Abstract
A distributed key-based encryption system comprises a sending side and a receiving side. The sending side comprises a key-data generation unit, an encryption unit, a first wireless-transfer unit, and a second wireless-transfer unit. The receiving side comprises a third wireless-transfer unit, a fourth wireless-transfer unit, and a decryption unit. The communication between the second wireless-transfer unit and the fourth wireless-transfer unit is directional.
Claims10
A distributed key-based encryption system comprising a sending side and a receiving side, wherein:
- the sending side comprises:
- a key-data generation unit generating at least one key data;
- an encryption unit generating an encryption data according to a data and the key data;
- a first wireless-transfer unit, which is coupled to the encryption unit and transfers one of the encryption data and the key data;
- and
- a second wireless-transfer unit, which is coupled to the encryption unit and transfers the other one of the encryption data and the key data;
- and
- the receiving side comprises:
- a third wireless-transfer unit receiving one of the encryption data and the key data transferred by the first wireless-transfer unit;
- a fourth wireless-transfer unit receiving the other one of the encryption data and the key data transferred by the first wireless-transfer unit;
- and
- a decryption unit, which is coupled to the third wireless-transfer unit and the fourth wireless-transfer unit, and decrypts and reproduces the encryption data into the data according to the encryption data and the key data,
- wherein a data length of the key data corresponds to a data length of the data.
A distributed key-based encrypt method, comprising:
- generating at least one key data;
- generating an encryption data according to a data and the key data;
- transferring one of the encryption data and the key data through a first wireless-transfer unit;
- transferring the other one of the encryption data and the key data through a second wireless-transfer unit;
- receiving one of the encryption data and the key data through a third wireless-transfer unit;
- receiving the other one of the encryption data and the key data through a fourth wireless-transfer unit;
- decrypting and reproducing the encryption data into the data according to the encryption data and the key data,
- wherein a data length of the key data corresponds to a data length of the data.
