【摘要】：隨著移動支付技術(shù)的普及,人類的日常生活變得方便快捷,通信和購物不再受到地點及時間的限制,移動支付的前景因此變得廣闊。但在數(shù)字簽名和移動支付協(xié)議方面,仍存在著安全性低和效率低的問題,針對以上問題,本文提出了改進的數(shù)字簽名算法和基于密鑰協(xié)商的移動支付協(xié)議。具體工作內(nèi)容如下：(1)提出了一種對橢圓曲線數(shù)字簽名算法(Elliptic Curve Digital Signature Algorithm, ECDSA)的改進算法,通過大量的對比實驗,得出如下結(jié)論：本方案提高了數(shù)字簽名算法的性能,并且降低了算法的計算復雜度,可以幫戶移動端的用戶更好的保護自己的隱私信息,防止惡意攻擊者盜取、破壞移動用戶的通信信息。(2)提出了一種基于擴展的Chebyshev混沌映射的密鑰協(xié)商協(xié)議,新協(xié)議包含三個組成部分用戶Ui,注冊中心RC和服務(wù)器S。和其他協(xié)議相比,新協(xié)議包含對稱加密、公鑰加密、Chebyshev映射和哈希函數(shù)等算法,能夠保證協(xié)議的安全性。(3)提出了一種基于密鑰協(xié)商協(xié)議的移動支付協(xié)議,該協(xié)議基于對稱密鑰體制,在無線網(wǎng)絡(luò)環(huán)境中適用。在本協(xié)議中,用戶不需要進行大量的關(guān)于密鑰的運算。通過對比實驗,得出如下結(jié)論：本協(xié)議能夠有效保證客戶的隱私和交易信息的安全,充分的保證了支付協(xié)議中的各方安全需求,具有實際應用的價值。
[Abstract]:With the popularity of mobile payment technology, the daily life of human become convenient and fast, communication and shopping are no longer limited by location and time, so the prospect of mobile payment becomes broad. However, in the aspect of digital signature and mobile payment protocol, there are still some problems such as low security and low efficiency. In view of the above problems, this paper proposes an improved digital signature algorithm and a mobile payment protocol based on key agreement. The main work is as follows: (1) an improved algorithm for elliptic curve digital signature algorithm (Elliptic Curve Digital Signature Algorithm, ECDSA) is proposed. Through a large number of comparative experiments, the following conclusions are drawn: this scheme improves the performance of the digital signature algorithm. And reduce the computational complexity of the algorithm, can help mobile users to better protect their own privacy information, prevent malicious attackers steal, This paper proposes a key agreement protocol based on extended Chebyshev chaotic mapping. The new protocol consists of three components: user UI, registry RC and server Sid. Compared with other protocols, the new protocol includes symmetric encryption, public key encryption Chebyshev mapping and hash function, which can guarantee the security of the protocol. We propose a mobile payment protocol based on key agreement protocol. The protocol is based on symmetric key system and can be used in wireless network environment. In this protocol, users do not need to perform a large number of key operations. Through comparative experiments, the following conclusions are drawn: this protocol can effectively guarantee the privacy of customers and the security of transaction information, and fully ensure the security requirements of all parties in the payment protocol, which is of practical application value.
