Provided are a networking system for data transmission in a host supporting quality assurance of hyper-precision communication services (HPSs), and more particularly, to a networking method and apparatus in a host of a networking system supporting quality assurance of HPSs. The networking method includes receiving a request for an HPS from a client, checking a descriptor of the HPS in a quality-of-service (QoS) profile of the HPS requested by the client, applying a performance parameter, and selecting an optimal algorithm suitable for a type of the HPS requested by the client.

Data transmission processing networking method and apparatus in a host supporting quality assurance of hyper-precision communication services

Disclosed herein are an apparatus and method for user authentication based on multiple pieces of biometric information. The apparatus may include one or more processors and executable memory for storing at least one program executed by the one or more processors. The at least one program receives multiple pieces of biometric information from the client device of a user, generates the personal identifier of the user using a neural network and a Bloom filter algorithm, and checks the similarity between the personal identifier of the user and each of personal identifiers previously registered in a database, thereby authenticating the user.

Apparatus and method for authenticating user based on multiple biometric information

Disclosed herein are an apparatus and method for recommending privacy control. A privacy control server includes multiple common privacy control recommendation models learned based on personal information provision histories of multiple users, a user preference determination unit for generating at least one question item based on the multiple common privacy control recommendation models and determining a privacy control preference of a user based on a result of a user answer to the at least one question item, and a common privacy control recommendation model provision unit for providing a common privacy control recommendation model selected to match the privacy control preference of the user to the user.

Apparatus and method for recommending user privacy control

Disclosed herein are a terminal apparatus, a server apparatus, and a method for FIDO universal authentication using a blockchain. The method includes sending, by the terminal apparatus, a FIDO service request for any one of FIDO registration, FIDO authentication, and FIDO deregistration for an application service provided by the server apparatus to the server apparatus; verifying, by the blockchain, a FIDO service response message, which is created as a result of local authentication of a user in the terminal apparatus in response to the FIDO service request; and processing, by the server apparatus, the FIDO service request based on whether the FIDO service response message is successfully verified by the blockchain.

Disclosed herein are an apparatus and method for authenticated key exchange using a password and an identity-based signature, by which robustness is provided in order to prevent a server impersonation attack when a password is exposed, and by which a client may be provided with convenient authentication using an ID and a password.

Method and apparatus for authenticated key exchange using password and identity-based signature

Exemplary embodiments of the present invention relate to a batch verification method for verifying a plurality of authentication data or digital signature values and an apparatus thereof. A batch verification method according to an embodiment of the present invention comprises: rearranging N pairs of individual instances which compose a batch verification instance; selecting N&#x2212;1 verification exponents from a verification exponent set E which is used for the batch verification; and performing the batch verification for the rearranged batch verification instance by using the selected verification exponents. Exemplary embodiments of the present invention can be suitable for digital signature and cryptographic confirmation. According to exemplary embodiments, verification computation amount of a plurality of authentication data or digital signature values can be significantly reduced.

Batch verification method and apparatus thereof

Disclosed herein are an apparatus and method for anonymity-based authentication and key agreement capable of providing a communication message binding property. The apparatus includes a signature verification unit and a binding checking unit. The signature verification unit receives a plurality of messages, each carrying a signature including link information of a sender, and verifies the signature of each of the plurality of messages. The binding checking unit, if it is determined by the signature verification unit that the signature is valid, determines whether the plurality of messages has been sent by an identical sender based on the link information of the signature.

Apparatus and method for anonymity-based authentication and key agreement capable of providing communication message binding property

A dynamic multi-dimensional code generation and recognition apparatus in which time information and visual recognition information are combined, and a method thereof are provided. According to the present invention, a dynamic multi-dimensional code or a time-variant code including visual recognition information which is associated with source information and changed over time is provided. Accordingly, users may easily ascertain existence of the multi-dimensional code and intended contents of the source information.

Apparatus and method for dynamic multi-dimensional codes with time and visual recognition information

Disclosed herein is a method of verifying key validity and a server for performing the method. The method is configured such that a service provision server verifies key validity in an anonymous service for providing local linkability. The service provision server receives a revocation list. A local revocation list is generated using the received revocation list and a secret key. A virtual index of a service user required to verify key validity is calculated. Whether a key of the service user is valid is verified, based on whether the virtual index is included in the local revocation list.

Method of verifying key validity and server for performing the same

The present invention relates to a content protection apparatus and method using binding of additional information to an encryption key. The content protection apparatus includes an encryption unit for creating an encryption key required to encrypt data requested by a user terminal and then generating encrypted data in which the data is encrypted. An additional information management unit manages additional information including authority information about the encrypted data. A White-Box Cryptography (WBC) processing unit generates a WBC table required to bind the encryption key corresponding to the encrypted data to the additional information. A bound data generation unit generates bound data in which the encrypted key is bound to the additional information, using a cipher included in the WBC table.
