A method of performing authentication by an electronic apparatus and an electronic apparatus for performing authentication are provided. The electronic apparatus receives an access request to an application executed on the electronic apparatus, obtain any one of public helper data and private helper data, which are used for user authentication, based on the access requested application, obtain an encryption key from user's biometric information received according to the access request, based on the public helper data or the private helper data by using a fuzzy extractor, and perform user authentication for accessing the application, based on the obtained encryption key.

Method, apparatus, and recording medium for performing authentication

A device for transmitting a packet includes a first processor configured to generate a first packet based on a first content; a second processor configured to generate a second packet independently from the first processor based on a second content; a signaling processor configured to generate a signaling packet based on the first content and the second content; and a communication interface configured to transmit the first packet, the second packet, and the signaling packet, wherein the first processor, the second processor, and the signaling processor respectively generate the first packet, the second packet, and the signaling packet in parallel.

Data transmitting device and method

A method and an apparatus for encoding and decoding in an electronic device are provided. In a decoding method, at least one parity symbol is received.
