Data aggregation scheme based on SDN for internet of things by Bowei WANG, Jin TAN, Wenbin JIANG

“…There are many redundant parts in the data generated and transmitted by IoT devices.Transmitting this data reduces network lifetime and bandwidth.Aiming at the problem,the aggregation gateway layer was proposed,and a SDN-based IoT data aggregation architecture and algorithm were designed.The simulation analysis shows that compared with the architecture of the ordinary gateway and OF-GW,the network lifetime is improved by about 32.6%,and the amount of data packets sent by the sensing layer to the network layer is reduced by 6.1% to 55.1%.Compared with the LEACH algorithm,the designed rule algorithm reduces the average delay of data aggregation by about 24.1%,while avoiding data loss and improving the accuracy of data aggregation.…”

Privacy-preserving access control for public wireless LAN utilizing the bitcoin blockchain by Yukun NIU, Lingbo WEI, Chi ZHANG, Xia ZHANG, Vejarano Gustavo

“…In designing an access control scheme for public wireless LAN (WLAN),user privacy protection and user accountability are two conflict goals.A novel user management and access control scheme was proposed to solve this problem by utilizing the bitcoin blockchain and Intel SGX.It utilized unmodified bitcoin blockchain to manage the ownership of access credentials for users without relying on any trusted third party.It adopted Intel SGX-based mixing technology to enhance anonymity of users’ access credentials.It designed verification path rule to resolve the conflicts between the privacy-preserving and accountability objectives.The effectiveness and feasibility of the proposed scheme are also demonstrated by security analysis and performance evaluation.…”

Cross-domain authentication scheme based on consortium blockchain by Jianlin NIU, Zhiyu REN, Xuehui DU

“…To solve the security problems of traditional cross-domain authentication schemes, such as single point of failure and excessive dependence on third parties, a cross-domain authentication scheme was proposed which combines IBC and consortium blockchain.The consortium blockchain was introduced into the cross-domain authentication scene by designing the layered cross-domain authentication architecture including entity layer, proxy layer, blockchain layer and storage layer.In the storage layer, abstract data format was designed and stored in the chain, and the complete data corresponding to the abstract data was stored in the interplanetary file system under the chain.This safe and reliable on-chain distributed storage scheme solved the limitation problem of on-chain storage caused by introduction of blockchain.Besides, an identity management scheme based on permanent autonomy identity and temporary identity was proposed to solve the challenges that it is difficult to cancel identity and to supervise anonymous identity after combining IBC system.On this basis, complete cross-domain full authentication, re-authentication and key negotiation protocols were designed to implement the cross-domain authentication process.In terms of security, SVO logic was used to analyze the authentication protocol, and the security of the cross-domain authentication protocol was proved.The performance of calculation overhead, communication overhead and consortium blockchain were tested and analyzed by simulation.Analysis results showed that the protocol satisfies the security requirements and has improved calculation overhead performance on both server and client sides, comparing with other related works.In terms of communication overhead, it also has better performance.The query/write latency was tested by the consortium blockchain tool, and the results showed that the scheme has good usability.…”
