High-speed secret key generation method facing wireless communication

The present invention provides a high-speed secret key generation method facing wireless communication. The method comprises the steps of: the step 1, appointing a generation function G in advance bya legal sender A and a legal sender B; the step 2, sending signals XA to a legal receiver B by the legal sender A, the signals received by the legal receiver B being YB, and sending signals XB to thelegal sender A by the legal receiver B, the signals received by the legal sender A being YA; the step 3, employing the generation function G, the signals YA and the signals XA by the legal sender A togenerate a sharing random source GA, and employing the generation function G, the signals YB and the signals XB by the legal receiver B to generate a sharing random source GB; and the step 4, generating the same secret keys by the legal sender A and the legal receiver B according to the GA and the GB. The high-speed secret key generation method facing wireless communication allow the both legal communication sides to obtai
