Abstract

The embodiment of the invention relates to a data protection method for an NFC (Near Field Communication) tag. The method comprises the following steps: presetting a first transmission key, a second transmission key and first signature data; identifying an instruction code of the received instruction; when the instruction code is a data key loading instruction, first date data and a first key plaintext are extracted; generating a first date type; selecting a current transmission key from the first transmission key and the second transmission key according to the first date type; dispersing the first key plaintext according to the current transmission key and the first signature data to generate a first key ciphertext and a second key ciphertext; storing the data key group; when the instruction code is a data writing instruction, extracting a first data plaintext; performing data encryption storage on the first data plaintext according to the data key group; when the instruction code is a data reading instruction, obtaining a second data ciphertext; and performing plaintext analysis on the second data ciphertext according to the data key group to generate and return a second data plaintext. Through the method, the risk of user data leakage caused by a plaintext storage mode can be avoided.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a data protection method of an NFC tag. Background technique [0002] In the tobacco industry, the application of NFC tags based on the principle of Near Field Communication (NFC) to anti-counterfeit traceability of cigarette cartons can increase the difficulty of imitation of counterfeit goods. However, in existing NFC tag implementation schemes, plaintext storage is often used to manage data in the user data storage area, which will undoubtedly bring a certain risk of data leakage. Contents of the invention [0003] The purpose of the present invention is to provide a data protection method for NFC tags, electronic equipment and computer-readable storage media for the defects of the prior art, using a protection key pair based on the Advanced Encryption Standard (Advanced Encryption Standard, AES) algorithm The data in the user data storage area is protected by ciphe...
