This method is relying on standard Decisional Diffie-Hellman security assumptions and can result in efficient accountable ring signature schemes [4] and proofs of set memberships [5] with a signature size smaller than all existing alternative schemes relying on standard assumptions. This construction also serves as a fundamental building block for numerous recent blockchain privacy protocols including Anonymous Zether [1], [2], Zerocoin [3], Lelantus [11], Lelantus-MW [9], Triptych [14] and Triptych-2 [15]. In this work, we introduce a new method of instantiating one-out-of-many proofs which reduces the proof generation time by an order of magnitude. Our approach still results in shorter proofs comprised of only a logarithmic number of commitments and does not compromise the highly efficient batch verification properties endemic to the original construction.","PeriodicalId":247481,"journal":{"name":"2020 15th Asia Joint Conference on Information Security (AsiaJCIS)","volume":"60 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121115412","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}

In recent years, many studies have explored how to construct PRE schemes that support fine-grained access control for complex application scenarios, such as identity-based PRE and attribute-based PRE. Besides, in order to achieve more flexible access control, the predicate proxy re-encryption (PPRE) is further studied. However, existing PPRE is restricted with the inner product predicate function. Therefore, how to realize the PPRE of arbitrary predicate function is still a problem to be solved. In this manuscript, we propose a secure generic construction of predicate proxy key re-encapsulation mechanism built from a “linear” predicate key encapsulation mechanism. Since the secure key encapsulation mechanism can be used as a building block to construct public key encryption, we can obtain a PPRE from our construction. As a result, the results open up new avenues for building more flexible and fine-grained PPRE.","PeriodicalId":247481,"journal":{"name":"2020 15th Asia Joint Conference on Information Security (AsiaJCIS)","volume":"212 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116068589","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}

Since the pioneering work of Chor et al. (FOCS ‘95) and of Kushilevitz and Ostrovsky (FOCS ‘97), PIR has been extensively studied (especially the single database setting) in the past two decades. However, most protocols only allow users to retrieve only one data at a time, which leads to high communication costs. To solve this issue, this work proposes a multi-value private information retrieval protocol using group homomorphic encryption, which allows users to retrieve multiple values at a time. We compared our work with that of Ostrovsky and Skeith (PKC ‘07) and show that retrieving multiple data at a time significantly can significantly reduces communication costs. Furthermore, we provide rigorous proof that if the underlying group homomorphic encryption is secure, then no attacker can know what data the user has retrieved.","PeriodicalId":247481,"journal":{"name":"2020 15th Asia Joint Conference on Information Security (AsiaJCIS)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124028250","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}

This paper uses 3D-Playfair encryption for encryption. However, simple 3D-playfair encryption cannot guarantee the integrity of data during transmission, so the author proposes Combined with MD5 to ensure the integrity of the data, but there are doubts about the credibility of the data source, so this paper uses XOR calculation methods to further verify the credibility of the data. When a man-in-the-middle attack is encountered, the attacker intercepts the packet And tampering with the data content can still accurately determine whether the source of the data is the original sender. This method guarantees the integrity of the data while improving the credibility of the data.","PeriodicalId":247481,"journal":{"name":"2020 15th Asia Joint Conference on Information Security (AsiaJCIS)","volume":"198 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116168870","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}

In consideration of privacy preserving, users tent to encrypt their files before uploading them to the cloud. Under certain conditions, a file owner may want to share the encrypted files directly on the cloud. In such cases, the file owner will delegate the re-encryption ability to a proxy with re-encryption keys. However, Chen et al. found that the size of the re-encryption key (or condition key) would increase with the number of the conditions, which motivated them in proposing the concept of key-aggregate proxy re-encryption. Unfortunately, we found that the conditions cannot be changed arbitrarily once we set the conditions at the beginning. To solve the problem, we apply the multilinear maps to the key-aggregate proxy re-encryption to extend the number of conditions to be exponentially large, while keeping the size of public parameters small and practical.","PeriodicalId":247481,"journal":{"name":"2020 15th Asia Joint Conference on Information Security (AsiaJCIS)","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125136485","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}
