A mobile station, an access point, a gateway apparatus, a base station, and a handshake method thereof for use in a wireless network framework are provided. The wireless network framework comprises a first wireless network comprising the access point, and a second wireless network comprising the gateway apparatus and base station. There is an IP security tunnel between the access point and the gateway apparatus. When the mobile station handovers from the first wireless network to the second wireless network, it transmits a master session key to the gateway apparatus via the access point and the IP security tunnel. Additionally, when the mobile station handovers from the second wireless network to the first wireless network, it transmits a master session key to the access point. As a result, the authentication time, which is needed in handover procedure between the first wireless network and the second wireless network, is reduced effectively.

Apparatus, method, and computer readable medium for generating and utilizing a feature code to monitor a program are provided. The program is run in a secure environment at the beginning. The program calls a function through an application program interface. A return address of the application program interface is used to generate the feature code. When the application runs again at another time, the feature code is utilized to monitor the program. According to the aforementioned arrangement and steps, the application program interface can be monitored dynamically. Consequently, any program can be monitored by this approach, which results in a more secure environment. Further, fewer application program interfaces are required to be monitored, so the required computer resource is less.
