  • Initializing server configurations in a data center
    Patent number: 11258661
    Abstract: A system for configuring a data center includes a fabric management server coupled to a management switch. A provisional Software Defined Networking (SDN) controller executing on the fabric management server can discover physical servers coupled to the management switch, receive network interface configuration information from the physical servers, and use the discovered network interface configuration information to determine a configuration for switches and servers coupled to an IP fabric. The configuration can be migrated to a full functionality SDN controller.
    Type: Grant

  • User authentication system and method for the same
    Patent number: 8595816
    Abstract: At the user authentication apparatus 30, an identifier of a certification authority (CA) certificate that a CA information disclosure server 20 discloses in advance is registered in an identifier list of the CA. At the user terminal 10, a key pair consisting of a terminal public key and a terminal secret key is generated, the terminal signature is generated for information containing the terminal public key using the CA secret key acquired in advance, and a self-signed certificate of the same form as the certificate issued from CA, that is, a terminal certificate containing at least a terminal public key, a terminal signature, and a CA identifier, is created and stored, and registered in the user authentication apparatus 30.

  • Common key setting method, relay apparatus, and program
    Patent number: 8291231
    Abstract: A secret key of a second apparatus is stored in a relay apparatus. A first apparatus specifies secret information used to identify a common key, generates encrypted secret information by encrypting the secret information by using a public key of the second apparatus, and transmits the encrypted secret information to the relay apparatus. Then, the relay apparatus decrypts the encrypted secret information by using the secret key of the second apparatus to extract the secret information. The relay apparatus transmits the encrypted secret information to the second apparatus. The second apparatus decrypts the encrypted secret information by using the secret key of the second apparatus to extract the secret information. Finished messages corresponding to communication log information and the secret information are exchanged between the first apparatus and the relay apparatus and between the second apparatus and the relay apparatus.
