Zusammenfassung: | The present invention relates to technology to increase a distillation rate using an advantage distillation protocol which utilizes error correction capability of a repetition code, which is one of secret key distillation processes. According to the present invention, a security key distillation method comprises the step of: setting an error correction threshold of bit error correction capability of a repetition code in a repetition code protocol between a sender and a receiver; and distilling a security key using an advantage distillation protocol, which maximizes the amount of information between the sender and the receiver by setting the error correction threshold. Accordingly, key distillation efficiency can be improved.
본 발명은 보안키 추출(secret key distillation)의 과정 중 하나인 반복 부호(repetition code)의 오류정정능력(error correction capability)을 활용한 이점 증류 프로토콜(advantage distillation protocol)을 이용하여 증류 효율(distillation rate)을 높이는 기술에 관한 것으로서, 송신자와 수신자 간의 반복 부호 프로토콜에서 반복 부호(repetition code)의 비트 오류정정능력(error correction capability)의 오류정정 임계값을 설정하는 단계 및 상기 오류정정 임계값을 설정하여 상기 송신자와 상기 수신자 간의 정보량을 최대화하는 이점 증류 프로토콜(Advantage Distillation Protocol)을 이용하여 보안키를 추출하는 단계를 포함한다. |
