摘要
USB Key认证方式是目前应用较多的认证方式。它的理论基础是公开密钥密码体制，公开密钥密码体制的基础是单向陷门函数。求两个大素数的乘积是典型的单向陷门函数，它是RSA算法的核心，构建了数字签名的数学基础。
key authentication method is an authentication method applied in numerous fields presently. Its theoretical foundation is public -key cryptology, and the public -key cryptology foundation is trapdoor one -way function. Find the product of two large prime is a typical of trapdoor one - way function, which is the core of RSA algorithm, constructs the mathematical basis of digital - signature.
