Based the traditional Attribute-Based Encryption (ABE) access control systems, this paper first proposes a new access architecture for MCC, which introduces a middle layer sitting between mobile devices and their cloud infrastructure.This middle hyer is composed of cloudlets and thus it is called access cloudlet layer.Cloudlets are deployed next to IEEE 802.11access points (APs) and serve as a localized service point at a mobile devices close proximity to improve the performance of mobile cloud services.On top of this new architecture, an ABE access control scheme is proposed to offload the main amount of computations to the cloudlet as the function of cloud, in which the access control decision making takes into consideration energy consumption of access task execution and network status while satisfiying certain response time constraints.Then the analysis results have shown the effectiveness and efficiency of the proposed system architecture in terms of security and energy consunption.

本文提出一种基于压缩感知和颜色向量角的图像哈希算法.该算法先对输入图像预处理,在此基础上计算其颜色向量角矩阵,然后对矩阵进行非重叠分块,再将每一个分块进行压缩感知测量,最后用测量向量的均值构成哈希值.实验结果表明本文算法对常见数字操作稳健并有较好的唯一性.接收机操作特性曲线对比发现,本文算法的性能优于三种代表性的图像哈希算法.
视频序列拷贝是一种针对监控视频的典型攻击手段,基于内容的取证方法难以区分真实的静态场景和视频序列拷贝.但是自然噪声等因素造成的真实视频序列和拷贝序列之间存在微小的差别会在H.264视频编码过程中得以保留并体现在码流参数中.本文分析了视频序列拷贝的码流参数特征,构造了基于码率的视频序列拷贝检测指标,提出了一种基于码流参数特征的视频序列拷贝检测算法.在大于20帧的视频序列复制情况下,可以实现90％以上

图像隐密分析的目的是,通过分析网络日常图像的微观统计特征,检测图像数据中可能潜藏的秘密信息.采用隐密特征提取结合分类器的隐密分析技术能较好的对隐密图像进行判决.但大多数分类系统的分类精度严重依赖于有标记训练样本的数量.因此,在有限数量的标记样本下,如何充分利用大量无标记样本来提高隐密判决精度已成为隐密分析领域亟待解决的问题.本文结合集成映射的方法,利用有限的有标签数据,充分挖掘大量的无标签样本信息

针对传统湿纸码计算复杂度较高的问题,提出了一种基于约简汉明校验阵的湿纸码快速构造方法.首先分析了汉明校验阵列消减对信息隐藏性能的影响,提出了载体改变不超过2比特的约简汉明校验阵构造方法;在此基础上,依据载体的干湿特性,通过对约简汉明校验阵进行随机列扩展,构造湿纸码的编码矩阵.理论分析和实验结果表明,算法在保证较高的隐写效率的同时有效地降低了计算复杂度.
