Description
Technical field
The present invention relates to a kind of Anti-fake electronic label, specifically, what relate to is a kind of electronic tag anti-counterfeiting authentication method, belongs to electronic label technology field and field of information security technology.
Background technology
Mifare series contactless IC card is the classical IC card product of NXP company.It mainly is included in gate inhibition and campus, public transport field widely used Mifare1 S50(1K byte), S70 (4K byte), and simplify version Mifare Light and upgrade version MifarePro4 kind chip model.In these several chips; except Mifare Pro, all belong to logic encryption card; namely inside does not have independently CPU and operating system; rely on the built in hardware logical circuit to realize the IC-card of safety certification and protection fully; what it adopted is the ISO14443A international protocol; need by read write line and the triple key authentications of electronic tag during on-the-spot read-write operation, password is set in advance, and is relatively open to supporting read write line.Mifare series contactless IC card range of application is covering the whole world.Only this card of domestic distribution estimates at several hundred million and is coming into operation, and its fail safe relates to numerous units of operation and holder's interests.
The researchers German and U.S. in 2009 have successfully cracked the security algorithm of the Mifare1 chip of NXP, the researcher is by the communication data between research read write line and the card, find the cryptographic algorithm of this class card and the agreement of authentication communication, and had two kinds of methods can obtain the subregion password of MIFARE class logic encryption card.By this method, the saboteur can use the equipment that is dirt cheap just can obtain easily the password of a M1 card within the extremely short time (40ms).
After M1 card safety problem exposes, some companies avow and know about the way of determining, magic weapon wherein is exactly so-called " card one is close ", namely the key of each sector of each card is not identical, use SIM card Load System root key, unique sequence number UID according to the M1 card calculates sub-key, prevents that a card is cracked and affects whole system.The M1 cartoon is crossed the SAM card and is realized that " card one is close " is the sub-key that obtains the M1 card after the master key in the SAM card is disperseed by the card number to the M1 card in essence, finishes authentication to the M1 card but this sub-key still will expressly send the card reader base station ic to by the terminal single-chip microcomputer.What more seriously the SAM card was sent is M1 cardamonin literary composition password, and the hacker just can obtain by it the password of all cards as long as obtain a SAM card, and the means that crack all need not.Read write line or background application system are many with the unique sequence number UID of electronic tag to the authentication of on-the-spot electronic tag, and the one-way hash function computing (Hash computing) that namely comprises the application message data of UID produces identification identifying code or Protective Key.
Because the universalness of chip design production firm, copy to write as the UID of unique sequence number and be one and easily accomplish thing.In addition, in the situation that M1 card consumption password is revealed, even adopted online method of supplementing with money, also can't ensure the interests of operator, because in the case, the thief uses the M1 card of forgery, fully can be without the password of supplementing with money of system, and directly adopt the default password (full F) of M1 card that card is carried out " supplementing with money ", then consume in terminal with real consumption password.In the case, even adopted blacklist mechanism also to be difficult to avoid operator and to award the card vendor family suffer a loss, because blacklist mechanism is a kind of afterwards Avoid, what prevent is the transaction that same pseudo-card occurs again, and consume today of day by day popularizing at the M1 card small amount, the thief only needs the puppet card is used once, just is enough to obtain than a much higher income of pseudo-card cost.Therefore, existing Mifare class series noncontact logic card antifalsification is relatively poor.
CPU card and M1 logic encryption card are diverse two kinds of cards, and their authentication mechanism is fully different.The CPU card is because inside has the internal memory of CPU processor and operating system COS and super large, and the process of authentication is carried out between subscriber card and SAM card fully, and what transmit in the verification process is random number and ciphertext, and the card reader base station ic is a communication channel; Verification process is reproducible not; The algorithm that uses is public algorithm, and its fail safe is based on the CPU card to the protection of key but not to the protection of algorithm.Key all can not be read in subscriber card and SAM card, and the installation of key is to be undertaken by ciphertext, even hair fastener personnel and developer also can't obtain key plain after the online implementing, has fundamentally guaranteed Security of the system.
But simultaneously, the CPU card is compared with the logic encryption card system, and the system of CPU card seems more complicated, need to carry out the more system reform, such as key management, transaction flow, PSAM card and card personalization etc.If meet the CPU bank card of the PBOC2.0 of People's Bank of China finance standard, such contactless CPU calorie requirement carries out on-the-spot static data authentication (card antifalsification authentication), and the critical data that read-write terminal uses public-key in technology (rivest, shamir, adelman RSA, ECC and Hash scheduling algorithm combination application technique) the checking card is not changed behind hair fastener.Need to super many energy (generally being that noncontact logic encryption card tens is to hundreds of times) during such CPU Ka Nei system computing, mean that needs consume more exchange hour and requirement is read and write at harsher scene.The system complexity of CPU card is high, systemic openness is low, non-contact transaction speed is slow, transaction-based requirements are high, and CPU card chip area, chip cost and use cost are also than the high decades of times of non-contact logic encryption card, therefore application surface has been subject to very large restriction, particularly uses under the soft tag environment of noncontact and hardly may.Non-contact logic encryption card has very large superiority condition than the CPU jig, be chip area little-unsuitable cracked, cost is low-and chip and read-write Verification System cost are low, read-write convenience-exchange hour is short and success rate is high, good environmental adaptability-antistatic is anti-pollution anti-wear, is beneficial to especially market and popularizes.
Therefore, the Anti-fake electronic label that the present invention mentions is for general low-cost Non-contact radio-frequency electronic tag, such as the M1 non-contact logic encryption card.The present invention carries out the system reforms such as Digital Logic, internal memory, power supply to current M1 noncontact logic card, overcomes its weakness, strengthens its anti-counterfeit capability, and satisfying the market needs.
