  2. NFCwork items • NFC-SEC: NFC Data Link security to complement higher layer security (started) • NFC-FEC: RF Front-end configuration (started) Possible future work items: • NFC-WI-FAST: 2nd generation wired interface • NFC-FAST: Higher data rates • NFC-PCT: Application extensions in NFCIP-1 • Power control as an example application extension • MemorySpot: 2,4GHz High Rate Near Field Communications (planned) Rue du Rhône 114 - CH-1204 Geneva - T: +41 22 849 6000 - F: +41 22 849 6001 - www.ecma-international.org 2

  3. NFC-SEC Overview Motivation: wireless network easy setup, peer-2-peer, mobile phone payment, ticketing and wired equivalent privacy use cases Application independent security layer. For protecting NFC peer-to-peer communications New feature for NFCIP-1 Good balance between state-of-the-art security and performance Rue du Rhône 114 - CH-1204 Geneva - T: +41 22 849 6000 - F: +41 22 849 6001 - www.ecma-international.org 3

  4. NFC-SEC details Protection against: • Eavesdropping • Data modification (on the NFC link) 2 services are available: • Secure Channel • Shared Secret Security protocol: • Key establishment phase • Secure data exchange phase (encryption and MAC) Encapsulated in DEP packets Rue du Rhône 114 - CH-1204 Geneva - T: +41 22 849 6000 - F: +41 22 849 6001 - www.ecma-international.org 4
