Full Verifiability for Outsourced Decryption in Attribute Based Encryption

IEEE Transactions on Services Computing, 2020
Attribute 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.

Attribute-Based Encryption With Efficient Verifiable Outsourced Decryption

IEEE Transactions on Information Forensics and Security, 2015
Attribute-based encryption (ABE) with outsourced decryption not only enables fine-grained sharing of encrypted data, but also overcomes the efficiency drawback (in terms of ciphertext size and decryption cost) of the standard ABE schemes. In particular, an ABE scheme with outsourced decryption allows a third party (e.g., a cloud server) to transform an

Attribute-Based Encryption With Verifiable Outsourced Decryption

IEEE Transactions on Information Forensics and Security, 2013
Attribute-based encryption (ABE) is a public-key-based one-to-many encryption that allows users to encrypt and decrypt data based on user attributes. A promising application of ABE is flexible access control of encrypted data stored in the cloud, using access polices and ascribed attributes associated with private keys and ciphertexts.

CCA-secure ABE with outsourced decryption for fog computing

Future Generation Computer Systems, 2018
Fog 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, 2015
Attribute-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.

Attribute-based encryption with outsourced decryption in blockchain

Peer-to-Peer Networking and Applications, 2020
Attribute-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 ...

Outsourcing Decryption of Attribute Based Encryption with Energy Efficiency

2015 10th International Conference on P2P, Parallel, Grid, Cloud and Internet Computing (3PGCIC), 2015
In this paper, we propose a new efficient scheme to outsource the the decryption of attribute based encryption with energy efficiency. We observe all the previous work on out-sourcing the decryption of ABE cares little about the ciphertext length. Almost all of them have linear length ciphertext with the attributes or the policy.
