Calibration method, elevator control device, and elevator peripheral device

Abstract

A verification method, an elevator control device, and an elevator peripheral device. The elevator control device comprises a master control board (1), and a first microprocessor (11) and a first encryption chip (12) are provided on the master control board. The verification method comprises: a first microprocessor (11) generates a first random number and separately sends the first random number to the first encryption chip (12) and a peripheral device; the first encryption chip (12) performs encryption operation on the first random number by using a first encryption algorithm and a first key to obtain first ciphertext data and sends the ciphertext data to the first microprocessor (11); and the first microprocessor (11) compares the received first ciphertext data with second ciphertext data received from the peripheral device, and if the first ciphertext data is the same as the second ciphertext data, confirms that the peripheral device is valid. The provision of an encryption chip having a key in the elevator control device and the elevator peripheral device separately, and the use of an asymmetric algorithm for further encrypting the devices improve device verification effectiveness.

Description

Technical field [0001] The present invention relates to the field of electronic technology, and more specifically, to a verification method, elevator control equipment and elevator peripheral equipment. Background technique [0002] During the long-term use of the elevator, it is necessary to regularly perform replacement of damaged parts, debugging and maintenance, etc. to ensure the long-term safe use of the elevator. Generally, the elevator factory that sells the elevator is responsible for the maintenance or the designated maintenance company is responsible for the maintenance and maintenance of its elevator system. [0003] However, more and more informal manufacturers use illegal means to compete for the maintenance benefits of elevators, such as: privately replacing the damaged parts of the original elevator, and illegally maintaining the original elevator at a low price. However, because the source of the accessories is unknown, it is difficult to guarantee the quality of ...

Problems solved by technology

ID binding is based on ID storage. Pirated software and hardware cannot be used because the ID cannot be matched.

[0005] However, in the above software protocol encryption method, because the data can be captured on the bus, it is easy to crack the encryption protocol through the algorithm analyzer, and the running program in the core main controller is also easy to crack and obtain the running program. source code for
