The encryption chip system is structured that a central processing unit (CPU) in a central processing memory is respectively connected with a calendar clock circuit, a system clock circuit and a read-write memory in an unsealing detection circuit, a CPU and a memory, a read-only memory and a random memory, wherein the unsealing detection circuit provides an unsealing detection signal to the central processing memory; and a data communication interface circuit sends communication data to and receives the same from the central processing memory.
Description
Technical field
The present invention relates to anti-fake encrpted chip, be specially a kind of encryption chip system, be used in the false proof link of circulation of commodities.
Background technology
Existing anti-counterfeiting technology mainly contains: bar code anti-counterfeit, sequence number are false proof, telephone service, laser anti-counterfeit, package anti-counterfeiting, these all are static, illegal person only need duplicate or reclaim its bar code, sequence number, laser mark, packing just can reach the purpose of mixing the spurious with the genuine, and makes real commodity can not get ensureing.It is false proof to utilize the dynamic encryption circuit to carry out, owing to be dynamic information, therefore, safety, good confidentiality, bootlegging hardly may.Smart card, electronic tag all are a kind of data carriers of static state, are replicated easily and usurp.The anti-string goods of commercial articles safety, anti-personation core are ID authentication and behavior supervision, for after commodity load onto the Antiforge electronic label, make the beginning of dispatching from the factory, and can realize the commercial affairs process trace that circulates.Simultaneously, help to improve consumption product supplied safety.The Antiforge electronic label has contactless (RFID) and contact two classes authentication type of attachment, and wherein the contact existence is operatively connected inconvenience, almost uses in the antifalsification label system at present, and still, contact has the simple advantage of interface circuit; Contactless existence need be separated the technical matters that must not be attached to metal and a plurality of label collisions, and prior art solves described problem at present, but the label cost is higher, still, has easy to operate advantage.Middle-grade in a large number, on the low side shelves are worth general goods needs low cost, highly reliable, electronic labelling system easily, communication interface module device low cost, highly reliable be the basis that reduces system cost.
Summary of the invention
The objective of the invention is at above technical matters, a kind of low cost, highly reliable, encryption chip system easily are provided.
Technical scheme of the present invention, specific as follows:
Encryption chip system, by data communication interface circuit, central authorities handle and storer, the calendar clock circuit, the Kaifeng testing circuit, power supply is formed, data communication interface circuit is by the Data Receiving treatment circuit, the data sending processing circuit connects the central processing unit in central authorities' processing and the storer, the contact type data communication interface circuit connects the data receiving processing circuit respectively, the data sending processing circuit, the central processing unit in central authorities' processing and the storer connects the calendar clock circuit respectively, Kaifeng testing circuit and central authorities handle and storer is interior system clock circuit and readable and writable memory, ROM (read-only memory), random access memory.The Kaifeng testing circuit provides the Kaifeng detection signal to central authorities' processing and storer.Data communication interface circuit sends, accepts communication data to central authorities' processing and storer.
Central processing unit (CPU), storer, Kaifeng testing circuit (placing the commodity packaging sealing part), contact processor circuit, power supply.Central processing unit is connected respectively at contact treatment circuit, storer, system clock circuit, calendar clock circuit, Kaifeng testing circuit, and all circuit connect in power supply.Data-interface is connected in the contact treatment circuit, storer comprises ROM (read-only memory) (ROM), random access memory (RAM), readable and writable memory (EEPROM), ROM (read-only memory) is along the deposit operation system software, intermediate data when random access memory is used for central processing unit work is temporary, readable and writable memory is deposited operation result, and anti-counterfeiting information.
Encryption chip is in initialization procedure, also reach with commodity simultaneously in the encapsulation process, at first by the contact data interface circuit in external communication, through the contact treatment circuit data are carried out modulation and receive initialization data, and make in order by centre and to deposit in the readable and writable memory, the testing circuit that breaks a seal simultaneously is in to connect to be opened state and finishes initialization, also reach the encapsulation process of finishing encryption chip and commodity, and the encryption chip initialization information is stored in the computer system data storehouse in the commodity place of production, after finishing initialization, central processing unit writes treatment circuit with automatic permanent shutoff data, the secondary data that prevents encryption chip writes, and the user can pass through dedicated reader reading encrypted data.
In the circulation of commodities process, the consumer can inquire about dynamic anti-fake information by reader.
When the consumer inquires about anti-counterfeiting information with reader, central processing unit accesses the initialization enciphered message in the readable and writable memory and reads simultaneously the calendar clock circuit current time, produce one as function through cryptographic calculation cipher-text information is newly arranged, and be stored in the readable and writable memory again, the cipher-text information that will newly produce through central processing unit transmits and is presented on the LCDs of reader by the contact communication interface again, the consumer uses SMS, modes such as internet send to cipher-text information in the place of production computer system of commodity, the place of production computer system of commodity will be finished consumer's query script according to verifying cipher-text information current effective time (as 10 minutes) and the result being returned on consumer's mobile phone with short message mode.Because the cipher-text information of inquiry is also to be dynamic anti-fake information in relevant age information of current time, to inquire about the period so surpass effectively, it is invalid that the place of production computer system of commodity will be judged.
After commodity were selected the opening use by the consumer, the Kaifeng testing circuit of Antiforge electronic mark writing paper was in off state.Central processing unit is solidificated in all anti-counterfeiting information in the readable and writable memory, no longer carries out any cryptographic calculation, so all anti-counterfeiting information will effectively all cease to be in force automatically after the inquiry period.
