简介：与传统的秘密成员相比--graphy，视觉密码学(VC)解密指人的视觉，而非密码学知识或复杂计算的特征的秘密图象。而且，看到秘密钥匙的自由，象为视觉密码学的解密一样的加密的整个过程遇见一堂快处理功课。至于安全担心，它能保证没有人能从单个盖子图象关于一幅秘密图象的内容存取任何线索。由于这个区域上的研究，因此，light-weighted密码学的目标被到达。现在，视觉密码学从无意义的阴影被开发了到有意义的。看到高度发达的技术，一些先进VC技术分别地在这调查被介绍。

简介：分享的一个公开可证实的秘密(PVSS)计划是有任何人能验证份额的特殊性质的一个可证实的秘密分享计划他们是否由一个交易者是正确地分布式的。PVSS在象电子投票，有可撤回的匿名的支付系统，和关键附带条件契约那样的许多应用程序起一个重要作用。直到现在，所有PVSS计划基于传统的公共密钥的系统。最近，基于对的密码学从密码的研究人员收到了许多注意。许多基于对的计划和协议被建议了。然而，用双线性的配对的PVSS计划都没被建议。这份报纸论述第一个基于对的PVSS计划。在随机的神谕模型并且在双线性的Diffie-Hellman假设下面，作者证明建议计划是一个安全PVSS计划。

简介：分享计划的一个量秘密被使用quantumregisters建议。在建议计划，秘密消息状态被编码进多国参加的entangledstates。几个相同多粒子纠纷状态被产生，theentanglement状态的每个粒子被填充当secretmessage的份额的不同的量寄存器。二个模式，即检测模式和消息模式，被采用以便theeavesdropping能容易被检测，秘密消息可以被恢复。建议计划对偷听者偷听并且欺骗ofparticipants是安全的安全analysisshows。
