Encryption chip based on hardware random encryption authentication and electronic cigarette comprising chip

Abstract

The invention relates to the technical field of electronic cigarettes, and discloses an encryption chip based on hardware random encryption authentication and an electronic cigarette comprising the chip. An encryption authentication chip comprises a soft encryption and decryption module arranged in a microcontroller and an encryption chip arranged in an atomizer. The soft encryption and decryptionmodule comprises an uplink encryption module, a downlink decryption module and a comparison authentication module, the encryption chip comprises a hardware random transmitter module, an uplink decryption module, a storage module and a downlink encryption module, and the uplink encryption module, the downlink decryption module and the hardware random transmitter module carry out data transmissionthrough single-wire communication. According to the invention, the encryption chip is arranged in the atomizer to carry out hardware authentication anti-counterfeiting identification, and bidirectional random processing is carried out on the ciphertext based on the hardware random emitter in the encryption and decryption process, so that the encryption and decryption process of the chip is more complex, the cracking difficulty is higher, the anti-counterfeiting capability of the encryption chip is improved, and the benefits of merchants and users are effectively protected.

Description

technical field [0001] The invention relates to the technical field of electronic cigarettes, in particular to an encryption chip based on hardware random encryption authentication and an electronic cigarette containing the chip. Background technique [0002] At present, there are mainly three authentication and anti-counterfeiting methods for e-cigarettes on the market: 1) using RFID mode; 2) using the preset anti-counterfeiting code identification mode, and 3) using two-way authentication mode. The anti-counterfeiting methods of the first two methods are relatively simple and easy At the same time, the patent application publication number: CN107114825A announced a chip for controlling electronic cigarettes. Although the chip uses two-way authentication, it directly encrypts and decrypts the original random number. The encryption and decryption process is also relatively Simple, it can be seen that its cracking is also easy to implement. If the electronic cigarette adopts...
