By research on typical payment protocol of the PayWord, the paper points out its security problems, and presents a new mobile micropayment protocol based on chaotic Hash function. This protocol generates pay certificate and encrypts order messages transmitted in the network with symmetric encryption algorithm. It also constructs secure chaotic Hash function based on Hénon-like mapping, and creates two payment chains using chaotic Hash function in the protocol, The protocol is not only the anonymous concerning so that the user information which can ensure the confidentiality of the ordered message, but also realizes the partial fairness. Research results demonstrate that the new protocol has greater security and efficiency, and suits to those mobile micropayment transactions systems.
