Abstract

The present disclosure provides a Bluetooth connection method, the method includes that: a client reads information stored in a Radio Frequency Identification (RFID) card and establishes a Bluetooth connection with a server according to the read information. The present disclosure also provides a Bluetooth connection system, wherein a Bluetooth address and an identification (ID) value of the RFID card are pre-stored in the RFID card; after reading the information stored in the RFID card, the client directly uses a Service Discovery Protocol (SDP) service search to carry out an interaction with the server, achieving automatic completion of a Bluetooth authentication while a Bluetooth service search is performed, thereby establishing a secure and reliable Bluetooth connection; The method significantly reduces the time for establishing a Bluetooth connection, and makes the application of the Bluetooth service more concise and rapid to realize, costing less, more efficient, and easier to popularize.

R), ID*=S(ID), and H(ID*)=H(S(ID)) via a one-way Hash function according to the received R and the read ID; and

sending, by the client, the H(ID) and the H(ID∥

R) to the server;

forwarding, by the server, the H(ID) and the H(ID∥

R) received, as well as the R, to a background database;

forwarding, by the database, the H(ID*_i) to the client through the server; and

comparing, by the client, whether the received H(ID*_i) and the calculated H(ID*) are equal, if so, updating, by the client, the ID in the RFID card to ID*, and determining that the client passes the Bluetooth authentication.

2. The method according to claim 1, further comprising:

before reading, by a client, information stored in an RFID card,

storing a Bluetooth address and an ID of the RFID card in the RFID card.

3. The method according to claim 1, wherein the calculating, by the database, H(ID*_i) according to the received data and a list stored in the database itself is:

determining, by the database, whether there exists an i satisfying H(ID_i)=H(ID) in the list stored in the database itself;

if so, finding, by the database, the ID_i corresponding to H(ID_i), and calculating, by the database, H(ID_i∥

R); and

comparing, by the database, whether the H(ID_i∥

R) and the received H(ID∥

R) are equal;

if so, further calculating, by the database, ID*_i=S(ID_i) and H(ID*_i)=H(S(ID_i)), and sending, by the database, the H(ID*_i) to the server.

4. The method according to claim 3, further comprising:

after sending, by the database, the H(ID*_i) to the server,

determining, by the database, whether an associating pointer in the list corresponding to the calculated H(ID*_i) is 0;

if so, adding a new record;

otherwise, modifying a record pointed to by the associating pointer.

5. The method according to claim 3, further comprising:

after comparing, by the database, whether the H(ID_i∥

R) and the received H(ID∥

R) are equal,

when they are not equal, deciding the current client is an unauthorized terminal.

6. A Bluetooth connection system comprising a Radio Frequency Identification (RFID) card, a client, and a server, wherein

the client is configured to read information stored in the RFID card and establish a Bluetooth connection with the server according to the read information,

wherein the client is configured to carry out a Bluetooth authentication with the server by utilizing a challenge/answer mechanism of a Service Discovery Protocol (SDP) service search and utilizing the RFID according to the read information, and establish the Bluetooth connection when the Bluetooth authentication is successful;

wherein the system further comprises a database;
