Abstract:

We put forth a new notion of distributed public key functional encryption. In such a functional encryption scheme, the secret key for a function f will be split into shares (mathsf {sk}_i^f). Given a ciphertext (mathsf {ct} ) that encrypts a message x, a secret key share (mathsf {sk}_i^f), one can evaluate and obtain a shared value (y_i)....More
