Patent Images
1. 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.
