A Cluster of CP-ABE Microservices for VANET
Procedia Computer Science, 2019 Abstract The promising high data rate of a 5G network enables the reality of Vehicular Ad Hoc Networks (VANET). VANETS are ad-hoc networks and they have limited resources. Providing the confidentiality of data by an access control system in a highly dynamic and automated network is a major challenge.

Expressive CP-ABE with partially hidden access structures
Proceedings of the 7th ACM Symposium on Information, Computer and Communications Security, 2012 At Eurocrypt 2005, Sahai and Waters [7] introduced the concept of attribute-based encryption (ABE). ABE enables public key based one-to-many encryption and is envisioned as a promising cryptographic primitive for realizing scalable and fine-grained access control systems.
