A signature control method implemented by a computer, the signature control method including: acquiring, by a processor circuit of the computer, a plurality of pieces of document information and signature information that corresponds to each piece of document information of the plurality of pieces of document information; generating, by the processor circuit of the computer, aggregate signature information obtained by aggregating the signature information that corresponds to the each piece of document information of the plurality of acquired pieces of document information on a basis of the plurality of acquired pieces of document information; and outputting, by the processor circuit of the computer, the generated aggregate signature information in association with aggregate public key information obtained by aggregating public key information that corresponds to the each piece of document information of the plurality of pieces of document information and the plurality of pieces of document information.

A method may include obtaining a set of multivariate quadratic polynomials associated with a multivariate quadratic problem and generating an Ising Model connection weight matrix 'W' and an Ising Model bias vector 'b' based on the multivariate quadratic polynomials. The method may also include providing the matrix &#x201c;W&#x201d; and the vector &#x201c;b&#x201d; to an annealing system configured to solve problems written according to the Ising Model and obtaining an output from the annealing system that represents a set of integers. The method may also include using the set of integers as a solution to the multivariate quadratic problem.
