A typical approach to guarantee the authentication of the public key holderrelies on a trusted agent named Certificate Authority (CA). Digital signaturebased CA binds entity's identity, ID, to the corresponding public key, KU.However, in the mobile business, the CA not only adds the system's complexitybut also increases the user charge. Therefore, it is infeasible to applysignature scheme based CA in mobile business. In this paper, an ID-basedsignature scheme for mobile business is put forward. In the signature scheme,the public key is ID of the mobile user or it can be obtained by ID so that theuser does not need to access the CA to obtain the public key. This feature isespecially desirable for transaction-type mobile applications such as mobilebusiness. The implementation result in the mobile station such as mobile phoneis also illustrated in the paper. It is clear that the signature scheme caneffectively provide the non-repudiation service for mobile business.
