By offering indisputable advantages over traditional grid including remote readings and load balancing,smart grid is regarded as the modernization of the electricity delivery system.In digital communities,smart grid proposals may threaten user privacy due to potentially disclosing fine-grained consumption data to utility providers.In this paper,we propose a robust and privacy-preserving aggregation scheme for smart grid communications.The construction of member list allows the fault-tolerance of our scheme against accidental errors.By integrating privacy homomorphism encryption and aggregation signature scheme,data authentication and integrity protection are performed and proved without disclosing any fine-grained data records.Security analysis and performance evaluation demonstrate that the proposed scheme can resist various security threats and preserve identity privacy,and has significantly less communication overhead and computation cost than other existing approaches.

可信计算平台技术可以用来增强已有计算环境的安全性.一个可视化的TCG辅助学习系统,可以帮助对可信计算平台技术的理解和学习.本文设计开发了一套windows环境下可视化的TCG辅助学习系统。用户通过该系统可以执行内嵌的TCG应用程序，这些内嵌的TCG应用程序分别执行不同的TPM命令。系统对TCG应用程序执行过程中的重要信息进行收集，并按照模块调用、TCG内部数据、TCG密钥信息和TCG授权协议、TC
密码函数在序列密码和分组密码的设计实现中起着举足轻重的作用。密码函数的构造、表示、计数及其密码学性质的分析是研究密码函数的研究热点与前沿。在序列密码中主要使用的是布尔函数，序列密码的安全性取决于密钥序列的安全性，因此产生密钥序列的布尔函数的密码学性质对一个序列密码体制的安全性起着决定性作用。布尔函数的密码学性质主要有:平衡性、代数次数、非线性度、扩散性和相关免疫性、代数免疫性、正规性等。在构造一个

目前，虚拟化技术(virtualization)在企业中得到了广泛的应用，并具有巨大的市场前景。然而，任何一种平台大规模上线使用后都会成为广大网络黑客攻击的对象，虚拟机也不例外。在虚拟化面临的安全问题中，其中之一是以主机为基础的安全策略难以部署。目前基于虚拟机的安全软件都是基于物理机开发的，其防护方式无一例外都是借助传统方式，而且如果在每一台虚拟机上都安装安全软件，对物理服务器的存储空间、内存资源
