Attribute-based proxy signature scheme for unmanned aerial vehicle networks by Lei HE, Jianfeng MA, Dawei WEI

“…It is necessary to use digital signature scheme to protect integrity and authentication of commands sent by command agencies to unmanned aerial vehicle (UAV) in the UAV networks.Moreover, the signature scheme should ensure UAV can receive signature in time and protect privacy of signers.Therefore, an attribute-based proxy signature scheme for UAV networks was proposed and its security was analyzed.The proposed signature scheme has existential unforgeability under selective-attribute and chosen message attacks, and privacy of signers is protected.Its efficiency was analyzed in terms of computation costs and communication costs, and compared with other related signature schemes.The results indicate the proposed signature scheme has less computation costs when its communication costs are at the same level with other signature schemes.…”

Multi-authority attribute-based encryption scheme with policy dynamic updating by Xi-xi YAN, Yuan LIU, Zi-chen LI, Yong-li TANG

“…Attribute-based encryption (ABE) is a new cryptographic technique which guarantees fine-grained access control of outsourced encrypted data in the cloud environment.However,a key limitation remains,namely policy updating.Thus,a multi-authority attribute-based encryption scheme with policy dynamic updating was proposed.In the scheme,an anonymous key issuing protocol was introduced to protect users’ privacy and resist collusion attack of attribute authority.The scheme with dynamic policy updating technique was secure against chosen plaintext attack under the standard model and can support any types of policy updating.Compared to the existing related schemes,the size of ciphertext and users’ secret key is reduced and can significantly reduce the computation and communication costs of updating ciphertext.It is more effective in the practical application.…”

Address overloading-based packet forwarding verification in SDN by Ping WU, Chaowen CHANG, Zhibin ZUO, Yingying MA

“…Aiming at the problem that the most existing forwarding verification mechanisms in software-defined network (SDN) verified packets hop-by-hop by incorporating new secure communication protocols, which incurred significant computation and communication overhead, an address overloading-based forwarding verification mechanism was proposed.The flow runtime was divided into consecutive random intervals by the ingress switch via overloading address fields of packet, basing on overloading address, packets were forwarded by each subsequent switch, and the controller sampled the packets forwarded by ingress and egress switch in the interval to detect abnormal behavior on the path.Finally, the proposed mechanism and simulation network was implemented and evaluated.Experiments show that the mechanism achieves efficient forwarding and effective anomaly detection with less than 8% of additional forwarding delays.…”
