【摘要】：針對(duì)移動(dòng)電子商務(wù)關(guān)于安全性、高效性的要求,作者總結(jié)了基于證書(shū)公鑰密碼機(jī)制(Certificate-Based Public-Key Cryptography,CBC)的移動(dòng)商務(wù)方案、基于身份標(biāo)識(shí)密碼機(jī)制(ID-Based Cryptography,IDBC)的移動(dòng)商務(wù)方案,尤其是基于自驗(yàn)證簽名機(jī)制(Self-Verified Signature Mechanism,SVSM)的移動(dòng)商務(wù)方案的優(yōu)缺點(diǎn),根據(jù)前人提出的一系列密碼技術(shù)、密鑰協(xié)商機(jī)制、身份識(shí)別技術(shù),作者提出了一種新型的基于自驗(yàn)證機(jī)制的動(dòng)態(tài)對(duì)稱密鑰移動(dòng)商務(wù)方案。新型的移動(dòng)商務(wù)方案采取銀行賬號(hào)信息與唯一身份標(biāo)識(shí)綁定的方式,取代了傳統(tǒng)移動(dòng)商務(wù)方案中的虛擬貨幣;在交易的結(jié)尾添加了用戶確認(rèn)機(jī)制進(jìn)一步提高了推薦方案的安全性。并且推薦方案的自驗(yàn)證機(jī)制是利用橢圓曲線密碼機(jī)制(Elliptic Curve Cryptography,ECC)實(shí)現(xiàn)的,相比較于傳統(tǒng)的RSA公鑰加密算法,ECC具有抗攻擊性強(qiáng)、計(jì)算量小、處理速度快、存儲(chǔ)空間占用小、帶寬要求低等優(yōu)點(diǎn),這就使得推薦方案的自驗(yàn)證效率進(jìn)一步提高了。作者在分析基于自驗(yàn)證機(jī)制的基本算法的基礎(chǔ)上,詳述了推薦方案完整的身份驗(yàn)證及交易過(guò)程,證明了推薦方案的可行性。通過(guò)對(duì)推薦方案的安全性、高效性的性能分析,我們可以得出結(jié)論:本方案在繼承、提高了基于自驗(yàn)證機(jī)制的移動(dòng)商務(wù)方案的效率的前提下,兼顧了交易的安全性,可以抵擋多種網(wǎng)絡(luò)攻擊,同時(shí)在推薦方案的結(jié)尾增添了用戶確認(rèn)機(jī)制,進(jìn)一步加強(qiáng)了該方案的安全性。總之,推薦方案較之現(xiàn)行的大部分移動(dòng)商務(wù)方案更有效、更安全、更實(shí)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.
