most of the current mobile commerce schemes.
