Java technology is both a programming language and a platform. The Java programming language originated as part of a research project to develop advanced software for a wide variety of network devices and embedded systems. The goal was to develop a small, reliable, portable, distributed, real-time operating platform. When the project started, C++ was the language of choice. But over time the difficulties encountered with C++ grew to the point where the problems could best be addressed by creating an entirely new language platform. Design and architecture decisions drew from a variety of languages such as Eiffel, SmallTalk, Objective C, and Cedar/Mesa. The result is a language platform that has proven ideal for developing secure, distributed, network-based end-user applications in environments ranging from network-embedded devices to the World-Wide Web and the desktop

S60V2版短信漏洞補丁ortiCleanUp_CurseSMS_103這條不到10個字符短信成功利用了SymbianOS的漏洞，使用者收到這條短信后，就再也無法打開短信收件箱功能，并可能頻繁死機。由于這條短信誰都能發，所以諾基亞所有N系列智能手機、E系列智能手機都將遭遇有史以來最嚴重的安全威脅。目前還沒有發布相關的補丁。如果你尚未中招，建議安裝諾基亞和F-Secure推出的保護程序，直到諾基亞推出新固件為止

VGA彩色信號控制器設計：用VHDL語言編寫程序，重點完成三個功能： 1.棋盤格圖案顯示： 用三基色原理在CRT顯示器上顯示由橫豎八彩條重疊構成的棋盤格圖案； 2.在顯示器上依次顯示0~9十個數字： 每個數字不同顏色，每個顯示大約0.4秒，循環顯示； 3.顯示動畫效果： 將靜態圖像以高頻率顯示，造成動畫效果，最終動態顯示OVER結束。

Spread-spectrum techniques are methods by which electromagnetic energy generated in a particular bandwidth is deliberately spread in the frequency domain, resulting in a signal with a wider bandwidth. These techniques are used for a variety of reasons, including the establishment of secure communications, increasing resistance to natural interference and jamming, and to prevent detec

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2048比特長的密鑰，其他實體使用1024比特的密鑰。 這種算法1978年就出現了，它是第一個既能用于數據加密也能用于數字簽名的算法。它易于理解和操作，也很流行。算法的名字以發明者的名字命名：Ron Rivest, AdiShamir 和Leonard Adleman。但RSA的安全性一直未能得到理論上的證明。

A certification path is an ordered list of certificates starting with a certificate issued by the relying party s trust root, and ending with the target certificate that needs to be validated. Certification path validation procedures are based on the algorithm supplied in ITU-T Recommendation X.509 and further defined in Internet Engineering Task Force (IETF) Request for Comments (RFC) 3280. Certification path processing verifies the binding between the subject distinguished name and/or subject alternative name and the subject public key defined in the target certificate. The binding is limited by constraints, which are specified in the certificates that comprise the path, and inputs that are specified by the relying party. To ensure secure interoperation of PKI-enabled applications, the path validation must be done in accordance with the X.509 and RFC 3280 specifications. This document provides the test assertions and the test cases for testing path validation software against these specifications.

What happens with your machine when you need to move away from the computer for 10 or more minutes? How secure is your data? Can someone sit on your chair while you are at a coworkers office and play with your data? Maybe you need a computer locking tool that is small and easy to use yet powerful enough to make sure your machine is locked when you need to go out for a break.
