Full Verifiability for Outsourced Decryption in Attribute Based Encryption
IEEE Transactions on Services Computing, 2020Attribute based encryption (ABE) is a popular cryptographic technology to protect the security of users’ data. However, the decryption cost and ciphertext size restrict the application of ABE in practice. For most existing ABE schemes, the decryption cost and ciphertext size grow linearly with the complexity of access structure.

CCA-secure ABE with outsourced decryption for fog computing
Future Generation Computer Systems, 2018Fog computing is not a replacement but an extension of cloud computing for the prevalence of the Internet of Things (IoT) applications. In particular, fog computing inserts a middle layer named fog into the infrastructure of cloud computing to obtain the low latency, mobility and location-awareness.

Revisiting Attribute-Based Encryption With Verifiable Outsourced Decryption
IEEE Transactions on Information Forensics and Security, 2015Attribute-based encryption (ABE) is a promising technique for fine-grained access control of encrypted data in a cloud storage, however, decryption involved in the ABEs is usually too expensive for resource-constrained front-end users, which greatly hinders its practical popularity.

IEEE Transactions on Dependable and Secure Computing, 2016
Attribute-based encryption (ABE) provides a mechanism for complex access control over encrypted data. However in most ABE systems, the ciphertext size and the decryption overhead, which grow with the complexity of the access policy, are becoming critical barriers in applications running on resource-limited devices.

The CP-ABE with Full Verifiability Outsourced Decryption and White-Box Traceability
Lecture Notes in Computer Science, 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.

Pay as You Decrypt: Decryption Outsourcing for Functional Encryption Using Blockchain
IEEE Transactions on Information Forensics and Security, 2020The concept of functional encryption (FE) has been introduced to address the shortcomings of public-key encryption (PKE) in many emerging applications which require both data storage and data sharing (e.g., cloud storage service). One of the major issues existing in most FE schemes is the efficiency, as they are built from bilinear pairings of which ...

Attribute-based encryption with outsourced decryption in blockchain
Peer-to-Peer Networking and Applications, 2020Attribute-based encryption (ABE) is a powerful cryptographic primitive for access control and fine-grained sharing on encrypted data. Due to this functionality, ABE is usually adopted in encrypted cloud storage for flexible data sharing. However, the main drawback of ABE is that the computational cost grows linearly with the complexity of the access ...
