    摘要: Provided is a method for authentication between a radio frequency identification (RFID) tag and an interrogator configured to communicate with the RFID tag. An authentication method performed by the interrogator may include: transmitting, to an RFID tag, a challenge command comprising random interrogator information for initializing an encryption engine and challenge interrogator information for authenticating the RFID tag; receiving, from the RFID tag, random tag information, encrypted challenge tag information, and encrypted tag authentication data; initializing the encryption engine based on the random to interrogator information and the random tag information; decrypting the encrypted challenge tag information and the encrypted tag authentication data; and authenticating the RFID tag based on the decrypted challenge tag information, the decrypted tag authentication data, and the challenge interrogator information.
