Description: Thunk和DEP
什么是Thunk
Thunk技术就是将一段机器码对应的字节保存在一个连续内存结构里,然后把其指针强制转换成函数,即用作函数来执行。
什么是DEP
数据执行保护 (DEP) 是一套软硬件技术,能够在内存上执行额外检查以帮助防止在系统上运行恶意代码。在 Microsoft Windows XP Service Pack 2、 Microsoft Windows Server 2003 Service Pack 1 、Microsoft Windows XP Tablet PC Edition 2005 和 Microsoft Windows Vista 中,由硬件和软件一起强制实施 DEP。
DEP 的主要优点是可以帮助防止数据页执行代码。通常情况下,不从默认堆和堆栈执行代码。硬件实施 DEP 检测从这些位置运行的代码,并在发现执行情况时引发异常。软件实施 DEP 可帮助阻止恶意代码利用 Windows 中的异常处理机制进行破坏。
硬件实施 DEP 是某些 DEP 兼容处理器的功能,可以防止在已标记为数据存储区的内存区域中执行代码。 此功能也称为非执行和执行保护。 Windows XP SP2 还包括软件实施 DEP,其目的在于减少利用 Windows 中的例外处理机制的情况。

The Universal Serial Bus USB is specified to be an industry standard
extension to the PC architecture. USB is a serial cable bus that supports data
exchange between a host computer and a wide range of simultaneously
accessible peripherals.
First, the thesis describes the architecture and features of USB, including
the bus attributes, the protocol definition, types of transactions, power
management, and so on. It tries to give developers and users a snapshot of
USB.
After that, the thesis will talk about how to develop the USB system,
including: device hardware, device software and host software.
Then the thesis describes some development and technique details of
several USB projects: USB tablet, USB univeral development tool, USB
security key and USB ISP (In System Program) device. I will give you the
details of the hardware and software design of device, including how to write
USB device protocol stack, and talk about the kernel drivers and user program
in Win
