Embodiment 1

[0044] figure 1 It is a flow chart of realizing the authentication method of the electronic cigarette pod shown in the second embodiment. The authentication method for electronic cigarette cartridges shown in Embodiment 1 is applicable to electronic cigarette cartridges, for example, placed in the MCU of the electronic cigarette stick. For ease of description, only the parts related to the embodiments of the present invention are shown, and the details are as follows:

[0045] Step S110, obtaining the random number sent by the electronic cigarette pod.

[0046] Step S120, using the random number to scramble the current plaintext to obtain a first scrambled plaintext.

[0047] Step S130, using the RC4 algorithm to encrypt the first scrambled plaintext to obtain first MAC data.

[0048] Step S140, comparing the first MAC data with the second MAC data sent by the electronic cigarette cartridge to determine whether the electronic cigarette cartridge is authenticated.

Abstract

The invention is applicable to the technical field of electronic cigarette cartridge authentication, and provides an electronic cigarette cartridge authentication method and device and an electronic cigarette. The electronic cigarette cartridge authentication method comprises the following steps: acquiring a random number sent by an electronic cigarette cartridge; scrambling the current plaintextby adopting the random number to obtain a first scrambled plaintext; performing encryption processing on the first scrambling plaintext by using an RC4 algorithm to obtain first MAC data; and comparing the first MAC data with second MAC data sent by the electronic cigarette cartridge, and determining whether the electronic cigarette cartridge passes authentication or not. Due to the fact that theRC4 algorithm low in hardware resource consumption is adopted, the technical problem that an electronic cigarette cartridge authentication method is high in cost is effectively solved, the plaintext is scrambled through the random number, and the authentication safety is effectively improved.

Description

technical field [0001] The invention belongs to the technical field of authentication of electronic cigarette cartridges, and in particular relates to an authentication method and device for electronic cigarette cartridges. Background technique [0002] With the development of technology, the experience of electronic cigarettes is far superior to that of traditional cigarettes, which makes the electronic cigarette market huge. Most of the e-cigarette pods on the market do not have the function of anti-copying boards, so there are a large number of counterfeit e-cigarette pods on the market, which not only damages the interests of design companies, but also counterfeit e-cigarette pods may also be harmful to consumers’ physical and mental health. cause some damages. [0003] At this stage, there are many anti-counterfeiting means, such as security chips, special anti-copy board chips, and small-capacity EEPROMs. The security chip is a dedicated MCU that has passed security ...
