1 公钥密码的起源 公钥密码算法(也称双钥密码算法)是非对称的密码算法,即其密钥分为公钥和私钥,因此被称为公钥密码体制,其公钥可以公开。公钥密码技术的出现,给密码的发展开辟了新的方向。公钥密码技术虽然已经历了20多年的研究,但仍具有强劲的发展势头,在认证系统和密钥交换等安全技术领域起着关键的作用。 在传统密码体制(也称对称密钥密码体制)中,
1 Origin of Public Key The public key algorithm (also known as double key algorithm) is an asymmetric cryptographic algorithm, that is, the key is divided into a public key and a private key. Therefore, the public key is known as a public key cryptosystem and its public key can be public . The emergence of public key cryptography has opened up a new direction for the development of cryptography. Although public key cryptography has undergone more than 20 years of research, it still has a strong momentum of development and plays a key role in security technologies such as authentication systems and key exchange. In the traditional cryptosystem (also known as symmetric key cryptosystem)
