Latest Patents
One of Wijik Lee's latest patents is a functional encryption system and method of performing functional encryption. This system includes a key generation device that creates a public key and a secret key based on a master key and a parameter vector. An encryption device generates encrypted data by encrypting an input vector using the public key. Additionally, a decryption device produces decrypted data corresponding to an approximation value of an inner product of the parameter vector and the input vector. This innovative approach reinforces data security and mitigates attacks from quantum computers by introducing random noise in the decrypted data through functional encryption utilizing the Learning With Errors (LWE) problem and the lattice problem.
Another notable patent is an authentication method and system that employs biometric information and functional encryption. This method involves generating a master secret key and a master public key, as well as creating a secret key and a public key using personal information from the enrollment target. The system communicates the secret key and first information to an authentication server, where it securely stores this data. The authentication process includes calculating the similarity between enrollment and authentication target personal information by computing the Euclidean distance, ensuring a robust verification process.
