Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer and clearer, the present invention is further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
The current popular mode for entering the television developer mode is a certificate authentication mode, a certificate has no time limit, can be used infinitely, and is easy to flow out after being used for a long time, so that general personnel can also enter the developer mode, and the security of a television software system can be threatened.
Aiming at the situation, the invention provides a method for unlocking a television developer mode, which defines the service life of a certificate, a secret key is encrypted and decrypted by utilizing an RSA signature technology, a private key is generated by using OpenSSL, an encrypted certificate file is generated according to the certificate application information of an applicant, the intelligent television checks and compares the certificate file, the applicant who meets the requirement is granted the developer mode authority of the intelligent television, and the safety of an intelligent television software system is greatly ensured.
Fig. 1 is a flowchart illustrating a preferred embodiment of a method for unlocking a television developer mode according to the present invention, which comprises the following steps:
and S100, encrypting the certificate application information according to the application developer mode by the system to generate a certificate file and issuing an applicant.
Specifically, in this embodiment, the method specifically includes the following steps:
the system extracts application developer mode personnel information, television system information and certificate application time as certificate application information;
encrypting the certificate application information by using a private key;
and performing base64 encoding on the encrypted certificate application information to obtain an encrypted certificate file, and then issuing the encrypted certificate file to an applicant.
The specific process of generating the encrypted certificate file is shown in fig. 3, which is a flowchart of generating the certificate file according to the preferred embodiment of the method for unlocking the television developer mode of the present invention, the television system sets the certificate generating end to extract the certificate application information, encrypts the certificate application information by using a private key, then encrypts the encrypted certificate application information by using the RSA signature technology, and finally encodes the encrypted certificate file by using base64 to form the encrypted certificate file.
The certificate application information comprises applicant information, television system information, certificate application time, certificate type and certificate service life. The certificate types comprise a developer certificate L1, a tester certificate, a production certificate, an after-sale certificate and a developer certificate L2, wherein the developer certificate L1 is suitable for development engineers of smart television manufacturers, and the developer certificate L2 is suitable for third-party application developers.
After the applicant of the certificate fills in the application information, the certificate generation system can automatically endow the applicant with the service life and the certificate type of the certificate according to the information of the applicant, and the certificate application time is also automatically generated according to the system time, so that the reliability of the certificate is ensured. Then the certificate generation system packs the information and encrypts the information into a certificate file according to the encryption process and sends the certificate file to an applicant. For the use of the television system, different applicants own different types of certificates, and the use time of the certificates of different types is different, so that the functions and the time used by different applicants are distinguished in the certificate generation stage.
Step S200, the system verifies the application timeliness of the certificate according to the encrypted certificate file of the applicant and then determines whether to grant the developer authority.
Specifically, in this embodiment, a workflow of certificate terminal verification is as shown in fig. 4, where the workflow of certificate terminal verification is in a flowchart of a preferred embodiment of the method for unlocking a television developer mode according to the present invention. For the certificate verification process, the smart television firstly needs to be connected with a network, the applicant needs to read the certificate by the television system, in the actual operation process, after the applicant performs the step S100, the applicant can store the encrypted certificate file in the usb disk, then insert the usb disk containing the encrypted certificate file into the smart television, and the smart television system performs base64 decoding on the encrypted certificate file in the usb disk, and then decrypts the encrypted certificate file by using the public key to obtain the plaintext content of the encrypted certificate file.
And the intelligent television system acquires terminal information of the intelligent television, wherein the terminal information comprises television system information, system time and system software compiling time.
