Dan Boneh密码学笔记3

搞清楚DES、3DES、AES算法原理及其安全性。

区分PRG、PRF、PRP三个概念。

1.what is a block cipher?

2.The data encryption standard(DES)

3.Exhaustive Search Attacks

4.more attacks on block ciphers

5.The AES block cipher

6.Block ciphers from PRGs

补充: 异或运算的简单性质

1. a ⊕ a = 0

2. a ⊕ b = b ⊕ a

3. a ⊕b ⊕ c = a ⊕ (b ⊕ c) = (a ⊕ b) ⊕ c;

4. d = a ⊕ b ⊕ c 可以推出 a = d ⊕ b ⊕ c.

5. a ⊕ b⊕ a = b.
