The invention discloses a consumable authentication chip and an encryption authentication method, and relates to the technical field of encryption authentication, and the consumable authentication chip comprises an information tracing unit which is used for storing static information and dynamic information of a consumable in an encryption form, and a secret key and an authentication protocol; the static information comprises factory information, a life cycle initial value, a unique identification code, a material number, manufacturer information, a production date, a backup identification code and a serial number; the dynamic information comprises charging times and a health degree state; the anti-counterfeiting authentication unit is used for generating authentication information by adopting a hash function based on the stored information so as to carry out authenticity verification on the equipment; the service life management unit is internally provided with a counter, manages the service life of the consumable according to the number of times of charging, can trigger state change when a preset threshold value is reached, and achieves the service life of the consumable by constructing a three-party authentication architecture composed of a consumable authentication chip, using equipment and a cloud server and combining a physically isolated secret key storage and dynamic change authentication mechanism. And high-security consumable identity authentication and full-life-cycle management are realized.

This invention discloses a rapid visual identification method and kit for the vintage of buckwheat liquor based on a dual-channel colorimetric reaction. Addressing the issue of counterfeit vintage in buckwheat liquor, it sets up two independent detection channels: the first channel uses a solid-phase extraction column with a mixture of polyamide and uncapped C18 filler or uncapped C18 filler to remove flavonoid interference, controlling the sample flow rate through the column at 0.8~1.2 mL / min, and uses a p-toluenesulfonic acid-p-dimethylaminobenzaldehyde solid colorimetric strip to detect the aging year of the base liquor for 2~5 minutes; the second channel uses ferric chloride-potassium ferricyanide colorimetric paper to detect the aging time based on the negative correlation between reducing substances and bottle storage time. The dual-dimensional results comprehensively determine the authenticity of the vintage label. This invention is safe to operate, provides intuitive results, and offers strong anti-counterfeiting features with dual verification, making it suitable for various scenarios such as consumer self-inspection, liquor company quality control, and market supervision.
