Electronic lock of slot machine and method for unlocking electronic lock

Abstract

The invention provides an electronic lock of a slot machine and a method for unlocking the electronic lock. The electronic lock of the slot machine comprises a microprocessor module, a central processing unit (CPU) card key reader, a contactless CPU card key, a driving module, an electromagnetic lock core which is arranged at a door of the slot machine, and a power control module. The method for unlocking the electronic lock comprises the following steps that: the microprocessor module reads a unlocking secret key and unlocking time, which are pre-stored in the contactless CPU card key, through the CPU card key reader; when the unlocking secret key and the unlocking time accord with unlocking conditions, the microprocessor module generates an unlocking control signal, and subtracts one time from the unlocking time which is pre-stored in the contactless CPU card key; and the microprocessor module controls the locking and unlocking operation of an electromagnetic lock core according to the unlocking control signal. According to the electronic lock of the slot machine, the defects that a contactless integrated circuit (IC) card in the prior art is low in security and easy to crack are overcome.

Description

technical field [0001] The invention relates to an electronic lock, in particular to an electronic lock for a slot machine and an unlocking method thereof. Background technique [0002] Bus coin machines generally use DALLAS single-bus buttons as the key to unlock electronic locks. With the development of technology, the safety of coin machines using this unlocking method can no longer be fully guaranteed, and the loss of bus fares is becoming more and more serious. Having attention. At present, there are non-contact IC cards on the market as unlocking keys for coin machines, hereinafter referred to as electronic keys, but most of the electronic keys are realized by M1 cards. Although this type of card has better confidentiality, it still cannot be 100% secure. It is safe and has been cracked at present. [0003] The CPU card uses the internationally recognized 3DES algorithm with high confidentiality. At present, there is no technical means to crack the DES encryption alg...

AI Technical Summary

Problems solved by technology

[0002] Bus coin machines generally use DALLAS single-bus buttons as the key to unlock electronic locks. With the development of technology, the safety of coin machines using this unlocking method can no longer be fully guaranteed, and the loss of bus fares is becoming more and more serious. Having attention

At present, there are non-contact IC cards on the market as unlocking keys for coin machines, hereinafter referred to as electronic keys, but most of the electronic keys are realized by M1 cards. Although this type of card has better confidentiality, it still cannot be 100% secure. safe, and has been cracked

[0003] The CPU card uses the internationally recognized 3DES algorithm with high confidentiality. At present, there is no technical means to crack the DES encryption algorithm. Using it as an electronic lock key has high security recognized by the industry, and the COS system in the CPU card is Customized system, no consistency, high key security
