Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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−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.
