Service providing client, wireless terminal and method for implementing binding

A wireless terminal, comprising:

• a transmission module, which is configured to transmit authentication information to a service providing client;
• a judgment module, which is configured to judge whether the service providing client is legal according to a response of the service providing client for the authentication information;
• a processing module, which is configured to provide service to the service providing client if both the wireless terminal and the service providing client are legal, and provide no service if the service providing client is illegal;
• a second encryption module, which is configured to encrypt authentication information by using a first encryption algorithm to obtain response information if authentication information transmitted by the service providing client is received;
• and
• a feedback module, which is configured to transmit the response information to the service providing client,
• wherein the service providing client is located in a computing device which performs a communication function through the wireless terminal;
• a random number generation module, which is configured to generate a random number as the authentication information;
• and
• a first encryption module, which is configured to encrypt the random number by using a second encryption algorithm to obtain encryption information;
• wherein the judgment module comprises:
• a first authentication unit, which is configured to judge whether response information of the service providing client for the random number is received;
• a second authentication unit, which is configured to judge whether the response information is consistent with the encryption information if the response information is received;
• and
• a determination unit, which is configured to determine that the service providing client is legal if the response information is consistent with the encryption information, and determine that the service providing client is illegal or the service providing client does not run if the response information is inconsistent with the encryption information or the response of the service providing client is not received,
• wherein the random number generation module and the first encryption module are each the result of execution on a processor of software stored in a memory
• wherein the transmission module, the judgment module, the processing module, the second encryption module, the random number generation module, the first encryption module and the feedback module are each the result of execution on a processor of software stored in a memory.

A method for implementing binding between a service providing client and a wireless terminal, comprising:

• generating a random number as the authentication information by the service providing client;
• and
• encrypting, by the service providing client, the random number by using a first encryption algorithm to obtain encryption information;
• transmitting authentication information to a wireless terminal by a service providing client;
• judging, by the service providing client, whether response information of the wireless terminal for the random number is received;
• judging whether the response information is consistent with the encryption information if the service providing client receives the response information;
• and
• determining, by the service providing client, that the wireless terminal is a legal binding object if the response information is consistent with the encryption information, and determining that the wireless terminal is an illegal binding object if the response information is inconsistent with the encryption information or the wireless terminal does not respond;
• providing service to the wireless terminal by the service providing client if both the wireless terminal and the service providing client are legal, and restricting, by the service providing client, the service provided to the wireless terminal if the wireless terminal is an illegal binding object;
• encrypting authentication information by using a second encryption algorithm to obtain response information if the service providing client receives the authentication information transmitted by the wireless terminal;
• and
• transmitting the response information to the wireless terminal by the service providing client,
• wherein the service providing client is located in a computing device which performs a communication function through the wireless terminal.
