Neste artigo, propomos uma comunicação de campo próximo (NFC) segura para smartphones, combinando comunicação acústica e vibracional. Em nosso sistema híbrido, um transmissor transmite uma mensagem criptografada e uma chave de criptografia de um alto-falante e motor de vibração, respectivamente. Enquanto o som emitido pelo alto-falante se propaga pelo ar, a vibração emitida pelo motor vibratório se propaga pelo corpo dos smartphones. Conseqüentemente, apenas os receptores que tocam o transmissor podem receber a mensagem criptografada e a chave, resultando em uma comunicação segura. Projetamos um software modulador e demodulador adequado para a comunicação vibracional usando código de retorno a zero (RZ). Em seguida, estabelecemos um sistema de comunicação híbrido combinando modems de comunicação acústica e vibracional, e avaliamos seu desempenho em experimentos. Os resultados indicam que nosso sistema híbrido alcançou um NFC seguro (entre dispositivos com contato físico) e rápido (800kbps) para smartphones.

Abstract: In this paper, we propose a secure near-field communication (NFC) for smartphones by combining acoustic and vibrational communication. In our hybrid system, a transmitter transmits an encrypted message and encryption key from a loudspeaker and vibration motor, respectively. While the sound emitted from the loudspeaker propagates through the air, the vibration emitted by the vibration motor propagates through the body of smartphones. Hence, only receivers touching the transmitter can receive both the encrypted message and the key, resulting in secure communication. We designed a software modulator and demodulator suitable for the vibrational communication by using return-to-zero (RZ) code. Then we established a hybrid communication system by combining acoustic and vibrational communication modems, and evaluated its performance in experiments. The results indicate that our hybrid system achieved a secure (among physically contacted devices) and fast (800kbps) NFC for smartphones.
