Latest Patents

Ryuichi Sakai holds a patent for a key sharing method, secret key generating method, common key generating method, and cryptographic communication method in the ID-NIKS cryptosystem. This patent involves mapping at a point on an elliptic curve, which is utilized for elliptic encryption based on the identity information of each entity. The mapping value is set as the public key of the entity. By using this mapping value along with secret information, a unique secret key for each entity is generated. The entity can then create a common key for encryption and decryption processes by utilizing the self-secret key and the public key derived from the elliptic curve mapping based on the ID information of the communication participant. This method employs pairing on the elliptic curve to enhance security.
