網(wǎng)絡(luò)安全與身份認證技術(shù)的研究與實現(xiàn)

摘要
身份認證就是證實用戶真實身份與其所聲稱的身份是否相符，以防止非法用戶通過身份欺詐訪問系統(tǒng)資源的過程。一次性口令身份認證技術(shù)安全性高、使用方便、管理簡單、成本便宜，具有廣泛的應(yīng)用前景。一次性口令就是在登錄過程中加入不確定因素，使每次登錄傳送的認證信息都不相同，以提高登錄過程安全性。本文設(shè)計了一個一次性口令身份認證系統(tǒng)，對網(wǎng)絡(luò)結(jié)構(gòu)工作流程密碼算法等進行了詳細論述。

Abstract
Identity authentication is a process that is used to approve whether the true identity of user is matched to the identity which the user claims, so that the illegal user can not access the system resource by identity cheat. One time password has good application future because it is secure, convenience in use, simple managed and cheaper cost. By adding uncertain factors to entering course, one time password makes authentication information dynamically at every time, so as to improve the security. A one time password identity authentication system is designed in this paper.
