Federated learning based intelligent edge computing technique for video surveillance by Yu ZHAO, Jie YANG, Miao LIU, Jinlong SUN, Guan GUI

“…With the explosion of global data,centralized cloud computing cannot provide low-latency,high-efficiency video surveillance services.A distributed edge computing model was proposed,which directly processed video data at the edge node to reduce the transmission pressure of the network,eased the computational burden of the central cloud server,and reduced the processing delay of the video surveillance system.Combined with the federated learning algorithm,a lightweight neural network was used,which trained in different scenarios and deployed on edge devices with limited computing power.Experimental results show that,compared with the general neural network model,the detection accuracy of the proposed method is improved by 18%,and the model training time is reduced.…”

Blockchain data sharing scheme based on localized difference privacy and attribute-based searchable encryption by Tao FENG, Liqiu CHEN, Junli FANG, Jianming SHI

“…Aiming at the problem that traditional cloud-based data sharing schemes rely on trusted third parties and only focus on data privacy protection or access control, a blockchain data sharing scheme based on localized difference privacy and attribute-based searchable encryption was proposed.The blockchain and cloud server were combined to store data chain by chain and provide efficient, reliable and tamper-proof data sharing.Firstly, the localization difference privacy was introduced to preprocess the shared data to protect the privacy of the data owner and resist the attack of the untrusted third party.Secondly, the searchable encryption technology and attribute-based encryption were combined to realize data privacy protection, support ciphertext retrieval, and provide fine-grained access control for shared data.Finally, the safety, the correctness proof, and the experimental analysis proves that the proposed scheme meets the safety objectives.…”

Attribute-based proxy re-encryption scheme with multiple features by Chaosheng FENG, Wangping LUO, Zhiguang QIN, Ding YUAN, Liping ZOU

“…A ideal proxy re-encryption scheme has five features,such as one-way encryption,non-interaction,repeatability,controllability and verifiability.The existing schemes,however,have only two or three of the five features,which reduces the utility of them to some extent.For this,a new ciphertext-policy attribute-based proxy re-encryption (CP-ABPRE) scheme with the above five features was proposed.In the proposed scheme,the cloud proxy server could only re-encrypt the ciphertext specified by the delegator by using the re-encryption key,and resist the collusion attack between the user and the proxy satisfying the re-encryption sharing policy.Most of encryption and decryption were outsourced to cloud servers so that it reduced the computing burden on the user’s client.The security analysis show that the proposed scheme resists the selective chosen plaintext attack (SCPA).…”

Multi-authority ABS supporting dendritic access structure by Ruo MO, Jian-feng MA, Xi-meng LIU, Qi LI

“…Attribute-based signature (ABS),which could realize fine-grained access control,was considered to be an important method for anonymous authentication in cloud computing.However,normal ABS only provided simple access control through threshold structure and thus could not cope with the large-scale attribute sets of users in the cloud.Moreover,the attribute sets were supervised by only one attribute authority,which increased the cost of computation and storage.The whole system was in danger of collapsing once the attribute authority was breached.Aiming at tackling the problems above,a novel scheme,was proposed called multi-authority ABS supporting dendritic access structure which supported any AND,OR and threshold gates and affords more flexible access control.Meanwhile,the attribute sets of users were classified by diverse attribute authorities which reduced the overhead and the risk of systems.Besides,the scheme is proved to be selective predicate chosen message attack secure in the random oracle model.…”
