Abstract
A method for verifying information includes receiving a proof for a function to be evaluated from a proofer which has computed an output of the function. The proof is based on an evaluation key generated based on the function and a security parameter. Validity of the proof is verified based on a verification key generated based on the function and the security parameter. The function is defined as a mapping between matrix groups over a finite field and encoded into a polynomial that is described and implemented as an arithmetic circuit. The function to be evaluated is encoded such that the polynomial is a trace of a difference between the product of left and right input matrix polynomials of all gates of the arithmetic circuit and the output matrix polynomial of all gates of the arithmetic circuit.
