ABE Squared: Accurately Benchmarking Efficiency of Attribute-Based Encryption

Transactions on Cryptographic Hardware and Embedded Systems, 2022
Measuring efficiency is difficult. In the last decades, several works have contributed in the quest to successfully determine and compare the efficiency of pairing-based attribute-based encryption (ABE) schemes. However, many of these works are limited:

Attribute-based encryption for circuits [PDF]

Proceedings of the forty-fifth annual ACM symposium on Theory of Computing, 2013
In an attribute-based encryption (ABE) scheme, a ciphertext is associated with an ℓ-bit public index ind and a message m , and a secret key is associated with a Boolean predicate P .

Multiauthority Attribute-Based Encryption With Dynamic Membership From Lattices

IEEE Access, 2022
Attribute-based encryption is useful for one-to-many encrypted message sending. However, most attribute-based encryption schemes authorize and issue attributes to users by a single authority.

Revocable Ciphertext-Policy Attribute-Based Encryption in Data Outsourcing Systems from Lattices

Jisuanji kexue yu tansuo, 2020
Attribute-based encryption mechanism is widely used in outsourcing environment because of its charac-teristics of “one-to-many” communication. However, users attributes often change dynamically.

How to Hide the Real Receiver Under the Cover Receiver: CP-ABE With Policy Deniability

IEEE Access, 2020
Attribute-based encryption (ABE) is a useful tool for sharing an encrypted data to a target group. In a ciphertext-policy ABE (CP-ABE) scheme, a ciphertext includes a policy to indicate its receivers and only those receivers can correctly decrypt the ...

Two-dimensional Code Hierarchical Encryption Algorithm Based on Attribute Encryption [PDF]

Jisuanji gongcheng, 2018
The two-dimensional code is only suitable for the transmission of single privilege information,cannot meet the needs of different permission users to gain the information.Using hierarchical encryption mode,the two-dimensional code information is ...

An enhanced media ciphertext-policy attribute-based encryption algorithm on media cloud

International Journal of Distributed Sensor Networks, 2020
With the development of cloud computing, more and more video services are moving to the cloud. How to realize fine-grained access control of those data on cloud becomes an urgent problem. Attribute-based encryption provides a solution.

Efficient Compressed Ciphertext Length Scheme Using Multi-Authority CP-ABE for Hierarchical Attributes

IEEE Access, 2018
In an attribute-based encryption, the user is identified with help of some attributes and their functions for encryption and decryption of the data. The current techniques based on attribute-based encryption have found that if user's access structure ...
