The ultrahigh-frequency safe label reader-writer module is a matching module which is specialized for ultrahigh-frequency safe labels, and furthermore can be used as a matching module for ultrahigh-frequency universal electronic labels. A specialized ultrahigh-frequency reader-writer integrated chip is adopted, and furthermore a safe SAM module is integrated in the ultrahigh-frequency safe label reader-writer module. Through the safe SAM module, functions of safe algorithm secret key dispersion, bidirectional discriminating authentication, flow encryption communication, etc. on the ultrahigh-frequency safe label are realized. Simultaneously the ultrahigh-frequency safe label reader-writer module supports the functions of universal labels and safe labels, and can realize an initialization function, an issuing function and an application operation function of the ultrahigh-frequency safe label. The ultrahigh-frequency safe label reader-writer module is a modular product and cannot perform application operation as reader-writer equipment on the labels. The ultrahigh-frequency safe label reader-writer module needs to be embedded into handheld equipment or mobile equipment of user. Additionally, the module supports a built-in safe SAM module form and an external safe SAM module form.
Description
Technical field
The utility model belongs to ultrahigh frequency reader-writer field, the particularly operation such as reading and writing of a kind of ultrahigh frequency safety label.
Background technology
Radio-frequency (RF) identification (Radio Frequency Identification, RFID) technology is a kind of contactless information transmission technology of utilizing the wireless signal such as radio frequency, microwave to realize by the electromagnetic coupled (alternating magnetic field and electromagnetic field) in space, and this technology is mainly applied to information identification field.Rfid system is generally made up of read write line, label and antenna, and it utilizes wireless radio frequency mode to realize read write line and label (identification target) carries out data interaction.According to the difference of working frequency range, rfid system can also be divided into three kinds of low frequencies (LF), high frequency (HF), ultrahigh frequency (UHF), ultrahigh frequency RFID recognition technology has the advantages such as operating distance is far away, communication speed is fast, cost is low, size is little, becomes the emphasis of rfid system development in the ban.
Ultrahigh frequency RFID is with its distinctive application feature, developed in the basin such as logistics, storage rapidly, in addition, also had a taste of the characteristic of ultrahigh frequency RFID with the commodity counterfeit prevention application of logistics, storage field close relation, therefore, in recent years, the false proof application demand of ultrahigh frequency RFID logistics emerged rapidly.
Utility model content
The utility model is for the designed supporting read-write application apparatus module of ultrahigh frequency safety label, the available application read write line of realizing ultrahigh frequency safety label, and fundamental purpose is to coordinate the application of ultrahigh frequency safety label and development and Design.At present, ultrahigh frequency safety label is because its working method is all not identical with the general ultrahigh frequency electronic tag of standard with inner structure, the application operating of ultrahigh frequency safety label all needs supporting with it read-write equipment just can carry out, and traditional general ultrahigh frequency electronic tag read-write equipment can not support the use with ultrahigh frequency safety label.
For realizing the object of this utility model, the ultrahigh frequency reader-writer integrated chip that the super high frequency radio frequency front end that requirement is used and agreement are all integrated in one, requires the secure cryptographic algorithm of using, authentication certification and the safety communication flow process of safety label all to be completed by hardware security SAM module.
The utility model comprises main circuit substrate and electro-magnetic shielding cover, and on described main circuit substrate, integrated design has module external interface terminal SOCKET, module main control microprocessor, ultrahigh frequency reader-writer integrated chip, safe SAM module, antennal interface port.Wherein, module external interface terminal SOCKET is placed in respectively with antennal interface terminal two substrate edges that main circuit substrate is relative, and module main control microprocessor, ultrahigh frequency reader-writer integrated chip, safe SAM module are positioned at the central authorities of substrate; Have, be positioned at circuit substrate top as the radome of electromagnetic screen, will all devices external wiring terminal SOCKET and antennal interface terminal be shielded in radome except module, radome is fixed by special shield clip and circuit substrate.
The radome of module is fixed on circuit substrate.
