Attribute-based signature (ABS) is a new cryptographic primitive, in which a signer can sign a message with his attributes, and the verifier can only known whether the signer owns attributes satisfying his policy. Moreover, the signature cannot be forged by any user not having attributes satisfy...
This brings a huge workload to compute a signature and also a threat to security and privacy if the central authority is compromised. In this paper, we present an outsourced decentralized multi-authority attribute based signature (ODMA-ABS) scheme. Compared with existing multi-authority attribute ...
Also, the addition of this scheme with a blind signature is proposed to preserve the confidentiality of the device attributes from the CA. The introduction gives a definition and a brief historical overview of attribute-based encryption (ABE), addresses the use of ABE in the Internet of Things...
White-Box Traceable Ciphertext-Policy Attribute-Based Encryption Supporting Any Monotone Access Structures In a ciphertext-policy attribute-based encryption (CP-ABE) system, decryption keys are defined over attributes shared by multiple users. Given a decryption... Z Liu,Z Cao,DS Wong - 《IEEE Tr...
Mosaicis a library doing Attribute Based Encryption (ABE). It is meant to be used as a example of a cryptographic core to be embedded in any solution willing to rely on an ABE scheme of this kind (a Multi-Authority CipherText-Policy scheme, see below). ...
Attribute-Based Access Control for Multi-Authority Systems with Constant Size Ciphertext in Cloud Computing In most existing CP-ABE schemes, there is only one authority in the system and all the public keys and private keys are issued by this authority, which inc... Y Chen,L Song,Y Geng ...
Some attribute-based encryption techniques have been proposed to achieve more secure data access control for sharing data in a semi-trusted cloud storage system with multiple attribute authorities. However, based on Dolev–Yao model, security goals such as active attack resistance, confidentiality, ...

An efficient reusable attribute-based signature scheme for mobile services with multi access policies in fog computing 2022, Computer Communications Citation Excerpt : The analysis of transmission scheduling and computation offloading strategy for fog-assisted cloud computing can be referred to [51]. The...
The proposed authentication is issued from a new online-offline attribute-based signature. It can make the encrypted PHRs resist collusion attacks and not be forged during the period of sharing, which enhances patients' control to their PHRs. Online-offline and outsourcing decryption also reduces ...
