Journal ArticleDOI
HASBE: A Hierarchical Attribute-Based Solution for Flexible and Scalable Access Control in Cloud Computing
TL;DR: The security of HASBE is formally proved based on security of the ciphertext-policy attribute-based encryption (CP-ABE) scheme by Bethencourt and its performance and computational complexity are formally analyzed.
Journal ArticleDOI
CrowdBC: A Blockchain-Based Decentralized Framework for Crowdsourcing
TL;DR: A blockchain-based decentralized framework for crowdsourcing named CrowdBC is conceptualized, in which a requester's task can be solved by a crowd of workers without relying on any third trusted institution, users’ privacy can be guaranteed and only low transaction fees are required.
Journal ArticleDOI
Attribute-Based Encryption With Verifiable Outsourced Decryption
TL;DR: This paper gives the formal model of ABE with verifiable outsourced decryption and proposes a concrete scheme that is both secure and verifiable, without relying on random oracles and shows an implementation of the scheme and result of performance measurements, which indicates a significant reduction on computing resources imposed on users.
Journal ArticleDOI
Security and Privacy in Smart Health: Efficient Policy-Hiding Attribute-Based Access Control
TL;DR: PASH is introduced, a privacy-aware s-health access control system, in which the key ingredient is a large universe CP-ABE with access policies partially hidden, and attribute values of access policies are hidden in encrypted SHRs and only attribute names are revealed.
Proceedings ArticleDOI
Efficient and practical fair exchange protocols with off-line TTP
TL;DR: The protocols presented here are the first exchange protocols which use offline TTP and at the same time guarantee true fair exchange of digital messages and introduce a novel cryptographic primitive, called the Certificate of Encrypted Message Being a Signature (CEMBS), as the basic building block of the fair exchange protocols.
