IDEA算法实例【包含C和执行文件】
官方C/C++开发工程师QQ群(1090119),验证请输入您的ID。文件包括IDEA的加密和解密算法,有c文件和履行文件。IDEA是InternationalDataEncryptionAlgorithm的缩写,是1990年由瑞士联邦技术学院来学嘉X.J.Lai和Massey提出的建议规范算法称作PES(ProposedEncryptionStandard)。Lai和Massey在1992年进行了改进强化了抗差分分析的才能改称为IDEA它也是对64bit大小的数据块加密的分组加密算法密钥长度为128位它基于“相异代数群上的混合运算”设计思维算法用硬件和软件实现都很简单且比DES在实现上快的多。IDEA自面世以来,现已阅历了很多的详细审查,对密码分析具有很强的抵抗才能,在多种商业产品中被使用。IDEA\IDEA.cpp

(Official C/C development engineer QQ group (1090119), please enter your ID for verification. The files include IDEA's encryption and decryption algorithms, c files and fulfillment files. IDEA is the abbreviation of International Data Encryption Algorithm, which is a proposed standard algorithm called PES (Proposed Encryption Standard) proposed by X.J. Lai and Massey of the Swiss Federal Institute of Technology in 1990. It was improved by Lai and Massey in 1992 to strengthen the ability to resist differential analysis and was renamed IDEA. It is also a block encryption algorithm for encrypting data blocks of 64bit size. The key length is 128 bits. It is based on "mixed operations on dissimilar algebraic groups" Design thinking algorithms are simple to implement in hardware and software and much faster than DES in implementation. IDEA has gone through a lot of scrutiny since its inception, has strong resistance to cryptanalysis, and is used in a variety of commercial products.
