LLCPS: A new secure model for Internet of Things services based on the NFC P2P model

This paper presents a new secure model for NFC (Near Field Communication) services based on the P2P (Peer to Peer) mode. NFC is a proximity communication technology more and more supported by smartphones or consumer devices that seems a promising technology for the Internet of Things (IoT). It is used in applications such as payment, access control, transport and more generally for the exchange of small pieces of information. NFC P2P sessions are managed by the Logical Link Control Protocol (LLCP). We introduce LLCPS, a TLS security layer working over LLCP. This framework enforces data privacy and integrity; it also provides identity to smart objects, bound to certificates providing strong mutual authentications. Two experimental platforms are described built with NFC devices and smartphones.
