In the basic formula for the RSA cryptosystem [ 16 ] (see also RSA Problem , RSA public-key encryption ), a digital signature s is computed on a message m according to the equation (see modular arithmetic ) (1) $$ s = m^d \\\bmod n, $$ where (n, d) is the signer's RSA...
数字签名 (digital signature) 可以用公钥密码系统的这种形式实现。(还有其他方法可以构建数字签名,但我们在这里不进行展开。)假设现在 Alice 希望向 Bob 发送一个带数字签名的回答 M' 。图 31.6 显示了带数字签名的场景的运行过程。 Alice 使用她的私钥 S_A 和等式 \sigma=S_A(M') 计算消息 M' 的数字签名...

This document defines additional options supporting SSH public keys applying the Elliptic Curve Digital Signature Algorithm (ECDSA) and the implementation of fingerprints computed using the SHA-256 message digest algorithm in SSHFP Resource Records. [STANDARDS-TRACK]...
If one finds solution of this single hard problem then these digital signature algorithms will no longer be secured and due to large computational power, this may be possible in future. The RSA digital signature algorithm (RSADSA) is an asymmetric cryptographic technique, whose security is related...
Digital Signature Standard (DSS) and adopted as FIPS 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Jonatha...
