Abstract:
1. A data sharing method, comprising: sending, by a transmitter, an original signal through a noisy channel; receiving, by a receiver, the original signal through the noisy channel to obtain a received signal; defining, by the transmitter, a common dividing policy; dividing, by the transmitter, the original signal into a first signal and a second signal based on the common dividing policy; defining, by the receiver, the common dividing policy; dividing, by the receiver, the received signal into a third signal and a fourth signal based on the common dividing policy, the third signal and the fourth signal being corresponding to the first signal and the second signal; calculating, by the transmitter, a first syndrome message for error correction based on the first signal; sending, by the transmitter, the first syndrome message through a clear channel; receiving, by the receiver, the first syndrome message through the clear channel; calculating, by the receiver, a second syndrome message for error correction based on the fourth signal; sending, by the receiver, the second syndrome message through the clear channel; receiving, by the transmitter, the second syndrome message through the clear channel; decoding, by the transmitter, the second signal by using the second syndrome message to restore the fourth signal; and decoding, by the receiver, the third signal by using the first syndrome message to restore the first signal.
