Verification method, elevator control equipment and elevator peripheral equipment

Abstract

The invention provides a verification method, elevator control equipment and elevator peripheral equipment, and is applied to the elevator control equipment. The elevator control equipment comprises amain control board, and a first microprocessor and a first encryption chip are arranged on the main control board. The verification method comprises the following steps that when the peripheral equipment is connected to the elevator control equipment, the first microprocessor generates a first random number and sends the first random number to the first encryption chip and the peripheral equipment, and the first encryption chip is used for storing a first secret key and a first encryption algorithm; the first encryption chip performs an encryption operation on the first random number by usingthe first encryption algorithm and the first secret key to obtain first ciphertext data, and sends the first ciphertext data to the first microprocessor; and the first microprocessor compares the first ciphertext data received from the first encryption chip with second ciphertext data received from the peripheral equipment, and confirms that the peripheral equipment is legal when the first ciphertext data and the second ciphertext data are identical.

Description

technical field [0001] The present invention relates to the field of electronic technology, and more specifically, relates 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 carry out damage and replacement of accessories, commissioning and maintenance, etc., to ensure the long-term safe use of the elevator. In general, the elevator factory that sells the elevator is responsible for maintenance or its 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, due to the unknown source of accessories, it is difficult to guara...

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
