Outsourcing the Decryption of Ciphertexts for Predicate Encryption via Pallier Paradigm
2017With the proliferation of computation and storage outsourcing, access control has become one of the vital problems in cloud computing. Supporting more complex and flexible function, predicate encryption (PE) is gaining more and more attention in access control of decryption outsourcing.

Blockchain-Based CP-ABE with Publicly Verifiable Outsourced Decryption in IoT
2020Attribute based encryption (ABE) was used to ensure confidentiality and access control in IoT as a preeminent cryptographic primitive. However, the traditional ABE with outsourced decryption cannot achieve public verifiability for decryption results. In this paper, blockchain technology is appplied to realize the publicly verifiability in our CP-ABE ...

Decentralized Access Control on Data in the Cloud with Fast Encryption and Outsourced Decryption
2015 IEEE Global Communications Conference (GLOBECOM), 2014Fine grained access control is a requirement for data stored in untrusted servers like clouds. Owing to the large volume of data, decentralized key management schemes are preferred over centralized ones. Often encryption and decryption are quite expensive and not practical when users access data from resource constrained devices.

Requester-Centric CP-ABE Combining Removing Escrow and Outsourcing Decryption
2019Key escrow and low efficiency are two practical bottlenecks of attribute-based encryption. In this paper, a Requester-Centric CP-ABE (RC-CP-ABE) combining removing escrow and outsourcing decryption is proposed. By the bilinear map of composite order, we optimized the computational complexity of key transformation in the case of a large number of ...

The CP-ABE with Full Verifiability Outsourced Decryption and White-Box Traceability
2018In the CP-ABE scheme, the private key is defined on attributes shared by multiple users. For any private key that can not be traced back to the owner of the original key, the malicious users may sell their decryption privileges to third parties for economic benefit and will not be discoverable.
