| The history of researching on smart home system is just only 20 years, but the development speed is amazing. Nowadays the "smart home" is realized in many families, the design of home gateway is one of the most important design of smart home system, the traditional design of home gateway is based on PC, but consider the utility and price, embedded home gateway is the satisfying choice. The main function of embedded home gateway is to realize embedded Internet.As an embedded home gateway, in one hand, it must realize the function of transform between the TCP/IP and home network protocol; in the other hand, when the home devices were remote visited using Internet, it bring forward a lot of convenience, but at the same time, the home device is exposed to the others, it in face of much security threaten. So, when designing an embedded home gateway, the security of it must be considered at first. Since the particularity of the embedded device and the environment of the home network, the security mechanism must be different from the PC.Under the background mentioned before, this paper based on the 32-bit ARM Microprocessor and the environment of RTOS, research and design one embedded home gateway, and do some security mechanism research on this embedded home gateway. Our research job is as blow:1 based on the 32-bit ARM Microprocessor and the environment of RTOS, according to the different standard of home network protocol, bring forward an new design method of embedded home gateway, be compared with the traditional design method, this method is not according to a exclusive home network protocol, but bring forward a general design method, it can make different home network protocol connection to Internet without leak.2 do some systemic analysis of security threaten of the smart home system and embedded home gateway, then bring forward new mechanism to improve the security of smart home system which was connected to Internet by embedded home gateway,... |
