Hash
- 雜湊法(Hashing)的搜尋與一般的搜尋法(searching)是不一樣的。在雜湊法中,鍵值(key value)或識別字(identifier)在記憶體的位址是經由函數(function)轉換而得的。此種函數,一般稱之為雜湊函數(Hashing function)或鍵值對應位址轉換(key to address transformation)。對於有限的儲存空間,能夠有效使用且在加入或刪除時也能快的完成,利用雜湊法是最適當不過了。因為雜湊表搜尋在沒有碰撞(collision)及溢位(over

AES
- AES的基本要求是,采用对称分组密码体制。AES的加密数据块长度固定为128 比特,密钥长度则可以是128,192或256比特。AES加密有很多轮的重复和变换。大致步骤如下:1、密钥扩展(KeyExpansion)。2、初始轮(Initial Round)。3、重复轮(Rounds)。每一轮由四个不同的阶段组成,包括一个混淆和三个代换:字节代换(SubBytes)、行移位(ShiftRows)、列混淆(MixColumns)、轮密钥加(AddRoundKey)。4、最终轮(Final Round
