This research study and analyze the various attacks RFID card on Mifare's disadvantage and safety concerns crux of the problem. The key recovery attack method depends on a plaintext-ciphertext pair on the existing relationship, as well as the secret parameters of the pseudo random number for use of the timing inappropriate. The authors proposed a scheme to improve the mechanisms for authentication, no additional secret parameters into the standard, solely by readers and tags communication between the timing of the change of use of the secret parameters. This mechanism can make plaintext-ciphertext pair of the derivation relationship does not exist and be used in the Mifare-like of the RFID products.
