Systems and methods for securing near field communications

摘要

Systems and methods to secure near field communications (NFC) are disclosed. An NFC polling device may detect a change in voltage when attempting to communicate with another NFC device and based at least in part on the magnitude of the change in voltage if there is an attempted hacking and/or snooping event. The NFC polling device may further identify the number of modulation voltage levels detected and determine if there is an attempted hacking event based on the number of modulation voltage levels detected.

主权项

1. A method, comprising:
emitting, by a polling device comprising one or more processors, an electromagnetic field; identifying, by the polling device, a voltage at a first time by sensing the electromagnetic field at the first time by a sensing element; identifying, by the polling device, a voltage at a second time by sensing the electromagnetic field at the second time by the sensing element; and determining, by the polling device and based at least in part on the voltage at the first time and the second time, that there is no attempted hacking event.
