Description
Technical field
The invention belongs to the technical fields of communication system, and in particular to a kind of distribution anti-counterfeiting system and its method.
Background technique
The computing system that compartment system is made of multiple process resources interconnected, their controls in whole system
It can cooperate down to execute a common task, it is minimum dependent on the procedure, data concentrated and hardware.It is respectively calculated in distributed system
Machine, each system resource are all distributions so that data during storing and transmitting, be possible to be intercepted, interrupt, distort,
It exposes, usurp, forge.In order to transmit sensitive information or height confidentiality information, system allows for guaranteeing confidentiality.Dividing
In cloth system, safe guarantee is realized by two ways: one is encryption and decryption technique, including to data and is led to
The encrypting and decrypting of letter system；The other is access control.Encryption technology is applied not only to protection communication, is also used for protection and identifies message
And access control.Safety problem in distributed system mainly includes two contents: confidentiality prevents from unlawfully learning number
According to；Integrality prevents from unlawfully modifying data.
Existing anti-counterfeiting system is as follows:
The prior art one, the anti-counterfeiting system based on RFID: mainly by electronic tag, read-write system and server system three
Part forms.Label and read-write system mainly realize efficient information exchange, and read-write system and background system mainly realize system
The functions such as internal exchange of data, data preservation.Whole system relates generally to the processes such as producing and selling and the veritification of product, and
And between each process by label information coding realize interconnect, this just need to be designed according to different demands different modules into
Row is realized.Conceptual design is as follows:
1. module divides: different modules being arranged according to role's difference, including produces and sells and veritifies, and with mark
It signs identification code and carries out information exchange and data identification.
2. encoding scheme: for label design specialized anti-fake code scheme, manufacturer's information and label information common ID are produced
The uniqueness of product provides safety guarantee for product.
3. label produces: Business Information and product information are carried out data encoding by manufacturer, and are added using SM4 algorithm
The region label E PC is written in close processing；It recycles SM2 algorithm to tag ID digital signature, the region User is written into signing messages.
4. safety Design: the RFID bidirectional identification protocol proposed in this paper based on NTRU algorithm is adopted in this agreement
Both sides' identity is authenticated with digital signature scheme, certification is by then executing interaction, and otherwise interaction terminates, and guarantees the legal of both sides' identity
Property.
5. stability Design: each module realizes different function, function-stable and fast response time respectively in system, is realized
Platform also it is more advanced and stablize.
6. agile kernel model: each module has certain adaptability in system, is able to carry out the updates of data, system
It safeguards and perfect, is adapted to various occasion demands.
For the prior art one, disadvantage are as follows:
1, individual event encrypts, and is easy to be intercepted；
2, label and server system calculate power and use identical, calculation power waste；
3, it needs label to realize intelligent, has aggravated the burden of system.
There are mainly two types of the prior arts two, the mode of data encryption: symmetric cryptography and asymmetric encryption, symmetric cryptography pair
The data element bulk encryption of XML document.The data safety of Web Services and user client communication is can not to establish both sides' letter
The relationship of appointing, symmetric cryptography is exactly fabulous selection.The process of encryption and decryption is direct using symmetrically or non-symmetrically algorithm, selection
Key be data object encryption.The implementation of every kind of encryption specification should all have the public collection of prior algorithm, realize interoperability,
Then corresponding protection element is replaced with relevant EncryptedData element；If the data object of encryption is external resource,
Just a new document is created by the inclusion of the EncryptedData root node process to external quoting resource.XML encryption has three
It can encrypted content: entire XML document；One node (XML element)；The value of node.Send and receive the XML data of encryption
Message is as shown in Figure 4.
(1) it is asymmetric right to generate one for reciever, wherein making public key and private key respectively, anyone can take public key to add
Ciphertext data, and only private key being capable of ciphertext data；(2) sender obtains public key and (can obtain from certification authority, for example PKI recognizes
Card center)；(3) sender generates a secret symmetric key；(4) sender's symmetric key encryption XML element；(5) it sends out
The side of sending uses the public key encryption symmetric key of reciever；(6) data of encryption, symmetric key etc. are combined together by sender,
Generate new XML document；(7) XML document of encryption is sent to reciever；(8) reciever takes out the data, symmetrical close of encryption
Key and other information；(9) reciever takes out symmetric key using private key ciphertext data；(10) using symmetric key decryption XML text
The element encrypted in shelves.The decrypting process and ciphering process of XML document are on the contrary, parsing XML user's uses algorithm, parameter and close
Key positions data to be decrypted, implements decryption oprerations.It as a result should be to replace entire EncryptedData element and represent XML piece
The character string of the UTF-8 coding of section.
The shortcomings that prior art two are as follows:
Single node decryption, is easy to be intercepted；
Using quite, calculation power resource uses unreasonable the calculation power of label and server.
