Encryption has become a part and parcel of our lives and we have accepted the fact that data is going to encrypted and decrypted at various stages. However, there is not a single encryption algorithm followed everywhere. There are a number of algorithms existing, and I feel there is a need to understand how they work. So this text explains a number of popular encryption algorithms and makes you look at them as mathematical formulas.

HDB3码编码器
本文以FPGA为硬件平台，基于EDA工具QUARTUSⅡ为软件平台上对HDB3编/译码进行实现。由于在EDA的软件平台QUARTUSⅡ上不能处理双极性的信号，因此对HDB3码的编/译码的实现分为：软件部分和硬件部分。软件部分是基于QUARTUSⅡ的平台上对输入的码元进行编码和译码，通过系统仿真，验证了HDB3码的编译码的正确性；硬件部分采用CD74HC4052双四选一的数模选择器实现单极性到双极性的转换；采用AD790和SE5539实现双极性到单极性的转换。最后，通过仿真，验证了方案的正确性。
