RSA数字签名算法和RSA加密算法相似,不同的是,RSA加密算法是公钥加密,私钥解密,而RSA签名算法是私钥签名,公钥验证签名。DSA(Digital Signature Algorithm)数字签名算法生成签名、验证签名的机制和RSA数字签名算法是一样的。这里不详细展开,这些算法都比较成熟,有丰富的资料可参考,一般网络库也都有实现,有兴趣的朋友自行搜...

The SM2 digital signature algorithm can provide an authentication mechanism for data to solve such problems. Unfortunately, it still suffers from the problem of key exposure. In order to address this concern, this study first introduces a key-insulated scheme, SM2-KI-SIGN, based on the SM2 ...

SM2数字签名算法(SM2 digital signature algorithm,SM2-DSA)是中国版的ECDSA,虽然两者的安全性都依托于椭圆曲线离散对数难题(elliptic curve discrete logarithm problem,ECDLP),但SM2-DSA的安全性要高于ECDSA[2]。尽管理论上SM2-DSA和ECDSA都是安全的,但如果在算...
This letter evaluates SM2 digital signature algorithm's (SM2-DSA) security against a novel lattice-based fault attack targeting nonce and proposes countermeasures to enhance implementation security.

DSA(Digital Signature Algorithm):数字签名算法,是一种标准的 DSS(数字签名标准),严格来说不算加密算法。 ECC(Elliptic Curves Cryptography):椭圆曲线密码编码学。ECC和RSA相比,具有多方面的绝对优势,主要有:抗攻击性强。相同的密钥长度,其抗攻击性要强很多倍。计算量小,处理速度快。ECC总的速度比RSA、DSA要快得...
实现数字签名有很多方法,目前数字签名采用较多的是公钥加密技术,如基于RSA Date Security 公司的PKCS( Public Key Cryptography Standards )、Digital Signature Algorithm、x.509、PGP(Pretty Good Privacy). 1994年美国标准与技术协会公布了数字签名标准(DSS)而使公钥加密技术广泛应用。&127;公钥加密系统采用的是非对称...

Abstract :The SM2digital signature algorithm is the Chinese version of the Elliptic Curve Digital Signature Algorithm (ECDSA).Although the design of the algorithm is mathemati-cally safe,it is vulnerable to physical attacks when the algorithm is implemented.There-fore,it is of great significance to ...
