實現IDEA加密算法與解密算法 IDEA(International Data Encryption Algorithm)是瑞士的James Massey,Xuejia Lai等人提出的加密算法,在密碼學中屬于數據塊加密算法(Block Cipher)類。IDEA使用長度為128bit的密鑰,數據塊大小為64bit。從理論上講,IDEA屬于“強”加密算法,至今還沒有出現對該算法的有效攻擊算法。

數據加密算法(Data Encryption Algorithm,DEA)的數據加密標準(Data Encryption Standard,DES)是規范的描述,它出自 IBM 的研究工作,并在 1997 年被美國政府正式采納。它很可能是使用最廣泛的秘鑰系統,特別是在保護金融數據的安全中,最初開發的 DES 是嵌入硬 件中的。通常,自動取款機(Automated Teller Machine,ATM)都使用 DES。文件是DES代碼的VHDL描述
