  • Patent number: 9386016
    Abstract: An authentication device receives each authentication context including an output information block, an input information block, and an authenticator block. The output information block includes a process result and process result identification information. The input information block includes a process result and process result identification information. The authentication device verifies each authenticator block. The authentication device searches for the output information block having the same value of process result identification information as the value of process result identification information in the input information block from other authentication contexts based on process result identification information in the input information block included in each authentication context.

  • Publication number: 20140259120
    Abstract: A verification device transmits challenge information to a first entity device, and for each authentication context received in return, verifies that challenge information identical to the challenge information transmitted in advance is described, to thereby confirm that the authentication context is the current one. As a result, a repetitive attack in which the past authentication context is repeatedly used is prevented and the security against repetitive attacks is improved.

  • Patent number: 8732461
    Abstract: A client apparatus receives a message including a random number from a server apparatus during the handshake of agreement process, creates a biometric negotiation message including the biometric authentication method information and sends the biometric negotiation message to the server apparatus. Then, the client apparatus executes a biometric authentication based on biometric authentication method information notified from the server apparatus and encrypts the random number based on the private key. In addition, the client apparatus generates an authenticator from a result of the biometric authentication, the biometric authentication method information, the encrypted random number, and the client certificate, and sends to the server apparatus an authentication context including these. The server apparatus verifies the authentication context and establishes a secure session in one handshake.

  • Patent number: 8599397
    Abstract: According to one embodiment, a deriving operation control device obtains derivation control information and a derivation attribute. A deriving operation propriety determination unit extracts the number of times of previously-performed derivation from the derivation attribute. The deriving operation propriety determination unit extracts the upper limit number of times enabling derivation from the derivation control information and determines that a deriving operation is possible when the number of times of previously-performed derivation is equal to or below the upper limit number of times enabling derivation. A deriving operation execution unit executes the deriving operation.

  • Patent number: 8578446
    Abstract: A configuration including, in authentication contexts, function unit identification information unique to the function unit that has executed an authentication subprocess in entity devices permits an authentication apparatus to specify the function unit that has executed the authentication subprocess in the entity devices. The verifier, therefore, can verify the legitimacy of the authentication subprocess from the authentication context even in the presence of a plurality of function units capable of executing the same authentication subprocess in the entity devices.

  • Patent number: 8499147
    Abstract: A root-account management apparatus generates an electronic signature based on a survival condition and a secret key when an authentication result of a user of a client apparatus is proper, and transmits derived-account credence element information including the survival condition, the electronic signature and a public key certificate to a derived-account management apparatus. The derived-account management apparatus creates derived-account information which becomes valid when the survival condition is satisfied so that the derived-account information includes both the derived-account credence element information which becomes invalid when a validity term of the public key certificate expires and a biometric information template of the user which is valid regardless of this validity term. Accordingly, even if an authentication element as a root (public key certificate) becomes invalid, a derived authentication element (biometric information template) can be prevented from becoming invalid.

  • Patent number: 8281373
    Abstract: A client apparatus transmits environmental information acquired from an environmental information acquisition device as well as a biometric authentication information matching result to a server apparatus. The server apparatus verifies the validity of the environmental information such as a luminance as well as the validity of the biometric authentication information matching result. If an environment is problematic, the server apparatus notifies the client apparatus that the environmental information is problematic. The client apparatus overcomes the problem of the environment such as the luminance based on the notification from the server apparatus and then retries a biometric authentication. The possibility of re-failure due to the environmental problem can be reduced during a retry of the biometric authentication.
