A method for mutual authentication in an RFID system comprising an RFID reader and an RFID tag, the method comprising requesting an identification from the tag, receiving the identification, using the received identification to select a password associated with the identification, generating a password key based on the selected password, encrypting the selected password using the password key, and transmitting the encrypted password to the tag.

RFID authentication architecture and methods for RFID authentication

A radio frequency identification (RFID) integrated circuit includes a transceiver and a processing device. The transceiver may to transmit a first continuous wave radio frequency (RF) signal to a bridge in a no-wire format via an antenna, where the transceiver is to start transmitting the modulated or continuous wave RF signal at a first amplitude value and increase an amplitude of the modulated or continuous wave RF signal to a second amplitude value at which an acknowledge (ACK) pulse is detected. The transceiver may receive a reflected wave RF signal in the no-wire format. The processing device may detect the ACK pulse in the reflected wave RF signal. The processing device may transmit a second modulated or continuous wave RF signal to the transceiver in the no-wire format.
