Abstract
A method for performing computation of a function over encrypted data by a computation entity is provided. According to the method, the computation of a quadratic function is performed by the computation entity, the encrypted data are encrypted by a linearly homomorphic encryption scheme, and a homomorphic message authentication code is used for providing verifiable computation on encrypted data.
