Summary of the invention
The present invention proposes a kind of safety electronic label of innovation, wish to solve electronic tag by bootlegging and by the problem of wrong authentication, especially in, how to guarantee the security of authentication and the particular importance that can not copying property becomes such as applied environments such as E-Passport and e-passport authentication system, state secret facility Personnel Authentication Identification Systems.
For achieving the above object, the technical solution adopted for the present invention to solve the technical problems is:
Electronic tag is custom-designed safety electronic label (Secure RFID), can be operated under two kinds of logic states, be unregistered duty and registered duty, the duty of two kinds of logics is to repel mutually, just when electronic tag was operated in unregistered duty logic, registered duty logic quit work; When electronic tag was operated in registered duty logic, unregistered duty logic quit work.After electronic tag is registered duty logic from unregistered duty logic transition simultaneously, for safety, it is irreversible can setting this logic state, can only be registered duty logic promptly, but can not be unregistered duty logic from registered duty logic transition from unregistered duty logic transition.Safety electronic label (Secure RFID) is different from ordinary electronic label part and also is, under unregistered duty logic working state, the unique identification information of safety electronic label (Secure RFID) is to be made of electronic tag address information and one group of random number, each access security electronic tag, random number all can regenerate, therefore the unregistered safety electronic label of each visit, the random number in the resulting unique identification information partly changes; And under registered duty logic working state, the random number part of safety electronic label (SecureRFID) is locked as encrypted secret key, generate a random number by the authentication management server in the authentication subsystem, add that by the electronic tag address information this random number constitutes the authentication instruction and sends to safety electronic label then, safety electronic label obtains encrypted result data as the random number of encryption key through cryptographic calculation with the random number received and safety electronic label storage inside, safety electronic label is sent these encrypted result data back in the authentication subsystem authentication management server with the electronic tag address information then, compare the cryptographic calculation results of authentication management server and the checkout result of safety electronic label by the authentication management server in the authentication subsystem, if it is identical, authentication success, otherwise authentification failure.Cryptographic algorithm adopts symmetric encipherment algorithm usually, as the DES algorithm.
System is a kind of safety electronic label Verification System with the pairing RFID authentication registration of the present invention, the process software that comprises registration subsystem system, authentication subsystem, database storing equipment and carry out safety certification.In this system, electronic tag among the present invention has only could be by the authentication of authentication subsystem by registration subsystem system registration electronic tag later, and after in a single day electronic tag succeed in registration, its work-based logic will be forced to switch to registered duty, and irreversiblely go back to unregistered duty.When the electronic tag of imitated same label address is registered, owing to there has been the electronic tag address of this address to exist in the registration subsystem system, can find immediately that this electronic tag is to forge electronic tag, registration can be not successful; Simultaneously because electronic tag is supported cryptographic algorithm; and key generates when registering at random at the registration subsystem system; and be stored in database storing equipment and electronic tag inside; the direct access hardware circuit that is stored in safety electronic label internal key data simultaneously when registration the fuse failure in the fuse protected circuit wherein and irrecoverable forever, thereby guarantee that key information can not come out by the data-interface leakage of information of electronic tag.Because the general database memory device all has stronger information processing capability, can encrypt for key data, and be placed in the foolproof environment, can guarantee the information security of key data.
When electronic tag is operated in authentication logic, the identification number of authentication subsystem elder generation electron gain label, the key information of search electronic tag from database, generate a random number R and then, with the key information and the random number process cryptographic algorithm generation operation result Ral of the identification number that obtains, electronic tag.Authentication subsystem sends to electronic tag with Rand, and electronic tag is calculated through same encryption and generated operation result Ral ', sends it back authentication subsystem.Authentication subsystem is Ral and Ral ' relatively, if identical, authentication success then, otherwise can not authenticate.
The design of safety electronic label is divided into two kinds, and a kind of is the passive electronic label that extracts power supply energy from radiofrequency signal, and another kind is the active electronic label that carries supplying cell.
