摘要： 针对Windows Mobile系统对钩子函数支持不足，导致不能方便地保护注册表的情况，提出为系统API建立钩子函数的方法。根据Windows Mobile系统的API调用过程，为操作注册表的一系列API建立相应的钩子函数，从而通过钩子函数有效地拦截API。实验结果显示，该方法能有限拦截操作注册表的API，达到有效保护注册表和提高系统的安全性的目的。

Abstract: According to the situation of Windows Mobile system which does not support normal hook functions and can not be used to protect the registry of system, this paper proposes to build hook functions for the system APIs. Based on the API call process in Windows Mobile system, it builds hook function for the API which regarding to the operation of registry, and intercepts this API. Experimental results shows that it can protect the registry effectively by intercepting the relevant API and improve the system’s security.

Key words: Windows Mobile system, registry, hook function
