We mainly simulate a process of online emerce payment . At the same time, we explore the design method for a asynchronous design in order to deal with the high concurrency processing as well as the technology for ensuring security during the online emerce transactions. The paper described the basic ponents of electronic payment interface. With a simple model of the Secure transactions , we refer to two main areas of online payment interface: business platform and thirdparty trading platform designed and Simulation. Finally, by integrated with the PHP framework, we achieve the data log print and database transaction handling. After system testing, the program successful simulates data transmission between the electronic trading of online payment interface . In this paper, the program development process is mainly related to the following technologies: Digital abstract generated MD5 algorithm Signatures and digital signatures for verifying the signature, the use of PHP39。s CURL extension, APACHE server virtual host configuration, LINUX daemon task settings, MYSQL database transaction mechanism. By anizing these technologies rationally, we realize transactionbased model of electronic transactions in dealing with the online payment interface with high concurrency capabilities . Key words： digital signature。 asynchronous。 transaction mechanism。 1 目 錄 第一章 緒論 ............................................................................................................... 1 選題背景 ........................................................................................................... 1 當(dāng)前技術(shù)狀況 .................................................................................................... 1 加密技術(shù) ................................................................................................. 2 簡單的安全消息系統(tǒng) ................................................................................ 2 交易協(xié)議 ................................................................................................. 4 內(nèi)容安排 ........................................................................................................... 9 第二章 相關(guān)技術(shù)介紹 ............................................................................................... 10 開發(fā)環(huán)境 ......................................................................................................... 10 硬件設(shè)備 ............................................................................................... 10 軟件環(huán)境 ............................................................................................... 10 相關(guān)技術(shù) ......................................................................................................... 10 數(shù)字簽名 ............................................................................................... 11 數(shù)字證書 ............................................................................................... 12 事務(wù)機(jī)制 ............................................................................................... 14 守護(hù)進(jìn)程 ............................................................................................... 15 本章總結(jié) ......................................................................................................... 15 第三章 模型分析 ...................................................................................................... 16 性能分析 ......................................................................................................... 16 安全性分析 ..................................................................................................... 16 第四章 設(shè)計(jì) ............................................................................................................. 17 總體設(shè)計(jì) ......................................................................................................... 17 數(shù)據(jù)庫設(shè)計(jì) ..................................................................................................... 19 商戶平臺(tái)設(shè)計(jì) .................................................................................................. 21 支付平臺(tái)設(shè)計(jì) .................................................................................................. 23 后臺(tái)腳本程序設(shè)計(jì) ........................................................................................... 24 第五章 實(shí)現(xiàn) ............................................................................................................. 25 系統(tǒng)配置 ......................................................................................................... 25 商戶平臺(tái) ......................................................................................................... 25 支付平臺(tái) ......................................................................................................... 26 守護(hù)進(jìn)程 ......................................................................................................... 27 系統(tǒng)測試 ......................................................................................................... 28 第六章 總結(jié) ............................................................................................................. 30 論文總結(jié) ......................................................................................................... 30 前景展望 ......................................................................................................... 30 參考文獻(xiàn) ........................................................................................................................ 31 附錄 ................................................................................................
