The invention provides an RFID two-way authentication method. The method comprises: receiving a first parameter C1 sent by a reader/writer, a random number N, a tag account address TAddress and a reader/writer account address RAddress; if the label account address TAddress is stored in the self-maintained block chain, generating the second parameter C2 according to the label account address TAddress, the label account balance balanceBC and the random number N; if it is known that the first parameter C1 is equal to the second parameter C2, Then, determining that the authentication of the tag bythe reader/writer is successful, and according to the balance balanceBC of the tag account and the random number N, generating the third parameter C3 and sending the third parameter C3 to the tag bythe reader/writer, so that the tag obtains the authentication result of the tag/reader based on the third parameter C3. Through combination of the block chain technology and the RFID technology, sincethe block chain is essenti
