Due to the very attack-specific nature of the exploited hiding mechanisms, developing general detection methods is a hard task. An effective approach concerns the creation of ad-hoc solutions to be integrated within general toolkits, also to holistically face unknown threats. Therefore, this paper discusses the integration of a tool for detecting malicious contents hidden in digital images via the Invoke-PSImage technique within the Secure Intelligent Methods for Advanced Recognition of Malware and Stegomalware framework. Since the real impact of images embedding steganographic threats and the behavior of ad-hoc solutions in realistic scenarios are still unknown territories, this work also showcases a performance evaluation conducted in a nation-wide telecommunication provider. Results demonstrated the effectiveness of the approach and also support the need of modular architectures to face the emerging wave of highly-specialized threats.","PeriodicalId":306813,"journal":{"name":"Proceedings of the 17th International Conference on Availability, Reliability and Security","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-08-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121636147","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}

FHE has two types: one supporting the exact computation and the other supporting the approximate computation. Further the FHE schemes supporting the exact computation have two types, bit-wise FHE, which encrypts a plaintext bit by bit, and integer-wise FHE, which encrypts a plaintext as an integer. Both types of FHE are important depending on the types of computation we need to execute securely. In this work, we focus on integer-wise FHE, and propose improved methods for integer-wise homomorphic comparison and division operations. For a comparison operation, we propose a method that halves the number of necessary homomorphic multiplications by introducing an odd function as an interpolated polynomial to be evaluated, as opposed to the previous work of Narumanchi et al. (AINA ’17). For a division operation, as opposed to the previous work of Okada et al. (WISTP ’18), we propose a simple method to reduce the processing time by introducing an equality function based on Fermat’s little theorem without changing the multiplicative depth, and show the analysis of why this approach can achieve better efficiency in detail. In our homomorphic division, the number of interpolated polynomials is reduced by half, thus also achieving the reduction of the processing time of precomputations and the number of polynomials to be stored. We also implement our improved methods in HElib, which is one of popular FHE libraries using the BGV encryption. As a result, we show that, e.g., in the plaintext space , our homomorphic comparison with the Paterson-Stockmeyer method is faster by a factor of about 5.61 compared with Narumanchi et al. (AINA ’17) and our homomorphic division is faster by a factor of about 1.45 compared with Okada et al. (WISTP ’18).","PeriodicalId":306813,"journal":{"name":"Proceedings of the 17th International Conference on Availability, Reliability and Security","volume":"513 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-08-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123408352","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}

Blockchain solutions are used to enhance the trustworthiness and eliminate the need for trusted third parties by providing mechanisms to reach consensus in a network of trustless participants. The consensus algorithms employed by blockchain architectures ensure the integrity of the data stored in the blockchain, the resiliency of the network and manage the security of devices. However, current solutions are compute intensive affecting the performance of the network and consuming much energy. In this work, we introduce a consensus algorithm for offering secure distributed consensus among IoT devices without affecting the performance of the network. The algorithm is inspired by existing solutions, employs decentralised identities, verifiable credentials and a decentralised trust management mechanism to guarantee security, privacy and trustworthiness of transactions. Finally, our algorithm combines technologies for operating in a distributed manner which favors the scalability and allow the effective integration in large scale networks.","PeriodicalId":306813,"journal":{"name":"Proceedings of the 17th International Conference on Availability, Reliability and Security","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-08-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125924040","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}
