基于嵌入式Linux的RFID安全性研究

Study of RFID Security Based on Embedded Linux

针对M1卡NXP加密算法被破解所导致的信息安全问题,提出通信双方无须传送明文、只须传送密文的安全机制和策略。选用安全快速的高级加密标准算法,通过固定密钥和随机密钥相结合的方式提高加密数据的安全性,并在嵌入式Linux系统上进行实现,结果证明M1卡系统运行稳定、安全、高效。

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.
