Secret key issuing system and device of safe RFID electronic label application system

Abstract

The invention discloses a secret key issuing device of a safe RFID electronic label application system. The issuing device comprises a root key and an application secret key generating module, a rootkey card of a root key storage unit, a main discriminating secret key card of an application secret key storage unit, an RFID reader-writer module, an antenna unit, a power management module and a USBcommunication module; the root key and an application secret key generating module comprises a contact type intelligent card read-write control unit and a standard intelligent card seat; the root keycard of the root key storage unit and the main discriminating secret key card of the application secret key storage unit include financial master cards integrated with domestic safety algorithms; thereader-writer module provides a PSAM unit in RF communication with a safe RFID electronic label and integrated with domestic safety algorithms; and the antenna unit serves as an RF coupling channel of an RFID electronic label, and is connected with a host of the issuing device via a 50-ohm RF connecting feed line and an SMA terminal. The issuing device is safe and convenient, and suitable for secret key issuing and management of a middle and small scale safe RFID application and issuing of the safe RFID label.

Description

technical field [0001] The invention belongs to the field of radio frequency identification (Radio Frequency Identification, referred to as RFID) label application and distribution field and the field of security and anti-counterfeiting application technology. Specifically, it relates to a method and a device for generating and distributing relevant application keys in a security application system of a security RFID electronic label, and writing a security RFID identification password. Background technique [0002] Radio frequency identification technology is a non-contact automatic identification technology that began to emerge in the 1990s. It automatically identifies the target object and obtains relevant data through radio frequency signals. The identification work does not require manual intervention and can work in various harsh environments. RFID technology can identify moving objects and identify multiple tags at the same time, which is fast and convenient to opera...

AI Technical Summary

Problems solved by technology

However, the traditional RFID tag issuing equipment cannot realize the functions of security-related key generation, distribution management, etc., and it is impossible to complete the write initialization operation of the security data of the security RFID label including the authentication key.

[0007] Since most customers and system integrators based on traditional general-purpose RFID applications lack experience in security algorithms and key management, the promotion and sales of secure RFID applications have been affected to a certain extent; in addition, if the application performance of secure RFID is evaluated separately in the early stage , the investment in supporting cipher machines and secret management systems is not small, and customers also have certain concerns or give up the attempt and evaluation of secure RFID
