HB+ Authentication

HB+ is a secure authentication protocol that is extremeley simple to implement in hardware. Its low implementation cost could make HB+ useful in preventing "skimming", counterfeiting, or cloning of cheap pervasive devices like RFID tags. HB+ was developed with Ari Juels of RSA Security and was presented at Crypto'05. HB+ builds on a protocol for human-to-computer authentication originally developed by Nick Hopper and Manuel Blum (HB).

Here are presentation slides from Crypto'05 and another page about HB/HB+.
