Abstract
The invention relates to systems, methods, network devices, and machine-readable media for improved constructions of public-key functional encryption schemes for quadratic functions. In particular, the present disclosure relates to a new functional encryption scheme to compute quadratic functions so that the data owner controls what can be computed but is not involved in the calculation, and generates a decryption key which allows one to learn a quadratic function evaluation of some encrypted data.
