Vulnerabilities of controller that is caused by separation of control and forwarding lead to a threat which attacker can take remote access detection in SDN. The current work proposes a controller architecture called secure control plane (SCP) that enhances security and increase the difficulty of the attack through a rotation of heterogeneous and multiple controllers. Specifically, a dynamic-scheduling method based on Bayesian Stackelberg Games is put forward to maximize security reward of defender during each migration. Secondly, introducing a self-cleaning mechanism combined with game strategy aims at improving the secure level and form a closed-loop defense mechanism; Finally, the experiments described quantitatively defender will get more secure gain based on the game strategy compared with traditional strategy (pure and random strategies), and the self-cleaning mechanism can make the control plane to be in a higher level of security.
RFID (Radio-Frequency IDentification) is attractive for the strong visibility it provides into logistics operations. In this paper, we explore fair-exchange techniques to encourage honest reporting of item receipt in RFID-tagged supply chains and present a fair ownership transfer system for RFID-tagged supply chains. In our system, a receiver can only access the data and/or functions of the RFID tag by providing the sender with a cryptographic attestation of successful receipt; cheating results in a defunct tag. Conversely, the sender can only obtain the receiver's attestation by providing the secret keys required to access the tag.
