Abstract: In order to solve information security problems caused by the crack of triple encryption algorithm of Mifare 1(M1) card, this paper proposes some security mechanisms and policies. It need not send plaintext between communicating parties but ciphertext. By using fast and secure Advanced Encryption Standard(AES) algorithm and combing fixed key and random key, the security of encrypted data is improved. Experiments on embedded Linux systems show that M1 card system is stable, secure and efficient.
