The invention discloses a method for safely starting special service by terminal equipment. The invention aims to ensure that the terminal equipment can safely start different services to meet the requirements of different scenes.
The technical scheme adopted by the invention for realizing the purpose of the invention is as follows: the method relates to a PC, a terminal device and a set of rules for judging whether a service starting request passes, wherein the PC and the terminal device can communicate through a network. The PC is responsible for sending a request for starting a special service to the terminal equipment through the network; the terminal device is responsible for receiving and parsing the request. If the request can meet the corresponding rule, the terminal equipment opens the corresponding service, otherwise, the terminal equipment refuses to open the service. The method can safely open the corresponding service and effectively prevent external network attack.
The rule for starting the special service request by the equipment terminal relates to an initial key, the format of a request message, the format of the rule and a service rule mapping table. Wherein:
the initial key is used to encrypt the request message.
The format of the request message includes the following: request sequence number, PC equipment MAC address, terminal equipment MAC address, service name, next message decryption key and sending timestamp.
The format of the rules includes the following: the number of request messages, the time interval for each message transmission.
Each service corresponds to a different rule, so the number of request messages and the time interval corresponding to each service are different.
As shown in fig. 1, the PC and the terminal device share an initial password and a service rule mapping table, which may be updated periodically.
The process of sending a service opening request by a PC is specifically as follows:
a1, PC according to the business name to find the corresponding rule in the business rule mapping table, to obtain the message quantity N and time interval T1 needed to be sent;
a2, PC uses the initial password to encrypt the first message, and sends out; simultaneously starting a timer and randomly generating a key for encrypting the next message;
a3, after the time interval T1, the sending time stamp of the message is updated, 1 is added to the request, the new message is encrypted by the key randomly generated in the previous step and then sent out; simultaneously randomly generating a key for encrypting the next message;
and A4, repeating the step A3 until the request process is finished after N request messages are sent.
As shown in fig. 2, the process of receiving, analyzing and opening the service request by the terminal device is specifically as follows:
b1, starting to monitor the request message; when a request message is received, firstly, decrypting the message by using an initial password; if the decryption is successful and the request serial number is 1, searching a corresponding rule in a service rule mapping table according to the service name, and storing the obtained random password for decrypting the next request message;
b2, setting overtime time T2 according to rules, if the time exceeds T2 and the request message is not received, judging that the request fails;
b3, continuing to receive the request message, and when receiving the next request message, decrypting the message by using the random password obtained last time, and simultaneously storing a new random password;
and B4, repeating the step B3, and when the number of the received request messages meets the corresponding rule requirements, checking the time stamp of each message and calculating the time interval. If the time interval, the MAC address and the request sequence number are all right and the time T2 is not exceeded, the request is successful, and the terminal opens the corresponding service.
When the terminal equipment judges whether a service needs to be started, a service rule mapping table needs to be searched; and each rule is composed of the number of request messages sent and the interval of sending messages.
The message sent by the PC needs to be encrypted, the encryption key of the subsequent message is different from that of the previous message, and the encryption keys of the subsequent message are randomly generated. The sending time interval of the front and back messages is obtained by subtracting the time stamps in the message contents.
