Non-repudiation of a mobile digital rights management (DRM) ensures that when a user (U) sends some message to a rights issuer (RI), neither U nor RI can deny having participated in this transaction. An evidence of a transaction is generated by wireless PKI mechanism such that U and RI cannot repudiate sending and receiving the message respectively. U generates a mobile agent which carries encrypted payment information to RI. This mobile agent is also issued a proxy certificate by U; this certificate guarantees the binding relationship between them. One trusted third party acts as a lightweight notary for evidence generation. One advantage of this agent-based non-repudiation protocol is to reduce inconvenience for mobile clients such as connection time; it causes difficulty for fair transaction for mobile DRM.
