Latest Patents
One of Ryuichi Ohori's latest patents focuses on solving multivariate quadratic problems using digital or quantum annealing. This method involves obtaining a set of multivariate quadratic polynomials associated with a multivariate quadratic problem. It generates an Ising Model connection weight matrix 'W' and an Ising Model bias vector 'b' based on these polynomials. The method provides the matrix 'W' and the vector 'b' to an annealing system configured to solve problems written according to the Ising Model, ultimately obtaining an output that represents a set of integers. These integers serve as a solution to the multivariate quadratic problem.
Another notable patent is a method and apparatus for cryptographic data processing. In this invention, a mask is selected from a plurality of masks. A first masked random number is generated by converting a first random number using the selected mask, and a first key is created from this masked random number and a first biometric code derived from biometric information. The mask information indicating the selected mask is stored for future use. A second masked random number is generated using either the same or a different mask, and a second key is created similarly. A ciphertext is then generated using one of the keys and an error-correction encoding method.
