The existing encryption methods, such as DES, AES, RSA, ECC used for RFID, have heavy encryption burden. To remove the problem, therefore, this paper uses the fastest encryption method RC4 to encrypt RFID tag information. However, it is admitted that the RC4 is a kind of security encryption method which is not good enough to meet the RFID security needs. In this paper, this paper brings the two-dimensional Henon chaotic mapping into the RC4 cipher technology, which improves the RC4 security performance.
