Abstract: Based on signcryption process of reader and label in the RFID system, this paper proposes a signcryption algorithm based on elliptic curve crypto system, and solves a security problem about asynchronous of encryption and certification in RFID system. The algorithm uses the obscure of elliptic curve crypto system, and has an advantage of DLP design with its shorter key, higher security and flexibility. Most of all, it have a lower communication cost and higherlevel security.
