In this paper, linear cryptanalysis is a known-plaintext attack that uses a linear relat ion between input-bits, output- bits, and key-bits of an encryption algorithm that holds with a certain probability. If e
Iterated Block Cipher- A block cipher that "iterates a fixed number of times of another block cipher, called round function, with a different key, called round key, for each iteration". Feistel Cipher- An iterate block cipher that uses the following algorithm: Input: T: 2t bits of clear ...
DES全称为Data Encryption Standard,即数据加密标准,是一种使用密钥加密的块算法,1977年被美国联邦政府的国家标准局确定为联邦资料处理标准(FIPS),并授权在非密级政府通信中使用,随后该算法在国际上广泛流传开来。需要注意的是,在某些文献中,作为算法的DES称为数据加密算法(Data Encryption Algorithm,DEA),已与作为标准...
In cryptography, theElGamalencryption system is anasymmetric key encryption algorithm(非对称密钥加密算法)for public-key cryptography which is based on the Diffie–Hellman key exchange. It was described by Taher Elgamal in 1985. ElGamal encryption is used in the free GNU Privacy Guard software, recen...

译⾃J. Orlin Grabbe的名作《DES Algorithm Illustrated》,国外许多⼤学将该⽂章作为补充材料,可作为理解DES算法的最佳⼊门⼿ 册。反观许多教材介绍DES时直接照搬⼀张流程图,图中IP等缩写符号不加解释,让⼈误解;许多博客则直接给出蹩脚的源码,对内部流程 缺乏解读。事实上,DES在算法上并不复杂,只是流程...

AES Algorithm AES, Advanced Encryption Standard, also known as Rijndael encryption in cryptography, is a block encryption standard adopted by the US federal government. AES block length is fixed at 128 bits, the key length can be 128, 192 or 256 bits. It including AES-ECB,AES-CBC,AES-CTR...
ECC(Elliptical Curve Cryptography)椭圆曲线加密算法是以椭圆曲线理论为基础实现的,通过椭圆曲线方程式的性质产生密钥,而不是采用传统的方法利用大质数的积来产生。在创建密钥时更快、更小。 示例 import java.security.AlgorithmParameterGenerator; import java.security.AlgorithmParameters; import java.security.Key; imp...
