A new study has found promising developments in the field of functional encryption (FE), a cryptographic primitive that allows users to learn a specific function of encrypted data while the actual plaintexts remain private. The study, conducted by leading experts in the field, believes that FE will play a crucial role in access control systems, particularly in cloud-based systems, in the years to come.
In the study, the researchers presented two instantiations of a generic FE scheme from the Decisional Diffie-Hellman (DDH) problem that satisfies the property of verifiable decryption. They also presented a novel multi-input FE scheme that can be instantiated from Regev’s cryptosystem and is secure even against quantum adversaries. The study concluded with a multi-party computation protocol that allows the FE construction to be deployed in a multi-client mode.

The authors from our consortium demonstrated the potential of functional encryption to revolutionize the field of access control and privacy protection. Our researchers believe that their work will help to bring FE one step closer to becoming an integral part of cloud-based systems and other access control systems in the future.

This study provides important insights into the current state of the field and the potential for future developments in functional encryption. It is a must-read for anyone interested in cryptography, privacy, and access control.
