| With the popularity of smart phone and the rapid development of Internet of Things(IOT) technology, the phone is undoubtedly become one of the basic platform of the IOT era, the security issues of mobile terminals become the focus of our attention at the same time. This paper uses the application system of the IOT of phone as a platform, work on identify authentication issues at the same time. The research results are as follows:1. Analyze the developments and prospects of IOT as well as the current identity authentication technology.2. Design the IOT application system of phone which is based on3G, Internet of Things applications based on3G. Toenhancesystem security, we design a two-way authentication method between the mobile phone client and server. This method combines the S/Key technology and laboratory patented technology:a method which is a combination of dynamic password and multi-biometric identification.3. Use customer ID generated from phone series number and phone number to realize the binding between the phone client and the user. Select SHA-1as the hash algorithm to generate one-time dynamic password. Use the AES encryption method to encrypt the authentication information, thus to guarantee the transmission security of authentication information.4. Use Samsung S3C2440ARM9as the processor, Huawei EM660as the3G module, use camera in conjunction with a variety of sensors to achieve the hardware part of the system. Use JAVA as the development language, realized the function that the server receiving and processing information, and user management. Use J2ME as the development platform, to develop application program for client.5. Set up the experimental platform, test the function and performance of each module of the system, and the results show that the system function reach the design goals, and the performance can satisfy application needs. Finally, point out the inadequacies of this system and possible improvements. |
