Research on distributed identity authentication mechanism of IoT device based on blockchain by Chen TAN, Meijuan CHEN, Ebenezer ACKAH Amuah

“…Aiming to solve problems of the low compatibility and weak anti-attack ability of the Internet of things (IoT) centralized platform in the device identity authentication process,a blockchain-based distributed IoT device identity authentication architecture was proposed.The digital identity and related information were stored in the new block data structure,and a distributed IoT device identity authentication mechanism was proposed based on the cryptography related knowledge.At the same time,a device digital certificate issuance process and a detailed process of the identity authentication were designed.The security analysis of the proposed mechanism were carried out from the aspects of power constraints,device privacy protection,and ability to resist attacks among various entities.The performance of three aspects,which were security attributes,computational overhead and storage overhead,were compared and analyzed.The results show that the proposed identity authentication mechanism can resist a variety of malicious attacks,achieve highly secure distributed IoT identity authentication,and has certain advantages in the performance.…”

CBFM:cutted Bloom filter matrix for multi-dimensional membership query by Yong WANG, Xiao-chun YUN, ANGShu-peng WANG, Xi WANG

“…In order to improve the flexibility and accuracy of mu i-dimensional membership query,a new indexing structure called CBFM(cutted Bloom filter matrix)was proposed.CBFM built the bit matrix by the Cartesian product of different bloom filters,each representing one attribute of primary data.In this way,the proposed matrix supported by-attribute membership query.Besides,the attribute combinations in the bit matrix could be reduced and weighted on demand to further enhance memory utilization rate.Theoretical analysis proves that CBFM utilizes memory more effi-ciently than BFM,the current state of art.Experiments also show that,on the scenario of memory size fixed,the false positive rate of CBFM is lower than that of all other indexin ethods.Especially on the scenario of memory constrained,the false positive rate of CBFM can be 3 orders of magnitude lower than that of BFM(Bloom filter matrix) indexing me-thod.CBFM is an accurate data structure for multi-dimensional membership query.…”

Privacy protection scheme for internet of vehicles based on homomorphic encryption and block chain technology by Ruijin WANG, Yucheng TANG, Weiqi ZHANG, Fengli ZHANG

“…In order to solve the problem that the security of traditional internet of vehicles devices is relatively low,which may threaten the privacy of users,a privacy protection scheme based on homomorphic encryption and block chain technology was proposed.This scheme added the authentication service composed of two level nodes to the proposed model to realize the permission control of roles in the model.In order to record the information of the internet of vehicles devices,a new block data structure based on homomorphic encryption (HEBDS) was proposed,which enabled the privacy data to be written into the block after being processed by the Paillier encryption algorithm,and then written into the blockchain network by the gateway node obtaining the accounting right.This scheme realized the data processing in ciphertext state,and made up for the shortage of all data disclosure in blockchain network.Through the analysis of the security of the scheme,it is proved that the scheme has the characteristics of unforgeability and privacy data security.Through homomorphic encryption of privacy data and upload to blockchain network,the scheme can distribute,share and calculate privacy data in ciphertext state,which can protect customer privacy more effectively than traditional internet of vehicles model.…”
