说明：  基于AES和RSA加密算法的RFID安全机制 考虑到对国内应用最广泛的Mifarel系列标签的安全手t一级， 在建立以 MFRC500为读卡核心的RFID读卡系统的基础上，提出了一种基于非 对称加密与对称加密算法相结合的RFID安全机制。利用一1卜对称力11密算法对对称 加密算法的密钥的二次加密，做到只有特定的读写器才能拥有读写卡的权利。该 安全机制跳过RFID在开放环境中传输所面临的各种威胁，通过利少月安全性和稳 定性久经考验的公开安全加密算法对存入智能卡信息的重加密，解决了RFID所 面临的安全和隐私泄露问题 (Taking into account the most widely used domestic Mifarel series of labels t a safe hand, In the establishment of MFRC500 as the reader, RFID reader system, the core was proposed based on a based on non- Symmetric encryption and symmetric encryption algorithm is a combination of RFID security mechanism. The use of a one-Bu symmetry edge 11 close to the symmetric algorithm The key encryption algorithm for re-keying, so that only certain card reader in order to have the right to read and write. The Skip RFID security mechanisms to transfer in an open environment faced by a variety of threats, through the pros on the security and stability Qualitative time-tested public security encryption algorithm into the smart card information, re-encryption, solved by RFID Faced with the problem of security and privacy leaks)

说明：  鉴于语音信号的“即时性 ”特点 ,在分析了混沌掩盖、混沌调制进行加密利弊的基上 ,构造了一种混沌切换加密方案 ,对语音进行了更安全有效地加密.(DESIGNOFVOICEENCRYPTIONCOMMUNICATIONSYSTEMBASEDONCOMPUTERNETWORK)

主流的32位MD5加密算法在.NET2003平台上的实现（WINFORM模式）例子，如果你希望给自己的项目加入安全机制但却对MD5加密未曾接触，那可能这个例子可以给你一点帮助(mainstream 32 MD5 encryption algorithm.NET2003 platform achievement (WINFORM mode) example, if you want to own the item by adding security mechanisms but right MD5 encryption has not been exposed to, That may be the case can give you a little help)
