Radio frequency label data protection method of safe storage structure having multi-stage protection

Abstract

Disclosed are a radio-frequency tag and a method for a safety storage structure with multi-level protection; the data storage structure of the radio-frequency tag comprises a key area, an authority control area and a storage block; the storage block is divided into a public data area and a private data area; the radio-frequency tag has an exclusive serial number and generates an exclusive root key, so that one tag has one key; the data in the tag is processed with signature authentication to realize multi-level protection of the data. The tag and the method described by the invention have theadvantages that the serial number is exclusive and the generated root key is also exclusive, so that one tag has one key to greatly increase the difficulty in breaking through the tag and improve thesecurity performance of the tags; for different applications, only the root key needs to be replaced to achieve compatibility so as to greatly simplify the key management difficulty, without losing the security performance of the tags.

Description

technical field [0001] The invention relates to a storage structure of a radio frequency tag, in particular to a radio frequency tag with a secure storage structure with multi-level protection, which uses radio communication as a transmission medium and has transmission encryption and access authority control, and a method thereof. [0002] Background technique [0003] High-frequency electronic tags are currently the most widely used radio-frequency tag products. Traditional radio-frequency tags simply encrypt the data in the communication process, but do not encrypt or protect the data stored inside the tag, which makes the access key safe. Management becomes more complicated and cautious. Once the access key is lost in a certain link, it will cause great harm to the entire system. [0004] Contents of the invention [0005] The technical problem of the present invention is to provide a radio frequency tag and a method thereof with a secure storage structure with multi-...
