The NIST Statistical Test Suite ( Revised by Larry Bassham, March 2008)， 用于测试序列的随机性. 从NIST上下载的源代码，稍微修改了一下，附带一个已经编译好的32位Exe程序。主要修改如下：1）增加了大量的帮助信息；2）优化了参数交互，全部功能支持命令行参数化，原来的需要手动输入一些命令；3）增加了测试的日志功能和进度显示。

Basics of Side-Channel Analysis

About SecurAble This "SecurAble" GRC freeware was an outgrowth from several "Security Now!" podcasts with Leo Laporte. These MP3 audio files are freely available for download from GRC's web site in both smaller-sized 16 kbps and higher-quality 64 kbps versions, and textual transcripts of the programs are also available: http://www.GRC.com/SecurityNow The following episodes will be of particular interest: # 66 - Windows Vista Security # 67 - Kernel Patch Protection # 71 - SecurAble What is "SecurAble" ? Future PC security will increasingly rely upon specific hardware capabilities offered by modern processors: As Windows makes the painful move from a 32-bit kernel to a new kernel running in 64-bit mode, Microsoft is working to avoid repeating mistakes made during the 32-bit era. Consequently, 64-bit versions of Windows will offer significantly stronger security than was ever available to Windows 32-bit operating systems. Most modern computer vulnerabilities arise from communications buffers that can be overrun with malicious data. This allows remote attackers to inject their own code into vulnerable computers across the Internet. Modern processors incorporate explicit hardware controls to prevent the mistaken execution of remotely supplied data. This "data execution prevention" (DEP), when available and active, enables the most promising improvement in PC security ever seen. To improve the performance of systems running "virtual machines" (VMs), modern processors added hardware support to allow securely encapsulated VMs to run at the same speed as non-VM systems. This benefits security by increasing the robustness of, and removing all performance penalties from, the continuous use of virtual machine technology. Since virtual machines allow "supervision" by their hosting environment, this supervision can be used to dramatically increase the system's overall security. For the reasons described above, these three modern processor characteristics will play an important role in enhancing personal computing security in the future. But it's not readily clear from "outside the box" which features individual systems may contain. So I created this little "SecurAble" utility to allow anyone to quickly and easily determine which of these useful capabilities their system's processor supports. Note: When running SecurAble, be sure to click on each of the three displayed items to receive additional details about the meaning of the display and the security-related implications of each processor feature.

需要管理员权限运行，因为涉及到设备操作。 先选择要拷贝的文件，然后点击开始工作后。程序将自动检测是否有U盘插入，有的话自动复制之前选中的文件到U盘根目录下，复制完毕就自动退出，等待下一个U盘。 特别适用于大学选修课的老师在课室发布课件。听说现在都流行网络了，也不知道这东西还有没有用。

根据提示，使用快捷键Ctrl_Alt+End结合鼠标选择窗口，可以实现对窗口的隐藏显示，启动禁用，最大化和最小化，查看和修改窗口标题。 调整位置大小的好像有点毛病，没去处理，大家别乱用就好。

程序启动时自动启动列表中的其他程序，当程序收到关机消息时，自动强制关闭列表中的程序。主要用来应对某些阻碍程序关机的讨厌程序。

木有界面，自动后台捕捉热键控制屏幕显示和关闭。开关是Ctrl+Alt+Insert，退出是Ctrl+Alt+Home
