Detailed Description
The technical solution of the present invention is described in detail below.
The invention relates to a set top box-based earthquake early warning information issuing safety tamper-proof method, which comprises the following steps:
step 1, defining a communication protocol between the earthquake early warning issuing system and the set top box, wherein the communication protocol comprises the steps of stipulating that authentication information needs to be provided when the set top box is connected with the earthquake early warning issuing system, storing the authentication information of all the set top boxes in the earthquake early warning issuing system, and stipulating the format of the earthquake early warning information when the earthquake early warning issuing system sends the earthquake early warning information to the set top box. The communication protocol definition has the function that the earthquake early warning issuing system and the set-top box can understand information sent by the other side, and is the basis of information issuing.
And 2, the set top box initiates a connection request to the earthquake early warning issuing system.
And 3, judging whether the connection request contains authentication information by the earthquake early warning issuing system, if so, entering the step 4, and otherwise, rejecting the connection request.
And 4, judging whether the authentication information in the connection request belongs to the authentication information stored in the earthquake early warning issuing system or not by the earthquake early warning issuing system, if so, agreeing to the connection request, and entering the step 5, otherwise, rejecting the connection request.
And 5, when an earthquake occurs, encrypting the earthquake early warning information by the earthquake early warning issuing system, and sending the earthquake early warning information to the set top box in a specified earthquake early warning information format.
And 6, the set top box verifies and decrypts the earthquake early warning information, and when the verification is passed and the decryption is successful, the step 7 is carried out.
And 7, the set top box judges whether the format of the earthquake early warning information which passes the verification and is decrypted successfully is a specified format, if so, the user is prompted through an earthquake early warning interface, and if not, the earthquake early warning information is shielded.
In the above method, in step 1, in order to ensure that the identifier of each set top box is unique, the authentication information of the set top box may be a secret key recorded when the set top box leaves a factory, and the unique card number of the external CA card that cannot be modified or inserted into the read-only memory unit of the set top box.
In steps 1 and 7, in order to provide the most effective prompt for the user when an earthquake occurs, the specified earthquake early warning information is preferably in the format of: the location of the epicenter, the magnitude of the earthquake, and the moment of origin.
In the steps 2 and 3, if the times of the illegal terminal initiating the connection request to the earthquake early warning system reach the specified times, the IP address of the illegal terminal is added into the blacklist of the earthquake early warning system and is automatically shielded, so that the illegal terminal can be prevented from being maliciously invaded.
In step 6, in order to ensure the safety and reliability of the earthquake early warning information, the specific process of checking the earthquake early warning information by the set top box is as follows: the set top box receives the earthquake early warning information and the check code corresponding to the earthquake early warning information, MD5 operation is carried out on the earthquake early warning information to obtain a calculated check code, the calculated check code is compared with the received check code, if the calculated check code is consistent with the received check code, the earthquake early warning information is indicated to be correct, a decryption process is carried out, otherwise, the earthquake early warning information is indicated to be wrong, and the earthquake early warning information is directly discarded. Since MD5 can ensure that any content change in a message, such as a word change, will result in a completely different MD5 value, illegal information cannot be verified by MD5 after content modification. Here, other verification methods may also be used to ensure that the earthquake early warning information is not illegal.
The specific process of decrypting the earthquake early warning information by the set top box is as follows: the set top box executes a decryption algorithm to restore the verified earthquake early warning information into an original text, and if decryption fails, the verified earthquake early warning information is directly discarded.
In order to achieve the purpose of more obviously reminding the user when an earthquake occurs, the step 1 may further include: and defining a template of the earthquake early warning interface, wherein the template can be stored in an early warning system, the set-top box acquires or stores the template in a read-only storage unit of the set-top box from a server side when needing displaying, and the storage mode of the template must meet the requirements that the set-top box is read-only and can not be modified. Therefore, in step 7, the earthquake early warning interface can prompt the user through the template.
