简介：当前基于身份(标志)cryptosystem缺乏两大政党的认证和用户的私人钥匙的机制分发。一些基于标志的signcryption计划和基于标志的证实的关键协议协议被介绍了，但是他们不能完全解决这个问题。一个新奇基于标志的认证计划基于基于标志的加密(IBE)和指纹哈希方法被建议在IBE计划解决困难，它包括证实发送者的消息接收装置，证实用户并且把私人钥匙传给他们的信任权威(TA)。而且，计划从终端扩大指纹认证的应用程序到网络并且免于指纹数据制造。指纹认证方法由二个因素组成。这个方法联合一个标志例如，给USB钥匙调音，与用户由混合有指纹特征的一个假散乱数字的指纹回锅肉丁。安全和试验性的效率满足实际应用的要求。
