Abstract
A method of generating prevention and control data to verify validity of data to be transmitted, and an apparatus to perform the method, the method including generating the prevention and control data according to composing information of the data to be transmitted, and transmitting the prevention and control data along with the data to be transmitted to verify the validity of the data to be transmitted.
Claims36
An apparatus to generate prevention and control data to verify validity of data, the apparatus comprising:
- a prevention and control data generating unit to generate composing information of data to be transmitted, and to compose the prevention and control data with verification data generated from the generated composing information;
- an encryption unit to encrypt the data to be transmitted;
- and
- a data transmitting unit to compose transmitting data with the prevention and control data from the prevention and control data generating unit and the encrypted data from the encryption unit, and to transmit the transmitting data to a receiver.
A method of generating prevention and control data to verify validity of data, the method comprising:
- generating composing information of data to be transmitted;
- generating the prevention and control data based on the composing information;
- generating verification data by squaring values of the composing information;
- and
- composing the prevention and control data with the generated composing information and the verification data.
An apparatus to verify prevention and control data to verify validity of data, the apparatus comprising:
- a data receiving unit to receive the prevention and control data, which is composed with composing information of data to be transmitted at a transmitter, and to receive transmitted verification data, generated based on the composing information, from the transmitter;
- and
- a validity check unit to verify the validity of received data by calculating verification data from the composing information of the received data and comparing the calculated verification data and the received verification data from the transmitter.
A method of verifying prevention and control data to verify a validity of a data, the method comprising:
- receiving the prevention and control data, which is composed with composing information of data to be transmitted, and transmitted verification data, generated based on the composing information, from a transmitter;
- calculating verification data from the composing information in the received data;
- and
- verifying the validity of the received data by comparing the calculated verification data and the received verification data.
