In CRYPTO13, Gentry et al.proposed a fully homomorphic encryption scheme, called GSW.We find that the scheme has three special properties, which are not sufficiently recognized and applied in current literatures.Property 1: Noise grows asymmetrically in multiplication.

ZhengYu Wu等[1],于2012年提出,X86虚拟化平台上以内存总线为媒介的侧信道.这种侧信道的传输速率首次达到了TCSEC(Trusted Computer System Evaluation Criteria)给定的阈值.另外,其可靠,易控制的特点使得这种侧信道攻击更加危险.
篡改是软件保护过程中的一大难题.近年来,进程级虚拟机(Process-Level Virtual Machine,PVM)保护方案的研究成为软件防篡改方案的一个热点.多数已有的PVM工具都将待保护程序关键代码段的信息进行变换后转储至新的代码空间.然而,攻击者可以利用攻击工具或技术定位分析新代码段的位置以及包含的内容,通过静态和动态分析得到新代码段的组织结构或执行原理.本文分析整理PVM保护机制,并
