云計算服務保障體系

云計算是一種商業(yè)計算模型，它將計算任務分布在大量計算機構成的資源池上，使用戶能夠按需獲取計算能力、存儲空間和信息服務。與以往的計算模式不同，云計算環(huán)境下，信息安全和服務保障問題更嚴重、更突出。本書從云計算的安全技術和服務質量評價兩個方面論述云計算服務保障的體系架構，安全技術方面主要闡述了基于可信計算的實時度量、基于角色的數(shù)據(jù)隔離訪問、云節(jié)點信任鏈的動態(tài)維護模型與驗證機制和多級安全訪問控制模型；服務質量評價方面提出基于動態(tài)篩選評價指標的云服務QoS模型（CSERVQUAL）和改進TOPSIS的云服務QoS評價方法（IEC-TOPSIS）。本書適合開發(fā)、維護和使用云計算服務的人員閱讀，可以作為云計算研究人員的參考書，也可以作為計算機與信息安全相關專業(yè)高年級本科和研究生階段教材。

算法設計與分析

為了便于讀者進行系統(tǒng)學習、分類整理知識點及遇到問題時能夠快速找到求解的方法，本書按照算法策略進行劃分，每一章都引入了若干個經(jīng)典問題。通過問題的分析、計算模型的建立、算法的設計與描述、算法的分析來深入解讀每一種算法策略所能解決的問題范疇及方法。全書共分9章，內容包括：算法設計基礎、算法效率分析基礎、迭代法、蠻力法、分治策略、回溯與分支界限、貪心算法、動態(tài)規(guī)劃、隨機算法。本書非常注重教材的可讀性和實用性，以問題分析→模型設計→算法設計描述→算法分析為技術線路，幫助讀者迅速掌握算法設計要點，規(guī)范算法設計、分析及實現(xiàn)的方法。書中例題的問題分析和模型設計模塊用于培養(yǎng)讀者的抽象設計能力，算法設計模塊用于提高讀者運用計算機求解問題的能力，算法分析模塊用于幫助讀者運行用數(shù)學工具對算法進行客觀分析。同時，本書編寫時也考慮到初學者所面臨的困難，在算法設計與描述中，刻意增加了基于源代碼的程序設計與實現(xiàn)環(huán)節(jié)，從而全方位地幫助讀者提高算法設計與分析實踐能力和理論水平。
