Security control scheme for cloud data copy based on differential privacy model by Jun REN, Jin-bo XIONG, Zhi-qiang YAO

“…In cloud computing environment,adversary may use data deduplication as a side channel to eavesdrop users’ privacy.In order to tackle this serious issue,a secure copy number control scheme was proposed.The highlights of the proposed scheme lie in constructing a hybrid cloud framework.Then file was encrypted for second times by using the privacy protection parameters of differential privacy as well as the key of the file computed by convergent encryption algorithm.After the file is uploaded,each file has only one copy in the server.Meanwhile,compared with the scheme that use setting threshold value to control the number of copies,the proposed scheme can resist against the side channel attack,related files attack,and the specific attack of encryption algorithm and save the network bandwidth and disk storage space.…”

Intelligent forecasting and monitoring of air index based on big data and internet of things by Yan LIU, Yong-ping ZHANG, Cheng ZHU, Jun GAO, Qi-ming LIU

“…Air quality forecast has become an urgent need.However,numerical forecast of air quality is a complex systems engineering.The intelligent forecasting of air index was studied from the perspective of big data and intelligent decision making.For the index prediction of air quality,the popular classification algorithm was introduced to realize the intelligent analysis of historical data.To obtain air quality information in real time,a monitoring system based on Internet of Things was established,and intelligent processing of real-time data collected by the classification algorithm was achieved.Due to the large amount of historical air index data and real-time data collected,the technology of cloud computing and big data was introduced to speed up the data processing and improve the storage of data.In addition,the client based on Android was developed to allow users to query the air quality anytime,anywhere.…”

Cloud data secure deduplication scheme via role-based symmetric encryption by Jinbo XIONG, Yuanyuan ZHANG, Youliang TIAN, Zuobin YING, Qi LI, Rong MA

“…The rapid development of cloud computing and big data technology brings prople to enter the era of big data,more and more enterprises and individuals outsource their data to the cloud service providers.The explosive growth of data and data replicas as well as the increasing management overhead bring a big challenge to the cloud storage space.Meanwhile,some serious issues such as the privacy disclosure,authorized access,secure deduplication,rekeying and permission revocation should also be taken into account.In order to address these problems,a role-based symmetric encryption algorithm was proposed,which established a mapping relation between roles and role keys.Moreover,a secure deduplication scheme was proposed via role-based symmetric encryption to achieve both the privacy protection and the authorized deduplication under the hierarchical architecture in the cloud computing environment.Furthermore,in the proposed scheme,the group key agreement protocol was utilized to achieve rekeying and permission revocation.Finally,the security analysis shows that the proposed role-based symmetric encryption algorithm is provably secure under the standard model,and the deduplication scheme can meet the security requirements.The performance analysis and experimental results indicate that the proposed scheme is effective and efficient.…”

Dynamic multi-keyword searchable encryption scheme by Chenghao YUAN, Yong LI, Shuang REN

“…Users of cloud storage often outsource their data to cloud servers to save local storage resources.However, cloud storage data is out of the user’s physical control, which may lead to malicious theft or disclosure of private data on cloud.At present, dynamic searchable encryption schemes are mostly based on symmetric searchable encryption, which need to establish a secure key sharing channel in advance, and cannot be directly applied to data sharing in cloud storage scenarios.For the secure sharing scenario of multi-party data in cloud storage, a dynamic multi-keyword searchable encryption scheme was proposed.The forward index was constructed by a cuckoo filter to enable data owners to perform documents and index dynamic updates.The conjunctive multi-keywords search was supported by combining bilinear pairing with Lagrangian interpolation polynomials.To reduce the computational overhead in the ciphertext retrieval phase, a combination of inverted index and forward index was constructed to improve the retrieval efficiency of cloud server.This scheme is provably secure with the indistinguishability in adaptively chosen keyword attack under decision linear Diffie-Hellman problem.Simulation experiments were conducted to analyze the execution efficiency of the scheme for keyword search and index update in different datasets.The results show that the scheme effectively avoids the linear correlation between the retrieval time and the number of ciphertexts, and reduces the computational overhead in the update operation with a large amount of data.…”
