Based between sdn trusted domain security authentication protocol

SDN-based inter-trusted domain security authentication protocol belongs to the field of information security. The invention will be trusted network ideas into OpenFlow network architecture under the SDN concept to achieve future network architecture credible and controllable security objectives. On the basis of the establishment of a trusted domain, we propose a non-trusted third party between trusted domain security authentication protocol, the protocol uses challenge-response mode, first of all, trusted network access authentication supplicant into the initial state, and is requester sends identity information, is to make a response requester, return their identity, the identity registered with each other. Second, the authentication requester with the requester to continue using the challenge-response mode negotiation credible sensitive information, by comparing the results of the hash value and sensitive information PCR random number, a trust certification. Finally, if the requester with the requester respective comparison hash results meet the requirements of credibility, authentication is successful. Otherwise, mutual trust and authentication fails.
