Abstract
A method and apparatus for transmitting data. Data to be transmitted is an aggregated frame including a first subframe and a second subframe each including information used to verify integrity of each subframe, and an apparatus receiving the data verifies integrity of a subframe based on the information used to verify the integrity.
Claims11
A data transmission method to be performed by a transmitting terminal, the method comprising:
- generating a frame header of a plurality of subframes, having a first subframe and a second subframe, to include a first secure frame counter (SFC) value of the first subframe that is used to ensure a uniqueness of a first nonce for the first subframe, wherein the first SFC value is used to generate the first nonce for generating first integrity verification information of the first subframe and used to generate a second SFC value of the second subframe;
- generating the first subframe to include the first integrity verification information;
- generating the second subframe to include second integrity verification information, wherein the second SFC value is used to generate a second nonce for generating the second integrity verification information;
- generating an aggregated frame comprising the frame header, the first subframe, and the second subframe, wherein the first SFC value is a unique SFC value explicitly included in the aggregated frame;
- and
- transmitting the generated aggregated frame to a receiving terminal,
- wherein, in response to the first integrity verification information being verified by the receiving terminal, the integrity of the frame header and the integrity of the first subframe are determined, and the first SFC value in the frame header is used to verify the first integrity verification information, and
- wherein, in response to the second integrity verification information being verified by the receiving terminal, only the integrity of the second subframe is determined.

A transmitting terminal configured to transmit data, the transmitting terminal comprising:
- a processor configured to:
- generate a frame header of a plurality of subframes, having a first subframe and a second subframe, to include a first secure frame counter (SF C) value of the first subframe that is used to ensure a uniqueness of a first nonce for the first subframe, wherein the first SFC value is used to generate the first nonce for generating first integrity verification information of the first subframe and used to generate a second SFC value of the second subframe;
- generate the first subframe to include the first integrity verification information;
- generate the second subframe to include second integrity verification information, wherein the second SFC value is used to generate second nonce for generating the second integrity verification information;
- generate an aggregated frame comprising the frame header, the first subframe, and the second subframe, wherein the first SFC value is a unique SFC value explicitly included in the aggregated frame;
- and
- a communicator configured to transmit the generated aggregated frame to a receiving terminal,
- wherein, in response to the first integrity verification information being verified by the receiving terminal, the integrity of the frame header and the integrity of the first subframe are determined, and the first SFC value in the frame header is used to verify the first integrity verification information, and
- wherein, in response to the second integrity verification information being verified by the receiving terminal, only the integrity of the second subframe is determined.
