Implementation and Analysis of a Practical NFC Relay Attack Example

NFC(near field communication) technology is a kind of technology to provide close RFID communication channel on mobile devices. Peer-to-Peer applications based on mobile equipment rely on NFC. The NFC system is facing a security problem that it is susceptible to a relay attack. This paper discusses the realization of relay attack on a legitimate peer-to-peer NFC. The attackers use mobile phones with the NFC function of the Android platform, and install the programs on the mobile phones, can finish the attack. While these attack programs only need to call the public NFC protocol API, without illegal intrusion to device memory. On this foundation, how the existing NFC protocol to avoid the above attack is discussed.
