RSA算法是第一個能同時用于加密和數字簽名的算法，也易于理解和操作。RSA是被研究得最廣泛的公鑰算法，從提出到現在已近二十年，經歷了各種攻擊的考驗，逐漸為人們接受，普遍認為是目前最優秀的公鑰方案之一。RSA的安全性依賴于大數的因子分解，但并沒有從理論上證明破譯RSA的難度與大數分解難度等價。即RSA的重大缺陷是無法從理論上把握它的保密性能如何，而且密碼學界多數人士傾向于因子分解不是NPC問題。 RSA的缺點主要有：A)產生密鑰很麻煩，受到素數產生技術的限制，因而難以做到一次一密。B)分組長度太大，為保證安全性，n 至少也要 600 bits 以上，使運算代價很高，尤其是速度較慢，較對稱密碼算法慢幾個數量級；且隨著大數分解技術的發展，這個長度還在增加，不利于數據格式的標準化。目前，SET( Secure Electronic Transaction )協議中要求CA采用比特長的密鑰，其他實體使用比特的密鑰

是一本介紹java基礎應用的好書 Java For Artists targets both the undergraduate computer science or information technology student and the practicing programmer. It is both an introductory-level textbook and trade book. As a textbook it employs learning objectives, skill-building exercises, suggested projects, and self-test questions to reinforce the learning experience. The projects offered range from the easy to the extremely challenging. It covers all the topics you’d expect to find in an introductory Java programming textbook and then some. As a trade book it goes purposefully deeper into topics cut short or avoided completely in most introductory textbooks. Its coverage of advanced GUI programming techniques, network programming and object-oriented theory will enable you to take your skills to a higher level.

The code on this diskette has been organized by chapter. Each subdirectory containing listing has a readme.txt describing program usage and any relevent file formats. The readme will also describe how to compile the target programs under IBM OS/2 (TM) using the using C Set++ compiler (TM). All programs on this diskette have been compiled and tested in this environment. The majority of programs on this diskette should port to other environments with only minor adjustments. The exception to this are those programs which utilize presentation manager for graphical display of program data. In particular, the grid1 programs in \chapt4\backprop\ and \chapt3\ fall into this latter category.

A few short years ago, the applications for video were somewhat confined—analog was used for broadcast and cable television, VCRs, set-top boxes, televisions and camcorders. Since then, there has been a tremendous and rapid conversion to digital video, mostly based on the MPEG-2 video compression standard. Today, in addition to the legacy DV, MPEG-1 and MPEG-2 audio and video com- pression standards, there are three new high- performance video compression standards. These new video codecs offer much higher video compression for a given level of video quality.

FMA is a free1 powerful phone editing tool allowing users to easily manage all of the personal data stored in their phones, via a number of different connections methods. FMA allows easy management of Phonebook (both SIM and Phone memory), SMS, Profiles, and Files stored on the phone. FMA can also allow you to pickup and dial calls directly from your PC. FMA is fun and much more whatever you want it to be, it is whatever a mobile phone should have :-) (Currently based on Sony Ericsson T610 features set).
