Enhanced Ciphertext-Policy Attribute-Based Encryption (ECP-ABE)

2019
Cloud computing becomes an open environment which provides an opportunity for integrating additional capacity, or new features, into existing systems on dynamic provisioning of computing resources with minimal management costs in an optimal way. Initially, public keys are replaced with arbitrary strings which act as an identity in Identity Based ...

Deploying parallelised ciphertext-policy attributed-based encryption in clouds

International Journal of Computational Science and Engineering, 2018
In recent years, cloud storage has become an attractive solution due to its elasticity, availability and scalability. However, the security issue has started to prevent public clouds becoming more popular. Traditional encryption algorithms (both symmetric and asymmetric ones) fail to support achieving effective secure cloud storage due to severe issues

New Ciphertext-Policy Attribute-Based Encryption with Efficient Revocation

2014 IEEE International Conference on Computer and Information Technology, 2014
Attribute-based encryption (ABE) is getting popular for its fine-grained access control in cloud computing. However, dynamic user or attribute revocation is a challenge in original ABE schemes. To address this issue, a new cipher text-policy ABE scheme with efficient revocation is proposed.

Ciphertext-Policy Attribute-Based Encryption and Re-Encryption

A ciphertext-policy attribute-based encryption system, comprising a re-encrypter (9) for cryptographically transforming a first ciphertext (CTp1) associated with a first access policy (P1) into a second ciphertext (CTP2) associated with a second access policy (P2) by means of a re-encryption key (RK).

A Provably Secure Ciphertext-Policy Hierarchical Attribute-Based Encryption

2015
With the booming growth of network technology, the problems of information disclosure are becoming more and more serious. The attribute-based encryption has been one of hotspots for the advantage of fine-grained access control. In this paper, a provably secure ciphertext-policy hierarchical attribute-based encryption is proposed, which can satisfy the ...
