RSA Public-Key Encryption AlgorithmThe RSA is one of the popular public-key encryption algorithms. Rivest et al. published a method for obtaining digital signatures and public-key cryptosystems in 1978 [1]. In order to use the method,...Springer USdoi:10.1007/978-0-387-78414-4_198

RSA Public-Key Encryption and Signature LabRSA(RIVEST-Shamir-Adleman)是第一个公钥密码系统之一,广泛用于安全通信。 RSA算法将生成两个大的随机素数,然后使用它们生成公钥和私钥对,该对可用于进行加密,解密,数字签名生成和数字签名验证。 RSA算法建立在数字理论上,并且可以通过库的支持很容易地实现。

这种加密方式被成为对称加密算法(symmetric encryption algorithm) 1976年,两位美国计算机学家 迪菲(W.Diffie)、赫尔曼( M.Hellman ) 提出了一种崭新构思,可以在不直接传递密钥的情况下,完成密钥交换。这被称为“迪菲赫尔曼密钥交换”算法。开创了密码学研究的新方向 RSA数学原理 上世纪70年代产生的一种加密算法。其...

加密算法(Encryption)：若E(x)为加密算法，加密过程可以理解为C = E(M)根据原文和加密算法得到密文。
RSA is an algorithm used for Cryptography. It was patented until 2000 in the USA (not the whole world) where now it can be used freely. RSA has a lot of usage examples but it is mainly used for encryption of small pieces of data like key and Digital signatures. RSA is based integer...
非对称加密算法主要有: (1)RSA:由 RSA 公司发明,是一个支持变长密钥的公共密钥算法,需要加密的文件块的长度也是可变的; (2)DSA(Digital Signature Algorithm):数字签名算法,是一种标准的 DSS(数字签名标准); (3)ECC(Elliptic Curves Cryptography):椭圆曲线密码编码学。
