A self-healing key distribution scheme enables the non-revoked users with the received broadcast messages and their private information to recover the missed group session keys on their own without requiring the group manager to retransmit the missed broadcast messages. In this paper, we construct a new structure to broadcast message to realize the self-healing key distribution. It is shown that the proposed scheme realizes the properties such as constant storage, forward secrecy and backward secrecy. Moreover, the proposed scheme has the property of long life-span of the user's personal secret key, so that the user's personal secret key is not restricted to a fixed sessions in the setup phase and can be used until the user revoked from the group. Finally, we will present that the proposed scheme is more practical and efficient than some existing schemes.
