It is generally believed harmful to have transmission errors in the wireless communications. The high decoding complexity of dense parity check codes is unfavorable. This paper proposes to apply these two "negative" facts to enable the secrecy sharing with the information theoretical security. We claim that the secrecy sharing is always possible if the wiretap channel is not error-free, regardless of the main channel performance. Particularly, the proposed secrecy sharing protocol can provide provable and testable security using the existing wireless technologies.
