In this paper, nn innovative and practical authentication system, Anonymous micropayments authentication (AMA), is designed for micropayments in mobile data network. Through AMA the customer and the merchant can authenticate each other indirectly, at the same time the merchant doesn't know the customer's real identity. A customer can get fast micropayemts not only from his local domain but also from a remote domain without increasing any burden on his mobile phone/smartcard. Furthermore, without increasing communication overheads in the air, computational overheads on the mobile phone/smartcard, which usually has limited computational capability and storage, is minimized.
