Below in conjunction with embodiment and embodiment, the utility model is described in further detail.
As shown in Figure 1, a kind of electronic label safety identification of electronic traffic car plate and the technology of information encryption, include electronic tag, electronic tag includes elbow-board 1, the center of elbow-board 1 is provided with ultrahigh frequency radio frequency identification chip 2, ultrahigh frequency radio frequency identification chip 2 has 860MHz to 960MHz radio frequency operation frequency, is provided with the region of memorys such as information disclosure district, electronic code memory field and User Defined memory field in ultrahigh frequency radio frequency identification chip 2; The both sides of ultrahigh frequency radio frequency identification chip 2 are equipped with label antenna made of aluminum 3, and label antenna 3 receives and launches the radiofrequency signal from read write line equipment, and electronic tag is carried out to authenticity verification; And realization is encrypted, deciphers the information needing protection of ultrahigh frequency radio frequency identification chip 2 interior storages, realization reading and writing encrypted information.
Concrete use step of the present utility model is as follows: more as shown in Figures 1 to 5, when this electronic tag dispatches from the factory, have a unique sequence number in the internal memory in ultrahigh frequency radio frequency identification chip, this sequence number region is information disclosure district, and this region does not arrange password; In ultrahigh frequency radio frequency identification chip, also can be with just like larger capacity region of memorys such as EPC memory field (EPC MEMORY), User Defined memory field (USER MEMORY) simultaneously; be commonly used to storage and need protected user sensitive information; this type of region can be encrypted when dispatching from the factory (or claiming to be locked), therefore by system, is referred to as secret information data area.In use, first to distinguish the not same sex of public information and security information.At label antenna 3 accepting, transmitting be public information time, read write line can directly have access to the open source information district of ultrahigh frequency identification chip 2; When the information that need to access at reception read write line at label antenna 3 is security information, 3 of ultrahigh frequency radio frequency identification chips carry out smart-tag authentication according to received information, to be confirmed whether to allow its access.
The utility model can be realized three kinds of authentication modes, and every kind of mode can be used separately or be combined with other modes.Concrete smart-tag authentication mode is as follows:
Mode one: unique No. TID authentication
As shown in Figure 2, because each ultrahigh frequency electronic tag carries unique disclosed sequence number that dispatches from the factory, i.e. a TID (Tag-ID, or STID,), be locked in the TID memory field of label, so can adopt super intelligent RF (UltraSmart RFID) equipment to verify it.Whether read write line is simultaneously real at this label of checking, also can take the own corresponding mask of sequence number range of client in extra step checking TID internal memory.
Mode two: challenge-response authentication
As shown in Figure 3, IS018000-6C label provides the function that can lock 32 internal memory passwords.This locking page in memory function can be used for guaranteeing that label " knows " authentication password.Read write line can first carry out cryptographic challenge when this shielded region of memory of access, obtains the also response of analyzing tags, confirms whether label knows proper password.This password will transmit with encrypted form all the time in air, and encrypted form adopts this overlay code of the disposal password standard under ISO18000-6C agreement.
The password that each label is used is unique, together with its TID unique with electronic tag, use, by SHA-1 (or SHA-2/SHA-3) Hash (Secure Hash Algorithm), generate a privacy key, this can not expose whole system by the tag pin of guaranteeing to be revealed.
Mode three: packet counting checking
As shown in Figure 4, packet counter, or package flow detection, provide the audit of active data flow backstage, detected cloning function.Only the sub-fraction of the self-defined memory field of tagging user (User Memory) need be used for storing packet counter, UltraSmart read write line is when reading out data package counting facility, will increase progressively once, and when label is put by read-write, the new quantity after increasing progressively be write back to label at every turn.This packet counter, and timestamp and label data, can be transmitted can back-end server.Back-end system just can verify, whether the number of times progress order of reading tag is unified, and to guarantee an only having label to exist, is especially present in a system that has a unique products sign.In packet counter, demonstrate uncontinuity or repeatability, or timestamp is unreasonable, all using the best evidence of forging or cloning as this label system.
Thereby data protection layer has been guaranteed that valuable label information can not be read and has been revealed.Its access mode has selected three kinds:
Mode one: access can be locked memory mechanism
Ultrahigh-frequency tag can adopt 32 passwords to visit can lock secret region of memory, and this function can be used for preventing unauthorized read and write access.Identical with challenge-response label verification method, as shown in Figure 3, this password will transmit with encrypted form all the time in air, and encrypted form adopts this overlay code of the disposal password standard under ISO18000-6C agreement.The password that each electronic tag is used is unique, use by
Unique TID and a privacy key that SHA-1/2/3 Hash (Secure Hash Algorithm) generates, this can not expose whole system by the tag pin of guaranteeing to be revealed.
Mode two: User Defined encoded tag data
The label publisher of operation back-end server (being called for short user) can customize storage data encryption and decryption mechanisms, thereby has unique encrypted feature.Process flow diagram as shown in Figure 4, makes in this way, and label can be only the carrier of an enciphered data and this user will have absolute and unique control to this.
Mode three: key management
System can be recorded in the cipher key index of plain text coded format in User Defined memory block, thus the corresponding specific label of that key of surface.Process flow diagram as shown in Figure 5, when vehicle annual test, can upgrade upgrading to this cipher key index.It should be noted that cipher key index is only encoded recording database, key itself can not be transmitted in space.
Again as shown in Figure 5, system can generate a specific label password, utilizes privacy key and TID in conjunction with reading the data in protected field in label.Will be encrypted when this specific label password being generated by SHA-1/2/3 Hash Secure Hash Algorithm transmits in air.
In actual use, user can, according to self needs, select any one or more than one mode to maintain secrecy to information.
By above mode, the utility model proposes a kind of electronic label safety identification of electronic traffic car plate and the technology of information encryption, by transmitting and receiving of electronic tag radiofrequency signal, make read write line equipment it be authenticated and be obtained enciphered message in label, play and prevent clone, personation label exists, realize user information confidentiality, eliminate the effect of information security risk in label, reach and realize the legal authentication of electronic tag, the object of the continuous healthy and stable development in field such as user information confidentiality and promotion China's intelligent traffic administration system and Parking Area toll administration in label.
