[Cryptography] Near field and crypto

[Tom Mitchell]

Near field devices are in anything and everywhere.

Modern phones can read or present an NFC ID on demand.
Apple uses NFC for payment on some models of phone.

They can contain between 96 and 4,096 bytes of information.
which is sufficient to pass an interesting sized key, a URI,
or to unlock a keyring with locked PGP private key.

NFC and RFID devices are easy to hide on benches in public places.
A set of passive RFID devices uniquely identifies most individuals.

Could passive RFID/NFC in a shoe, jacket or purse become the next
big data slurp target.

Could these devices be the critical long set of bits that when combined
with modest known salt be a useful part of key management systems?
