The ID-based key management system includes an authentication server configured to authenticate a terminal through key exchange based on an ID and a password of a user of the terminal, set up a secure channel with the terminal, and provide a private key based on the ID of the user to the terminal through the secure channel, and a private-key generator configured to generate the private key corresponding to the ID of the terminal user according to a request of the authentication server. | 02-05-2015 |
20160072775 | SYSTEM AND METHOD FOR KEY EXCHANGE BASED ON AUTHENTICATION INFORMATION - Disclosed are a system and method for exchanging a key based on user authentication information. The system for exchanging a key based on user authentication information includes a terminal configured to generate an ID-based ciphertext corresponding to authentication information of a user of the terminal using a terminal-side random number and a server ID and a server configured to decrypt the ID-based ciphertext that is received from the terminal using a server-side private key corresponding to the server ID to restore the authentication information, authenticate the terminal using the restored authentication information, and generate a server-side session key corresponding to the authenticated terminal. | 03-10-2016 |
20160080144 | APPARATUS AND METHOD FOR DATA ENCRYPTION - Provided is an apparatus for encrypting data including a key determiner configured to determine a cipher key for white-box cryptography (WBC)-based encryption and a symmetric key different from the cipher key and an encrypter configured to generate a ciphertext of the data using the WBC-based encryption and symmetric-key-based encryption with the symmetric key. | 03-17-2016 |
