Research On Data Exchange And Security Based On NFC P2P Mode

With the development of modern communication technology, people demand more and more convenient communication.The Near field communication technology was derived from Radio Frequency Identification technology.NFC technology is convenient and has lower power consumption,it is simple to operate.It provides a simple and convenient method for wireless transmission and data exchange and do not need any other operation. It also can communicate with other phones or read information on tags and cards(reader). A NFC device can also be put in card emulation mode, to compatible with other non-contact smart card standard.In this paper, the NFC model of P2 P data exchange system is proposed based on the characteristics of its convenient.The Interaction.between information can be completed rapidly through close contact between NFC phones.We also make a research about the security of NFC.We research the security of data transmission in the process,Points out the security threats which exist when data is transmitted.So the design of the AES and ECC mixed encryption algorithm was designed to ensure the security of the data.The second security threats was from the missing phone.when the smart phone was lost,everyone can make use of the NFC application and does not need any authentication operation.It is very dangerous for the master of the phone.So this paper proposes an authentication framework to protect our privacy and property without doing great damage to the Simplicity of NFC.which make the NFC not only has simple operation but also more secure.
