摘要
利用视觉密码来构造一种新的访问控制方案,可以有效弥补传统访问控制方案的不足,从而使方案更可靠,更高效。视觉密码的安全性仅依赖于伪随机数的性能,不涉及到复杂的密码学算法,因此速度较快。方案中提出的访问控制协议分为注册和登录验证两步,易于实现。最后,分析了该方案对常见攻击的抵抗。
Based on the analysis of defect of traditional access control scheme,a new efficient and credible scheme which is structured by us ing visual cryptography is presented.The security of visual cryptography depends solely on the performance of pseudo random numbers,not involving complicated cryptographic algorithm,so it is very fast.The access control protocol which is presented in the scheme includes two steps,which are register and logging in validity,so it is easy to realize.Finally,the resist on common attack is analysized.
