In this letter, we propose a privacy-preserving authentication protocol with RSA cryptosystem in an RFID environment. For both overcoming the resource restriction and strengthening security, our protocol uses only modular exponentiation with exponent three at RFID tag side, with the padded random message whose length is greater than one-sixth of the whole message length.
