A WLAN Anonymous Authentication Scheme Combining EAP-TLS and DAA

By using the hardware TPM in the client end, anonymous identity protection can be achieved to get higher security and better privacy protection. Combining EAP-TLS protocol and ECC-DAA scheme organically, a new anonymous authentication protocol for WLAN is proposed. As Brickell´s and Li´s ECC-DAA is more efficient and reasonable than other existing ones, of which the Join protocol and Sign protocol utilized with corresponding EAP-TLS steps to form new ones with security guaranteed by the ECC-DAA.
