20110235806 | Key distribution system - The key distribution system comprises a terminal ( | 09-29-2011 |
20110320621 | COMMUNICATION NETWORK SYSTEM - The communication network system comprises: a relay device ( | 12-29-2011 |
20120096266 | AUTHENTICATION SYSTEM - The authentication system includes a user node, a plurality of service nodes, an authentication database storage unit, an authentication unit, a user info nation database storage unit, and a key distribution unit. Each service node is configured to provide a service corresponding to its domain. The authentication database storage unit is configured to store a secret key of the user node for each domain. The user information database storage unit is configured to store an account used for associating a domain with the user node. The key distribution unit is configured to, upon receiving a domain change request from the user node and then confirming that the user information database stores the account associating the user node with a desired domain to which the user node intends to belong, obtain the secret key of the user node associated with the desired domain from the authentication database storage unit, and send the obtained secret key to the user node. The authentication unit is configured to create a session key, and encrypt the created session key with the secret key corresponding to the desired domain, and send the encrypted session key to the user node. | 04-19-2012 |
20120106735 | ENCRYPTION KEY DISTRIBUTION SYSTEM - The encryption key distribution system includes a node A, a node B, and an authentication server S. Upon receiving a first nonce created by the node A and a second nonce created by the node B, the authentication server S creates a session key. The authentication server S sends a first message authentication code value and a first encryption message to the node A. The first encryption message is created by encrypting the first nonce, the session key, and first additional information with a first secret key. The authentication server S sends a second message authentication code value and a second encryption message to the node B. The second encryption message is created by encrypting the second nonce, the session key, and second additional information with a second secret key. The node A decrypts the first encryption message with the first secret key, thereby obtaining the session key and the first additional information. Further, the node A authenticates the session key by use of the first message authentication code value. The node B decrypts the second encryption message with the second secret key, thereby obtaining the session key and the second additional information. Further, the node B authenticates the session key by use of the second message authentication code value. | 05-03-2012 |
