The purpose of this work is to serve as an introduction to quantum chaos. We avoid the usual path of dealing with ensembles of random matrices and instead consider clean one-dimensional systems of spi...
SPINS安全协议基于可信基站，为无线传感器网络数据传输提供了一套安全的解决方案。通过分析SPINS协议，指出其中存在的不足，并对其进行了三方面的改进，即引入全局密钥、支持网络扩展和加入密钥更新机制。分析表明，改进的方案具有较好的扩展性，能有效支持路由信息的认证，新的密钥更新机制在一定程度上增加了安全性。
