In order to solve the problems of enormous keys in Kerberos inter-realm authentication,an authenticated certificateless key agreement protocol is proposed.It can overcome the limitations of original Kerberos authentication.It builds a security inter-realm session key only with one round message exchange,and it provides perfect forward secrecy.Security analysis result shows that the improved protocol can solve key management problem and the interception which can not be proved,and it makes the system more secure.
