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.

Chosen Ciphertext Secure Attribute-Based Encryption with Outsourced Decryption
Lecture Notes in Computer Science, 2016Although attribute-based encryption ABE is a useful cryptographic tool to realize expressive access policy on ciphertexts, it is not quite suitable for mobile devices. The root cause lies in that the size of the ciphertext and the decryption cost are usually proportional to the complexity of the access policy.

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.

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 ...

Selective decryption of outsourced IoT data
2015 IEEE 2nd World Forum on Internet of Things (WF-IoT), 2015Outsourcing of IoT-data is a common concept when using third-party services, e.g. an external building management service is given access to the building's sensor measurements. However, the measurements captured from building systems often need to be protected from unauthorized access, because they are linked to persons, processes or business secrets ...
