Abstract
A method for encrypting data in a near field communication system is provided. The method includes generating encrypted data based on first data input in a current state and second data input in a state immediately preceding the current state, and encoding the encrypted data through a predetermined error correcting code.
Claims20
A method for encrypting data of a terminal in a near field communication system, the method comprising:
- generating encrypted data based on first data input in a current state and second data input in a preceding state of the current state;
- and
- encoding the encrypted data through a predetermined error correcting code.
A method for reconstructing encrypted data of a terminal in a near field communication system, the method comprising:
- decoding encrypted data input in a current state through a predetermined error correcting code;
- and
- reconstructing original data by decrypting a code of the decoded data based on data reconstructed in a preceding state of the current state.
An apparatus for encrypting data in a near field communication system, the apparatus comprising:
- a first encoder configured to generate encrypted data based on first data input in a current state and second data input in a preceding state of the current state;
- and
- a second encoder configured to encode the encrypted data through a predetermined error correcting code.
An apparatus for reconstructing encrypted data in a near field communication system, the apparatus comprising:
- a first decoder configured to decode encrypted data input in a current state through a predetermined error correcting code;
- and
- a second decoder configured to reconstruct original data by decrypting a code of the decoded data based on data reconstructed in a preceding state of the current state.
