In addition, a specific protocol distributing a hierarchi- cal key after the proactive authentication from key holder to base station has been proposed. The proposed hybrid authenti- cation framework not only performs proaetive authentication with credentials based on Chameleon hashing, which removes the authentication procedures that exchanges messages with a authentication server, but also performs re-authentication with EAP re-authentication protocol（ERP） that distributes the hierarchical key on the basis of the root key generated by the pro- active authentication.展开更多
