Privacy-enhancing attribute-based credential (Privacy-ABC) technologies use different cryptographic methods to enhance the privacy of the users. This results in important practical differences between these technologies, especially with regard to efficiency, which have not been studied in depth, but is necessary for assessing their suitability for different user devices and for highly dynamic scenarios. In this paper, we compare the computational efficiency of two prominent Privacy-ABC technologies, IBM's Idemix and Microsoft's U-Prove, covering all known Privacy-ABC features. The results show that overall presentation is in general is more efficient with Idemix, whereas U-Prove is more efficient for the User side (proving) operations during the presentation, and overall when there are more attributes in a credential. For both technologies we confirmed that inspectability, non-revocation proofs, and inequality predicates are costly operations. Interestingly, the study showed that equality predicates, the number of attributes in a credential, and attribute disclosure are done very efficiently. Finally, we identified a number of specific trust issues regarding Privacy-ABC technologies.

PurposeCoronavirus Disease 2019 (COVID-19) necessitated the need for “Hospital-at-home” improvisations that involve wearable technology to classify patients within households before visiting health institutions. Do-It-Yourself wearable devices allow for the collection of health data leading to the detection and/or prediction of the prevalence of the disease. The sensitive nature of health data requires safeguards to ensure patients’ privacy is not violated. The previous work utilized Hyperledger Fabric to verify transmitted data within Smart Homes, allowing for the possible implementation of legal restrictions through smart contracts in the future. This study aims to explore privacy-enhancing authentication schemes that are operated by multiple credential issuers and capable of integration into the Hyperledger ecosystem.Design/methodology/approachDesign Science Research is the methodology that was used in this study. An architecture for ABC-privacy was developed and evaluated.FindingsWhile the privacy-by-design architecture enhances data privacy through edge and fog computing architecture, there is a need to provide an additional privacy layer that limits the amount of data that patients disclose. Selective disclosure of credentials limits the number of information patients or devices divulge.Originality/valueThe evaluation of this study identified Coconut as the most suitable attribute-based credentials scheme for the Smart Homes Patients and Health Wearables use case Coconut user-centric architecture Hyperledger integration multi-party threshold authorities public and private attributes re-randomization and unlinkable revelation of selective attribute revelations.

“…Considering this aspect as well as the provision of privacy properties (recall Section 3.4), Section 6.3 discusses the feasibility of each ABC technique in the considered use cases. For this assessment, we have adopted the framework for evaluation of Privacy-ABC technologies proposed in [56]. We enhance this framework by considering additional criteria particularly useful for understanding the potential of ABCs in VANETs.…”

“…For the sake of simplicity, we did not use all of the criteria described in [56], but only those elements that were common for the three technologies and which we considered to be suitable for the scenarios we have chosen. Particularly, we evaluated the time taken for system setup, issuance, as well as time to do a presentation, which is split into two parts, namely proving, which happens at the User side (in our case, on the vehicle), and verification, which is done by the verifier (in our case, by the Central ITS Station).…”

Smart cities involve the provision of advanced services for road traffic users. Vehicular ad hoc networks (VANETs) are a promising communication technology in this regard. Preservation of privacy is crucial in these services to foster their acceptance. Previous approaches have mainly focused on PKI-based or ID-based cryptography. However, these works have not fully addressed the minimum information disclosure principle. Thus, questions such as how to prove that a driver is a neighbour of a given zone, without actually disclosing his identity or real address, remain unaddressed. A set of techniques, referred to as Attribute-Based Credentials (ABCs), have been proposed to address this need in traditional computation scenarios. In this paper, we explore the use of ABCs in the vehicular context. For this purpose, we focus on a set of use cases from European Telecommunications Standards Institute (ETSI) Basic Set of Applications, specially appropriate for the early development of smart cities. We assess which ABC techniques are suitable for this scenario, focusing on three representative ones-Idemix, U-Prove and VANETupdated Persiano systems. Our experimental results show that they are feasible in VANETs considering state-of-theart technologies, and that Idemix is the most promising technique for most of the considered use cases.
