NFC Devices: Security and Privacy

The aim of this paper is to show security measures for NFC (Near Field Communication) use cases and devices. We give a brief overview over NFC technology and evaluate the implementation of NFC in devices. Out of this technology review we derive different use cases and applications based on NFC technology. Based on the use cases we show assets and interfaces of an NFC device that could be a possible target of an attacker. In the following we apply different attacks against the operation modes to show how applications and devices could be protected against such attacks. The information collected is consolidated in a set of threats giving guidelines on how to improve security and overcome privacy issues. This allows integrating NFC technology in a secure way for the end consumer.
