In State Grid, different power companies tend to cooperate to train a global model to predict the risk of the grid or the trustworthiness of the customers in the future. The datasets belonging to each power company should be protected against another corporation, sector or other unauthorized entities, since they are closely related to users' privacy. On the other hand, it is widely reported even the local mode parameters can also be exploited to launch several attacks such as membership inference. Most existing work to realize privacy-preserving model aggregation relies on computationally intensive public key homomorphic encryption(HE) such as Paillier's cryptosystem, which loads intolerably high complexity on resource-constrained local users. To address this challenging issue, in this paper, a lightweight privacy-preserving data aggregation scheme is proposed without utilizing public-key homomorphic encryption. First, an efficient privacy-preserving data aggregation protocol PPDA is proposed based on any one-way trapdoor permutation in the multiple user setting. Then, based on PPDA, a lightweight secure model training scheme LSMT in federated learning is designed. Finally, security analysis and extensive simulations show that our proposed PPDA and LSMT well protect the sensitive data of power enterprises from collusion attacks, guarantees the security of aggregated results, and outperforms existing ones in terms of computational and communication overhead.","PeriodicalId":255083,"journal":{"name":"2023 7th International Conference on Cryptography, Security and Privacy (CSP)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126556633","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Their framework consists roughly of three steps. First, they apply k-means on the iteration traces from multiple ECSM executions, then, the results of clustering are used to make a leakage metric trace by using sum-of-squared t-values (SOST), based on the leakage metric trace, the points of interest (POI) are selected. Second, they apply k-means on those POIs to get initial labels for the scalar bits, the accuracy of initial labels is only 52%. Third, wrong bits are corrected by using an iterative deep learning framework. Our work focus on improving the horizontal attack framework by replacing SOST with our proposed two dimensional SOST (2D-SOST) to improve the efficiency of POI selection under unsupervised context. 2D-SOST can extract leakage information between dimensions while SOST can only extract information on one dimension which limits its performance. By replacing SOST with 2D-SOST, our method improves the accuracy of clustering algorithm from an average of 58% to an average of 74%. We also simplified the framework used in original paper and finally recover scalar bits successfully under the configuration where the original paper can not.","PeriodicalId":255083,"journal":{"name":"2023 7th International Conference on Cryptography, Security and Privacy (CSP)","volume":"99 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128786946","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The corrupted parties can learn the outputs of the honest parties and abort the protocol. Settling for the second best, there are many works focusing on the detection of the cheaters. We construct a SPDZ-like protocol which achieves fairness when at most $n/2$ parties behave maliciously and supports identifiable abort for dishonest majority. We suggest a sharing stage after the parties finish their computation. The parties share the returns of the computation in this stage. The correctness of the sharing is guaranteed by verifiable secret sharing and homomorphic signature. The honest parties can reconstruct the outputs of the cheaters in the setting of an honest majority. We can't prevent the corrupted parties from learning the outputs and aborting the protocol for dishonest majority. Therefore, the sharing stage does not harm to the honest parties. Instead, we provide the honest parties with the identities of all cheaters in this case.","PeriodicalId":255083,"journal":{"name":"2023 7th International Conference on Cryptography, Security and Privacy (CSP)","volume":"106 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128087859","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Due to privacy requirements, data files need to be uploaded after being encrypted. Current searchable encryption technology enables retrieval of encrypted data, but lacks verification of searched results. In response to the above problem, this paper proposes a new searchable encryption scheme based on blockchain, which supports multi-keyword ranked search together with verification of searched results. Concretely, the scheme first encrypts the data and uploads it to the cloud server, then builds the index via blockchain. By calling the smart contracts to execute the search algorithm, the search result is returned to the user and the hash value is verified, which ensures the integrity and accuracy of the searched result. Secondly, by combining the vector space model and BM25 model to construct the index and query of encrypted data, the ranked search for multiple keywords is realized, in which the keyword balanced binary tree index is established to improve the retrieval efficiency. Experimental results show that the improved scheme has higher search accuracy while ensuring retrieval efficiency.","PeriodicalId":255083,"journal":{"name":"2023 7th International Conference on Cryptography, Security and Privacy (CSP)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131071902","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

UAVs network trust secure communication to perform the role objectives, enable and coordinate dispatches. However, more efforts are needed toward security by protecting every entity against malicious attacks in the network. One open challenge in the UAV network lies in keeping bad actors out of the network and enabling security features for highly heterogeneous and resource-hungry devices (sensors, nodes, actuators). To handle that, we design a new practical security scheme to authenticate the legitimacy of peer device connectivity that is lightweight and secure for UAVs network. The proposed protocol provides mutual authentication between UAV and base station devices. We present a formal security verification using the ProVerif tool as well as old-fashioned cryptanalysis to show that the scheme facilitates various security credentials, such as confidentiality, data integrity, identity privacy, etc., and is resilient against well-known security attacks that impersonation, replay, and forwarding security attacks. We also compare our protocol's performance evaluation (of test-bed) results with state-of-the-art authentication protocols for UAVs based on computation costs.","PeriodicalId":255083,"journal":{"name":"2023 7th International Conference on Cryptography, Security and Privacy (CSP)","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124813057","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
