Latest Patents

One of Vadim's latest patents is titled "Method for performing a disjunctive proof for two relations." This invention relates to a method for performing a disjunctive proof for two relations, R and R. The relation R is defined between an instance set X and a witness set W, which establishes a language L(R) containing elements x in X for which there exists a witness w that is related to x according to R. The method allows for the generation of a challenge from a simulated challenge c using a bijective function, enabling the prover to demonstrate knowledge of a witness w for at least one of the instances x and x, where b is 0 or 1.

Another significant patent is "Computation using lattice-based cryptography." This invention describes a method for conducting multi-party electronic computation using multiple evaluating computer systems. The cryptographic security of this computation is achieved through lattice-based cryptography. Each evaluating computer system receives individual input shares from users and checks the commitments to these shares, generating a first lattice-based zero-knowledge proof to validate the commitments.
