Efficient and Secure Outsourcing Scheme for RSA Decryption in Internet of Things
IEEE Internet of Things Journal, 2020Rivest–Shamir–Adleman (RSA) is one of the widely deployed public-key algorithms. Yet, its decryption facet is very time consuming for resource-constrained Internet-of-Thing (IoT) devices, as it is based on the modular exponentiation of a large number. Although several variants of RSA have been designed to accelerate decryption, the outcomes have been ...

Attribute-Based Encryption with Publicly Verifiable Outsourced Decryption
2019Attribute-based encryption (ABE) is a useful cryptographic primitive for access control and fine-grained sharing on encrypted data. However, the main drawback of ABE is that the computational cost grows linearly with the complexity of the access policy. One of the promising solutions for the problem is to outsource computation securely.

Offline/online attribute‐based encryption with verifiable outsourced decryption
Concurrency and Computation: Practice and Experience, 2016SummaryIn this big data era, service providers tend to put the data in a third‐party cloud system. Social networking websites are typical examples. To protect the security and privacy of the data, data should be stored in encrypted form. This brings forth new challenges: how to allow different users to access only the authorized part of the data ...

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.

A BGN Type Outsourcing the Decryption of CP-ABE Ciphertexts
2017Cloud computing security is the key bottleneck that restricts its development, and access control on the result of cloud computing is a hot spot of current research. Based on the somewhat homomorphic encryption BGN and combined with Green’s scheme that proposed outsourcing the decryption of CP-ABE (Ciphertext-Policy Attribute-Based Encryption ...

Attribute-Based Encryption With Parallel Outsourced Decryption for Edge Intelligent IoV
IEEE Transactions on Vehicular Technology, 2020Edge intelligence is an emerging concept referring to processes in which data are collected and analyzed and insights are delivered close to where the data are captured in a network using a selection of advanced intelligent technologies. As a promising solution to solve the problems of insufficient computing capacity and transmission latency, the edge ...

Attribute-based encryption with encryption and decryption outsourcing
2014In this paper we propose a new scheme for ciphertext-policy attribute-based encryption that allows outsourcing of computationally expensive encryption and decryption steps. The scheme constitutes an important building block for mobile applications where both the host and users use mobile devices with limited computational power. In the proposed scheme,

Chosen Ciphertext Secure Attribute-Based Encryption with Outsourced Decryption
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.

Fully Secure ABE with Outsourced Decryption against Chosen Ciphertext Attack
2021Attribute-based encryption (ABE) provides fine-grained access control on encrypted data, but it is not suitable for limited-resource devices due to the inefficiency of decryption. To solve this problem, Green et al. proposed a new paradigm named attribute-based encryption with outsourced decryption (OD-ABE).

Flexible Authorization by Generating Public Re-decryption Trapdoor in Outsourced Scenarios
2011 IEEE 4th International Conference on Cloud Computing, 2011With the rapid application of service-oriented technologies, service and data outsourcing has become a practical and useful computing paradigm. Combined use of access control and cryptography was proposed by many researchers to protect sensitive information in this outsourcing scenario.
