PIRATTE: Proxy-based Immediate Revocation of ATTribute-based Encryption
Access control to data in traditional enterprises is typically enforced through reference monitors. However, as more and more enterprise data is outsourced, trusting third party storage servers is getting challenging. As a result, cryptography, specifically Attribute-based encryption (ABE) is getting popular for its expressiveness. The challenge of ABE is revocation. To address this challenge, ...
متن کاملZigBee Security Using Attribute-Based Proxy Re-encryption
ZigBee Network is enabling technology for home automation, surveillance and monitoring system. For better secure network environment, secure and robust security model is important. The paper proposes an application, attribute-based proxy reencryption on ZigBee networks. The method can distribute the authority to designated sensor nodes to decrypt re-encrypted ciphertext with associated attribut...
متن کاملKey Policy Attribute-based Proxy Re-encryption and RCCA Secure Scheme
Cloud computing has come into our daily lives. The cloud server can provide powerful computing and storage capability as services. Since the decryption algorithm for attribute-based encryption needs a lot of computations, so with the help of cloud servers many attribute-based encryption schemes are designed for practical applications in cloud computing. To the best of our knowledge there does n...
متن کاملSecure Outsourced Attribute-based Encryption
Attribute-Based Encryption (ABE) is a promising cryptographic primitive which significantly enhances the versatility of access control mechanisms. Due to the high expressiveness of ABE policies, the computational complexities of ABE key-issuing (by Attribute Authorities (AAs)) and decryption (by eligible users) are getting prohibitively high. Despite that the existing Outsourced ABE solutions a...
متن کاملAttribute-Based Proxy Re-Encryption with Keyword Search
Keyword search on encrypted data allows one to issue the search token and conduct search operations on encrypted data while still preserving keyword privacy. In the present paper, we consider the keyword search problem further and introduce a novel notion called attribute-based proxy re-encryption with keyword search (ABRKS), which introduces a promising feature: In addition to supporting keywo...
