Shared data refining device and shared data refining method |
摘要 |
Each of a transmitter ( 1 ) and a receiver ( 2 ) divides temporarily-shared data into one or more purification blocks and one or more disposable blocks, and mixes each purification block so as to enlarge a Hamming distance between corresponding purification blocks being held by the transmitter ( 1 ) and the receiver ( 2 ) by using a Hamming distance amplification effect. The transmitter ( 1 ) Vernam-encrypts the mixed data with the disposable data and transmits the mixed data to the receiver ( 2 ), and the receiver ( 2 ) decrypts the received Vernam-encrypted data by using a disposable block owned thereby, and compares the Hamming distance between the purification block owned thereby with the mixed data with a predetermined value so as to judge whether each purification block can be shared between the transmitter ( 1 ) and the receiver ( 2 ). |
