Bounded Fully Homomorphic Signature Schemes

Homomorphic signatures enable anyone to publicly perform computations on signed data and produce a compact tag to authenticate the results. In this paper, we construct two bounded fully homomorphic signature schemes, as follows. – For any two polynomials d = d(λ), s = s(λ), where λ is the security parameter. Our first scheme is able to evaluate any circuit… CONTINUE READING
