DES( Data Encryption Standard)算法,于1977年得到美國(guó)政府的正式許可,是一種用56位密鑰來(lái)加密64位數(shù)據(jù)的方法。 IDEA是International Data Encryption Algorithm 的縮寫,是1990年由瑞士聯(lián)邦技術(shù)學(xué)院來(lái)學(xué)嘉X.J.Lai 和Massey提出的建議標(biāo)準(zhǔn)算法稱作PES( Proposed Encryption Standard) 。Lai 和Massey 在1992 年進(jìn)行了改進(jìn)強(qiáng)化了抗差分分析的能力改稱為IDEA 它也是對(duì)64bit大小的數(shù)據(jù)塊加密的分組加密算法密鑰長(zhǎng)度為128位它基于“相異代數(shù)群上的混合運(yùn)算”設(shè)計(jì)思想算法用硬件和軟件實(shí)現(xiàn)都很容易且比DES在實(shí)現(xiàn)上快的多。IDEA自問(wèn)世以來(lái),已經(jīng)經(jīng)歷了大量的詳細(xì)審查,對(duì)密碼分析具有很強(qiáng)的抵抗能力,在多種商業(yè)產(chǎn)品中被使用。

英文版,pdf格式。 詳細(xì)說(shuō)明: Title: STL Tutorial and Reference Guide: C++ Programming with the Standard Template Library (2nd Edition) URL: http://www.amazon.com/exec/obidos/tg/detail/-/0201379236/ ISBN: 0201379236 Author: David R. Musser / Gillmer J. Derge / Atul Saini / Gilmer J. Derge Publisher: Addison-Wesley Page: 560 Edition: 2nd edition (March 27, 2001) Catalog: C++ Format: PDF Size: 3.8M Supplier: December Summary: The Standard Template Library was created as the first library of genetic algorithms and data structures, with four ideas in mind: generic programming, abstractness without loss of efficiency, the Von Neumann computation model, and value semantics. This guide provides a tutorial, a description of each element of the library, and sample applications. The expanded second edition includes new code examples and demonstrations of the use of STL in real-world C++ software development it reflects changes made to STL for the final ANSI/ISO C++ language standard.

The standard optimum Kalman filter demands complete knowledge of the system parameters, the input forcing functions, and the noise statistics. Several adaptive methods have already been devised to obtain the unknown information using the measurements and the filter residuals.

This book contains a detailed analysis of the International Standard for the C language,-3.1 excluding the library from a number of perspectives. The organization of the material is unusual in that it is based on the actual text of the published C Standard. The unit of discussion is the individual sentences from the C Standard (2022 of them). Readers are assumed to have more than a passing familiarity with C.

C++ Standard Library provides a set of common classes and interfaces that greatly extend the core C++ language. The library, however, is not self-explanatory. To make full use of its components-and to benefit from their power-you need a resource that does far more than list the classes and their functions. The C++ Standard Library not only provides comprehensive documentation of each library component, it also offers clearly written explanations of complex concepts, describes the practical programming details needed for effective use, and gives example after example of working code.
