A main concern in the public key distribution is the authenticity of the public key. Authenticating public keys provides assurance to the entity that the received public key corresponds to the sender’s identity. A typical approach to guarantee the authentication of the public key holder relies on a trusted agent named Certificate Authority (CA). The signature based CA binds entity’s identity ID to the corresponding public key KU. However, in the mobile payment system, the CA not only adds the system’s complexity but also increase the user charge. Therefore, it is the worst security problem in the mobile payment systems that there is no signature so that the non-repudiation service can not effectively be protected. In this paper, an ID-based signature scheme for mobile payment is put forward. In the signature scheme, the public key is the ID of the mobile user or can be obtained by the ID so that the user does not need to access the CA to obtain the public key. This feature is especially desirable for transaction-type mobile applications such as mobile payment. Therefore, the signature scheme can effectively provide the non-repudiation service for mobile payment.
