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 enough plaintext -ciphertext pairs are provided, this approximat ion can be used...

RSA(Rivest–Shamir–Adleman algorithm)算法是一种基于大数分解的困难性的非对称加密算法,它需要选择两个大素数作为私钥的一部分,然后计算出它们的乘积作为公钥的一部分(寻求两个大素数比较简单,而将它们的乘积进行因式分解却极其困难)。RSA 算法原理的详细介绍,可以参考这篇文章:你真的了解 RSA 加密算法吗? - 小傅...
本文列举了 数据加密算法(Data Encryption Algorithm,DEA) 密码学中的高级加密标准(Advanced EncryptionStandard,AES)RSA公钥加密算法 的加密解密 .NET实现以及 安全哈希算法(Secure Hash Algorithm)和MD5的实现。 实现如下 usingSystem; usingSystem.Security.Cryptography; ...
Cryptography is a science of keeping data transfer secure, so that eavesdroppers (or attackers) cannot decipher the transmitted message. The results indicate that the proposed approach is efficient in finding missing key bits of the data encryption standard Algorithm. Keywords — Encryption; Key; ...
