DSA 全称为Digital Encryption Standard,是基于整数有限域离散对数难题的,其安全性与RSA相比差不多。DSA的一个重要特点是两个素数公开,这样,当使用别人的p和q时,即使不知道私钥,你也能确认它们是否是随机产生的,还是作了手脚。RSA算法却做不到。 ECC 全称为Elliptic Curves Cryptography,也叫椭圆加密算法,是一种公钥...

2. DSA DSA全称Digital Signature Algorithm,DSA只是一种算法,和RSA不同之处在于它不能用作加密和解密,也不能进行密钥交换,只用于签名,所以它比RSA要快很多,其安全性与RSA相比差不多。DSA的一个重要特点是两个素数公开,这样,当使用别人的p和q时,即使不知道私钥,你也能确认它们是否是随机产生的,还是作了手脚。...
Digital signature is a kind of widely used digital signature scheme based on RSA public key cryptography. Its security largely depends on intractability of a large-and-whole prime number, similar to a single function of the inverse. Getting such a large-and-whole prime number is not an easy ...
186 in 1993. DSA is a variant of the ElGamal Signature Scheme. 1. 2. 3. 4. 5. 6. 7. DSA是ElGamal签名方案的变种,被美国NIST作为DSS(DigitalSignature Standard)。其安全性依赖于离散对数难题的,这里不作扩展,仅从应用入手,有兴趣可以自学Jonathan Katz,Yehuda Lindell编著的现代密码学一书。
ElGamal encryption is used in the free GNU Privacy Guard software, recent versions of PGP, and other cryptosystems. The Digital Signature Algorithm is a variant of the ElGamal signature scheme, which should not be confused with ElGamal encryption. ...
Now, I have the RSA public key corresponding to that private key which was used to encrypt the hash. I want to decrypt the digital signature using the RSA public key so that it gives me the SHA-256 hash of the body of message that was sent by the server. I can later compare th...

This paper introduces a scheme for authentication and digital signature. This scheme is based on block cipher hashing and RSA crypto-systems. At the sending end the message is encrypted, hashed, and signed and at the receiving end it is decrypted and verified. The implementation at both sides ...
