Abstract
Following the White Paper HCE that Google released in August 2014, it was expected that NFC mobile phone payment would cause a wave of security discussion. After all, Android HCE will allow anyone to develop his own payment service on the Android platform to get rid of restriction from telecommunications, financial industries, or third party trust centers. On this security mechanism observation period, we propose a lightweight authentication protocol on NFC mobile sensors payment. Through introducing this security agreement, it not only allows individuals to have privacy protected, but also can prevent malicious attackers from the track, which will make legitimate Tags verified, while effectively preventing an illegal Tag from being forged as an authenticated Tag. Therefore, constructing full security mechanisms will benefit to the development of mobile NFC payment.
