【摘要】 分析了传统远程访问控制方案中的不足,并基于视觉密码构造了一种高效、可靠的远程访问控制方案。方案中仅使用了视觉密码和对称密码算法这两种密码组件,不涉及到非对称密码、消息认证码等,可以提高访问控制的处理速度。方案分为离线注册和远程在线登录验证两个阶段,认证协议简单,易于实现。最后分析了方案的安全性,说明其能有效抵抗常见的攻击方式。更多还原

【Abstract】 The defect of traditional remote access control is analyzed,and an efficient and credible scheme of remote access control is constructed based on visual cryptography.In this scheme,only two kinds of cryptography components are used,which are visual cryptography and symmetric cryptography,neither unsymmetrical nor MAC,so the processing speed of access control can be raised.The scheme includes two stages which are offline register and online login validation,the authentication protocol is simple and easy to realize.Finally,the safety of the scheme is analyzed and the result shows that the scheme can resist common attacks effectively.更多还原