According to above-mentioned design philosophy, the circuit design of passive safety electronic label of the present invention is described as follows:
1. one kind can prevent by the safety electronic label of bootlegging, it is characterized in that a kind of custom-designed safety electronic label, can work in two kinds of duties: unregistered duty and registered duty, at least comprise following logical circuit: aerial coupling circuit, signal transmitting and receiving circuit and instruction analysis logical circuit, power circuit, safety fuse fusing logical circuit, random number occurrence logic circuit, electronic tag home address memory circuit, the cryptographic algorithm logical circuit, receive the data storage logic circuit, the data selection logic circuit, the data output logic circuit, wherein the output of aerial coupling circuit signal is connected with power circuit with signal transmitting and receiving circuit and instruction analysis logical circuit, signal transmitting and receiving circuit and instruction analysis logical circuit and safety fuse fusing logical circuit, receive the data storage logic circuit, the data selection logic circuit, the data output logic circuit all has electrical connection, random number occurrence logic circuit and electronic tag home address memory circuit, the cryptographic algorithm logical circuit connects, electronic tag home address memory circuit is electrically connected with the data selection logic circuit, and the data selection logic circuit is electrically connected with the data output logic circuit; In random number occurrence logic circuit, comprise the key memory circuit that constitutes by the non-volatile memory body.
2. safety fuse fusing logical circuit is arranged between random number occurrence logic circuit and signal transmitting and receiving circuit and instruction analysis logical circuit, safety fuse fusing logical circuit is arranged between random number occurrence logic circuit and data selection logic circuit.
3. safety fuse fusing logical circuit is under unregistered duty, and the fuse in the safety fuse fusing logical circuit keeps connected state, and under registered duty, the fuse in the safety fuse fusing logical circuit is fused.
4. the variation of two of safety electronic label kinds of duties is unidirectional, promptly can only be changed to registered duty from unregistered duty, and can not be changed to unregistered duty from registered duty.
5. the cryptographic algorithm that adopted of cryptographic algorithm logical circuit can adopt symmetric encipherment algorithm.
6. the enough random number occurrence logic circuit of logical circuit energy under the unregistered duty generate random number and store in the key memory circuit as the key information that changes at any time before unregistered, and fused fuse in the safety fuse fusing logical circuit of the logical circuit under the registered duty, the key information of the random number that produced at that time with locking storage during as authentication.
The circuit design of active safety electronic label of the present invention is to increase battery and feed circuit thereof on passive safety electronic label basis, removes from the power circuit of radio frequency induction voltage and current.
The invention has the beneficial effects as follows: because the safety electronic label that is adopted is by custom-designed, its key data that is used for cryptographic algorithm only just is determined after the accreditation verification carrying out, can guarantee the dynamic generation and the safety of key information, and electronic tag is designed to the work-based logic of unregistered state and the work-based logic under the registered state, unregistered safety electronic label can't guarantee the safety of system by authentication in authentication subsystem.Whole safety electronic label generates random number by authentication subsystem and sends to safety electronic label in carrying out verification process, reads the result through computations then, has avoided the leakage of encryption key in transmission, and is imitated by other people.The safety electronic label of comparing prior art is that tag addresses or information data are transmitted to prevent the technical scheme of leakage of information by encrypting the back, but development along with semiconductor design skill manufacturing technology and reverse engineering technology, copying the electronic tag that has identical tag addresses and cryptographic algorithm is can accomplish fully, therefore can't avoid electronic tag to be replicated, and may illegally be used, bring about great losses for legal electronic tag owner.And adopt safety electronic label of the present invention, and even there is the people can the living electronic tag of bootlegging, if the logic state of duplicating is a unregistered state, owing to had the address of this label in the security certification system, therefore can not be by authentication; If the logic state of duplicating is registered logic state, because the password of former legal safety electronic label generates when registration at random, and in case succeed in registration, this information can outwards not transmit through electronic tag yet, as long as guarantee the database data safety of security certification system, code data just can not leaked, so can't duplicate the password of safety electronic label, therefore the electronic tag of bootlegging also can not pass through authentication, thereby efficiently solves the information security issue that electronic tag is brought by bootlegging.Database data as security certification system is considered to the most secret data usually, as long as there is the safe and secret management system of height to get final product resolution system safety of data problem.
