Example Embodiment

[0045]In order to make the purpose, technical solutions and advantages of the present application, the present application will be described in further detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are intended to explain the present application and is not intended to limit the present application.

[0046]As in the conventional technique, the user pays a fee for the product selection, and the product sales direction provides the ciphertext corresponding to the option function. The user can input the ciphertext to the electronic test device. And use this option. Further, the ciphertext will remain in the electronic test equipment. Each time you turn it on, the cipher text is decrypted by the arithmetic control unit of the electronic test device, and the corresponding optional function is turned on. Since the software is decrypted and opened, the hacker has often occurred, and the software ex...

Abstract

The invention relates to an electronic test device and a configuration method of an matching function, and the method comprises the steps: carrying out the decryption authentication operation through a ciphertext decryption authentication unit according to a function optional key and a function optional ciphertext, and carrying out the corresponding operation on a functional device according to an authentication result signal, and enabling the ciphertext decryption authentication unit to output an authentication result signal to the operation control unit, so that the operation control unit operates a target function corresponding to the function selection ciphertext according to the authentication result signal. Visibly, according to the application, the decryption process is transplanted to the ciphertext decryption authentication unit, the security protection performance of the matching function of the electronic test equipment is improved, whether the functional device is started or not is determined according to the result of the decryption authentication operation, a second security mechanism is added for the matching function of the electronic test equipment, and the cracking difficulty of the matching function of the electronic test equipment is greatly improved.

Description

technical field [0001] The present application relates to the technical field of test and measurement, in particular to an electronic test device and a method for configuring optional functions. Background technique [0002] With the development of electronic technology, various electronic devices have appeared. In order to meet the needs of development, design and debugging of electronic equipment, the functions of electronic test equipment are becoming more and more abundant. According to the different needs of users, the electronic test equipment of the same model can provide different optional functions, and the opening of the optional functions requires payment. [0003] In the traditional technology, the user pays the product seller for an optional function, and the product seller provides the user with the ciphertext corresponding to the optional function, and the user enters the ciphertext into the electronic test equipment to open and use the optional function. wi...
