RFID Anti-Collision Algorithm Merging Security Mechanism

Leading into the Code-Division Multiple Access technology is the new hot spot in RFID research. The CDMA has advantages of high security, interference immunity and so on, Hash function has irreversibility in the bidirectional authentication, we improve CDMA technology and combine with hash operation to resolve RFID anti-collision. The algorithm has high security and low cost, it very adapts to the low-middle RFID system.
