【摘要】：現如今,隨著移動電子商務界的快速發(fā)展,與互聯網相關的許多服務例如股票交換、網上購物和銀行業(yè)務逐漸成為人們生活中不可缺少的部分,消費者大多采用網上支付的方式,而電子優(yōu)惠券的出現,無疑為消費者群體帶來便捷的優(yōu)惠,電子優(yōu)惠券的種類繁多,越來越多的人在購物時都會使用電子優(yōu)惠券,但隨之而來的是網絡信息安全問題日趨嚴重,目前已發(fā)生很多起盜取私人信息及財務的事件,因此人們廣泛研究認證方案及密鑰協商協議。本文主要針對電子優(yōu)惠券環(huán)境下的網絡安全問題進行了深入的研究,提出了基于生物識別技術的一次性口令認證方案,采用生物識別認證技術與一次性口令相結合的方式,搭建了電子優(yōu)惠券環(huán)境下的網絡密鑰協議。首先通過對基本理論知識的簡單介紹,我們知道了生物識別技術有著唯一性與不可替代性的特點,且生物特征的采集成本極低,一次性口令使得用戶在登錄過程中加入了更多不可預知的因素,利用哈希函數構建密鑰,避免許多消耗算法,這樣就為消費者的身份識別與認證提供了巨大的安全保障,有效的防止了攻擊者通過各種非法途徑的攻擊,實現高可靠性、高效率的電子優(yōu)惠券系統(tǒng)。本文對該密鑰協議的各個環(huán)節(jié)進行了重點說明、詳細的給出算法步驟,包括電子優(yōu)惠券用戶的注冊階段、電子優(yōu)惠券的發(fā)行階段、電子優(yōu)惠券的下載階段、一次性口令更新階段,然后給出安全性分析以及效率分析,最后總結電子優(yōu)惠券環(huán)境下的密鑰協議并對該網絡密鑰協議進行展望。
[Abstract]:Nowadays, with the rapid development of mobile e-commerce, many Internet-related services such as stock exchange, online shopping and banking have become an indispensable part of people's lives. Consumers mostly pay online, and the emergence of electronic coupons undoubtedly brings convenience to consumers. There are a wide variety of electronic coupons, and more and more people will use electronic coupons when shopping. However, the problem of network information security is becoming more and more serious. At present, there have been many incidents of theft of private information and financial resources. Therefore, the authentication scheme and key agreement protocol are widely studied. In this paper, a one-off password authentication scheme based on biometrics is proposed, which focuses on the network security in the electronic coupons environment. The network key protocol under the environment of electronic coupons is constructed by combining biometric authentication technology with one-off password. Firstly, the basic theoretical knowledge is briefly introduced. We know that biometric technology has the characteristics of uniqueness and irreplaceable, and the cost of biometric acquisition is very low. The one-time password makes users add more unpredictable factors to the login process. By using hash function to construct key and avoid many consuming algorithms, it provides huge security for the identification and authentication of consumers, effectively prevents attackers from attacking by various illegal ways, and achieves high reliability. This paper focuses on each link of the key protocol, and gives the algorithm steps in detail, including the registration stage of electronic coupons users, the issuing stage of electronic coupons. The downloading stage of electronic coupons, the one-off password updating stage, and the security analysis and efficiency analysis are given. Finally, the key protocol under the environment of electronic coupons is summarized and the network key protocol is prospected.
