NFC work items
  • Current work items
  • NFC-SEC NFC Data Link security to complement
    higher layer security (2008-12 GA)
  • NFC-FEC RF Front-end configuration (2008-12 GA)
  • MemorySpot 2,4 GHz High Data Rate (2009-06 GA)
  • Possible future work items
  • NFC-WI-FAST 2nd generation wired interface
  • NFC-FAST Higher data rates
  • Consider a low Hmax profile for Ecma-340 for
    mobile use
  • NFC-PCT Application extensions in NFCIP-1
  • Power control as an example application extension

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

  • 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)
