Problems solved by technology

[0005] That is to say, the encryption authentication between the existing electronic cigarette stick and the pod adopts a fixed encryption and decryption algorithm and a fixed key. This method is easy to be cracked by the pod competitors with the help of instruments, and the principle of encryption and decryption is analyzed. Pods with the same encryption authentication can be imitated, so this single fixed encryption method is not safe and reliable, can be cracked, and it is difficult to achieve effective encryption authentication

Embodiment

[0065] In this embodiment, the communication and interaction process between the device of the electronic cigarette and the pod is as follows: image 3 As shown, it is divided into three parts: RESET connection handshake, UID, TM query, and heating wire switch control. The data will be interacted through the Smart-Wire single line, the device is the master device, the pod is the slave device, and the data initiator is the main equipment.

[0066] In this embodiment, the interaction between the device and the pod adopts an encryption mechanism combining fixed key encryption and dynamic key encryption, and the specific implementation is as follows:

[0067] 1. RESET handshake connection

[0068] When the electronic cigarette is inhaled, the device sends a RESET handshake command. At this time, the data will not be CRC checked and encrypted, and the data will be transmitted in plain text format.

[0069] 2. UID, TM query

[0070] After the device and pod RESET are successfully...

Abstract

The invention discloses an electronic cigarette and an encryption and decryption authentication method thereof. The electronic cigarette comprises a cigarette rod which is used for interacting with acigarette cartridge in a mode of combining fixed secret key encryption and dynamic secret key encryption, the smoke cartridge which is used for interacting with the cigarette rod, a control module which is used for supplying power to the smoke cartridge and forming a communication path for authenticating the smoke cartridge, a power supply module which is used for rectifying and filtering the output of the control module to obtain a direct-current voltage required by the operation of the smoke cartridge, and a heating module which is used for generating heat under the control of an electric heating wire heating control signal output by the smoke cartridge.

Description

technical field [0001] The invention relates to the technical field of encryption and decryption security mechanisms of electronic cigarettes, in particular to an electronic cigarette and an encryption and decryption authentication method thereof. Background technique [0002] Electronic cigarette is an electronic product that imitates cigarettes. Its essence is smoke liquid (nicotine) atomizer, which has similar appearance, smoke, taste and feeling to cigarettes. After the liquid turns into steam, it forms inhalable smoke, which gives the smoker the pleasure of puffing. Since the main component of the smoke oil is nicotine, it does not contain tar, suspended particles and carbon monoxide. For some smokers, it can play a role. A certain degree of smoking cessation effect. [0003] Generally, electronic cigarettes are mainly composed of tobacco sticks, atomizers, and cartridges. The internal components of the smoke sticks include PCB boards, rechargeable batteries, and butto...
