The communication security issue is of great importance and should not be ignored in backbone optical networks which is undergoing the evolution toward software defined networks (SDN). With the aim to solve this problem, this paper conducts deep analysis into the security challenge of software defined optical networks (SDON) and proposes a so-called security-enhanced signaling scheme of SDON. The proposed scheme makes full advantage of current OpenFIow protocol with some necessary extensions and security improvement, by combining digital signatures and message feedback with efficient PKI (Public Key Infrastructure) in signaling procedure of OpenFIow interaction. Thus, this security-enhanced signaling procedure is also designed in details to make sure the end-to-end trusted service connection. Simulation results show that this proposed approach can greatly improve the security level of large-scale optical network for Energy Internet services with better performance in term of connection success rate performance.

Route randomization is an important research focus for moving target defense which seeks to proactively and dynamically change the forwarding routes in the network. In this paper, the difficulties of implementing route randomization in traditional networks are analyzed. To solve these difficulties and achieve effective route randomization, a novel route randomization approach is proposed, which is implemented by adding a mapping layer between routers' physical interfaces and their corresponding logical addresses. The design ideas and the details of proposed approach are presented. The effectiveness and performance of proposed approach are verified and evaluated by corresponding experiments.
