Security control device, authority authorization method and electronic tag reading method

Abstract

The invention designs a security control device, an authority authorization method and an electronic tag reading method, which can apply a single reading device to multiple industry fields to realizecompatible reading, thereby reducing the research and operation cost of reading equipment, including a national password security chip. A security control device is saved in the national password security chip. An issuing system is composed of a certificate CERT_SAM, a root certificate CERT_ISSUE of the issuing system of the security control device, a private key SAM_PRIKEY of the security controldevice and an electronic tag access permission list, all of which are stored in the national secret security chip, and the certificate CERT_SAM comprises a serial number SAM_SN of the security control device; the security control device is provided with an interface connected with a main control processing unit and used for sending an access permission authorization file to the security control device through the main control processing unit, and the security control device is further provided with an interface connected with the radio frequency processing unit and used for achieving the specific reading process of an electronic tag.

Description

technical field [0001] The invention relates to the technical field of ultra-high frequency radio frequency identification, in particular to a safety control device, an authority authorization method, and an electronic tag reading method. Background technique [0002] As a key technology in the Internet of Things, passive UHF radio frequency identification technology is being widely used in automatic identification and digital management of vehicles, personnel, and objects due to its high efficiency, safety, and maintenance-free advantages. The long-distance wireless communication process of the UHF radio frequency identification system has broadcast characteristics, and is extremely vulnerable to forgery, replay and other attacks. For the privacy protection and information security problems in the application of radio frequency identification systems, Chinese patent 201410439094.2 "Hidden UHF "Security Authentication Method for Electronic Tag Identification Number" publishe...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the problems in the prior art that a single reading device cannot realize compatible reading of electronic identifications with multiple coding rules, and cannot be expanded and applied to multiple industries, this application designs a security control device and authorization method and electronic Label reading method, which can apply a single reading device to multiple industries to achieve compatible reading, thereby reducing the R&D and operating costs of the reading device
