| With the rapid development of electronic information technology,Network applications and network services have go deep into all aspects of people’s life in recent years.Usually,they manage their Visitors by member mechanism.The traditional way to identify their members which base on user name and password exists lots of safety loopholes,such as easy leak of password.Aiming at these shortages,this paper proposes a new way of certification which based on the non-contact IC card certification.This kind of authentication features high safety,easy operation and can reduce the user memory burden,has certain practical application value and market value.Basing on the elderly health service center project of a corporation in Zhenjiang city,this paper designed and implemented the IC card authentication system on Android platform.The main work of this paper follows:(1)The authentication mechanism of RFID system is studied and an improved security authentication protocol based on the Hash-Lock protocol is proposed.Then the Security authentication protocol between the IC card and back-end servers is designed.Also,the communication protocol between Android applications and back-end servers is designed.(2)With the STM32F103CBT6 chip as Micro controller and MF CV520 chip as read/write chip,the hardware and software of Read/write device is designed.The hardware part includes the design of MCU module circuit,the read/write module circuit and antenna circuit.The software part includes MCU initialization program,the operation of the read/write chip function and PC interface function for card.(3)With analyzing the functional requirements of Android client,the client program overall process and all function modules are designed.The communication between Android client and read/write device,communication between Android client and back-end service are realized.(4)The testing of system is done.Finally,the test result shows that the system runs in a good performance. |
