单片机仿真软件DEBUGGER8051简介

一个单片机程序编完以后，调试是不可避免的，这里介绍的DebuggerS051就是一个优秀的单片机仿真软件，它采取了图形界面的多窗口形式，方便灵活地控制和显示着单片机的内部状态，比较适合调试实时性要求不高的程序，以及单片机初学者学习之用，当然如果巧妙运用，同样可以调试复杂的程序。

软件安全Shell的实现

本文基于防止软件被破解与逆向的目的,通过对PE文件导入表、导出表、重定位表的处理实现Shell增加区段的功能。通过将Is Debugger Present与Timing Attacks技术的融合实现Shell自身的反调试,同时采用Shell Code的编码方式存储一些敏感信息以及通过"无效操作码"这一后门接口实现Shell自身的反虚拟机功能。最后通过对Notepad的加Shell试验说明Shell具有反调试与反虚拟机功能,证明了对软件加Shell具有防止被破解与逆向的功能。

Windows系统IFEO映像劫持病毒的分析与防治

映像劫持病毒是近几年来对用户系统安全破坏程度最大的病毒之一,它将大量安全软件"绑架",使其无法正常运行,从而大大降低用户系统的安全性。本文重点剖析了Windows系统IFEO映像劫持技术的原理,并提出了合理的防治映像劫持病毒的方法,为增强用户系统安全提供借鉴。

Windows映像劫持的分析与防范

本文首先介绍了windows映像劫持的原理,对映像劫持进行了分析。同时根据笔者的日常工作经验总结除了一套比较完善的映像劫持防护方法,具有较强的针对性和实际意义。

An Exploratory Study of Experimental Tools for Wireless Sensor Networks

The objective of this contribution is to present expositive review content on currently available experimental tools/services/concepts used for most emerging field Wireless Sensor Network that has capability to change many of the Information Communication aspects in the upcoming era. Currently due to high cost of large number of sensor nodes most researches in wireless sensor networks area is performed by using these experimental tools in various universities, institutes, and research centers before implementing real one. Also the statistics gathered from these experimental tools can be realistic and convenient. These experimental tools provide the better option for studying the behavior of WSNs before and after implementing the physical one. In this contribution 63 simulators/simulation frameworks, 14 emulators, 19 data visualization tools, 46 testbeds, 26 debugging tools/services/concepts, 10 code-updation/reprogramming tools and 8 network monitors has been presented that are used worldwide for WSN researches.
