Initial Thinking

• Data-link subnetwork

  • every smart card is a host, the terminal is gateway router
  • need an addressing scheme on this subnetwork
  • IPv6 will require a data-link fragmentation protocol

• IP over ISO 7816-3

  • data field is IP packet
  • 5-byte header describes packet

• ARP

  • include ATR

• Both static and dynamic address cards seem to be useful

  • start with IPv4

• Need a transaction model
