网络密文硬盘中的高效认证方案

A secure and efficient authentication scheme based on network cryptographic hard disk

网络密文硬盘可以解决本地存储空间不足、存储安全性低等问题,为用户提供资料的安全备份。本文分析了网络密文硬盘的实现原理,分析并指出文献中基于AES的网络文件传输协议和认证协议在应用中产生的瓶颈,设计了一种采用随机数的用户认证方式应用于网络密文硬盘系统中,提高了认证的效率和可靠性。理论分析和实际测试都表明该方案可以大大提高服务器端的签名效率,从而提高通信传输效率,解决服务器端的通信瓶颈问题。

Network cryptographic hard disk can solve the problems such as the lack of local storage, local storage with low security and so on. It can provide users secure storage space and secure documents backup. We analyzed the way to realize the network cryptographic hard disk, and analyzed the transmission protocol based on AES in, pointed out the shortcomings of authentication protocol and the bottleneck that authentication protocol brought in this system, then designed a new protocol using random numbers for communication, improved the security and efficiency of authentication. With theoretical analysis and test, the method improved the efficiency of signature on server and the efficiency of transmission greatly, and solved the bottleneck of communication on server as well.
