Description

Navigation material flow data block chain, sharing system and tracing method
Technical Field
The invention belongs to the field of airworthiness management of civil aviation parts, and relates to an airworthiness material flow data block chain, a sharing system and a tracing method.
Background
The operation of civil aviation involves the use of a large number of aviation materials, and whether the aviation materials are qualified is an important influencing factor for entering the civil aviation operation. "acceptable aircraft" simply refers to aviation components and equipment approved or approved by the civil aviation agency, including "three attributes": the first is legitimacy, i.e. the compliance with regulations regarding airworthiness in civil aviation regulations should be indicated by a complete and effective certification document; secondly, ensuring that the navigability condition is effectively maintained during storage and transportation; third is traceability, i.e. the used airlines should have time and cycle of use, time and cycle of use after renovation, and historical data confirming their historical status.
Therefore, management of the electronic airworthiness approval certificate of the airwaves and tracing of the historical data are always main working contents of the airlines, airports and supply chain managers thereof. However, the traditional navigation material tracing mode has the problems of asymmetric information, complicated examination and approval, easy data tampering and the like, so that the second-hand navigation material is difficult to commonly apply in the industry, and the method also becomes one of the main influencing factors of high domestic civil aviation operation cost. When the operation of the China civil aviation is restored, how to reduce the operation cost and efficiently utilize resources becomes one of important concerns of various aviation companies in China. Therefore, the use of "second-hand navigation materials" and the effectiveness of the "second-hand navigation materials" in the navigation material field and the retrospective management have become the focus of heat.
Aiming at the problem that the aviation operator in China uses the second-hand aviation material, the China civil aviation office revises and exports 3 related files in order to further standardize the safety, traceability and systematic management in the process of selling and using the aviation material, and the method is used for guiding the aviation operator in China to safely, reasonably, normally and effectively use the second-hand aviation material. It is explicitly proposed in the relevant document that: the qualified second-hand navigation material needs to be provided with a navigable approval label/a navigable approval certificate, and the related certificate is a traceability file which can be effectively, so that the traceability of the navigation material is achieved to be' in mind; blockchains are actively applied to the content of the second-hand navigation material airworthiness management and the like.
Although the civil aviation office in China already permits the use of the airworthiness histories in the form of electronic data, the present airworthiness approval label/certificate (hereinafter referred to as "electronic airworthiness approval certificate") original paper and a large number of history records (such as maintenance records, replacement records and the like) are mainly relied on in the airworthiness management to realize the tracing and judging whether the airworthiness is qualified, reliable and airworthiness, so that the following four problems are caused:
1. the data sources are not reliable enough: the history of the aircraft needs to include information such as the use, repair, and maintenance. However, such data is often collected from multiple suppliers and operators using different types of systems and operating specifications. Therefore, there may be problems of inconsistent data formats, data loss, or errors.
2. Information sharing is difficult: sharing of the aircraft history data is very difficult due to the data exchange involved between the organizations. Different data formats, security protocols, access rights, etc. may exist between different service providers, operators, and regulatory authorities.
3. Privacy protection problem: since the avionics biographical data may contain sensitive commercial information and customer privacy, appropriate measures need to be taken to protect privacy while sharing and exchanging. This also increases the difficulty of data sharing.
4. The supervision is insufficient: current regulatory authorities have relatively weak regulatory forces on the second-hand aerospace market, resulting in quality and compliance problems in the market. More sophisticated regulations and standards are required to ensure the quality and safety of the aircraft materials.

In this embodiment, the avionics circulation data sharing system further includes an avionics circulation data verification module configured to determine, according to the uploaded avionics verification information, whether the avionics circulation data is consistent with the avionics circulation data on the blockchain.
In this embodiment, the navigation material streaming data sharing system further includes an entity tag, and generates navigable data according to the unique number TID of the entity tag and the electronic navigable approval certificate of the navigation material, so as to realize association between the entity tag and the block data.
The aircraft related units to which this embodiment relates include aircraft manufacturers (OEMs), aircraft dealers, aircraft operators, maintenance units (MROs), and dismantling facilities, and are not inventive as they are shown in the figures with dashed boxes.
(1) In the whole life cycle circulation process of the aviation material, the aviation material related units generate related data, such as OEM data, distribution data, use data, maintenance data, scrapped data and the like, according to the practical application of the aviation material, maintenance, scrapped and the like. Meanwhile, in the OEM and MRO links, it is necessary to reissue an electronic airworthiness approval certificate (electronic airworthiness approval certificate), and thus the generated data also includes airworthiness data.
According to the related requirements of the civil aviation bureau of China, the electronic airworthiness approval certificates issued by the two are consistent in the whole field structure, but the electronic airworthiness approval certificate issued by the OEM can be used as the demonstration of airworthiness or compliance, and the electronic airworthiness approval certificate issued by the MRO can only be used as the demonstration of airworthiness. Meanwhile, OEMs typically issue new pieces and MROs issue repair pieces.
(2) And the related data are subjected to standardized model conversion and data desensitization by a corresponding circulation data uplink module according to the data model requirement applicable to the retrospective management of the avionic material electronic airworthiness approval certificate, and are sent to the corresponding uplink module.
(3) In the circulation data uplink module, the uplink certification of the data is completed according to a block chain data block structure which is suitable for the traceability management of the aviation material electronic airworthiness approval certificate.
(4) In the process of the navigation material circulation, after the navigation material related units receive the navigation material, the data verification module can finish the tracing and verification of the navigation material resume data, so that the authenticity, reliability and credibility of the navigation material information are ensured. Meanwhile, when the data text corresponding to the desensitization data is required to be read in the related verification, the exchange of the navigation material resume data text can be realized through the navigation material resume data trusted exchange module.
Referring to fig. 3, the present invention further provides a method for tracing the navigation material circulation data based on the navigation material circulation data sharing system, wherein the navigation material circulation data verification module in the navigation material circulation data sharing system uploads any one of verification information including a navigation material part number, a navigation material serial number and a unique number TID of an entity tag to verify the navigation material.
(1) After the manufacturer produces the aviation material, the manufacturer issues an electronic airworthiness approval certificate. For the readability of the electronic airworthiness approval certificate, the issued electronic airworthiness approval certificate generally adopts a PDF format. The PDF format electronic airworthiness approval certificate can be effectively traced to the main body, airmaterials and behavior data, wherein:
Ent(str)＝Sign (i )(EID)
ent (str) is used for forming main body identification data in the block main body, if the block data is uploaded by the ith alliance unit in the block chain, then Ent (str) uses the ith encryption private key for the unit, and the unique unit number EID of the unit is subjected to signature value after signature operation. By using the public key in the alliance, the subject information corresponding to the entity key can be determined, so that the accurate recognition of the subject is realized.
A subject refers to an aerospace material circulation-related unit including, but not limited to, an aerospace material manufacturer (OEM), an aerospace material dealer, an aircraft operator, a maintenance unit.
Equ(str)＝Oid(PN+SN)
Equ (str) is used for forming the navigation material identification data in the block main body, and generally, symmetric encryption and decryption algorithms Oid commonly agreed by the block chain alliance are used for symmetrically encrypting and decrypting the part number and serial number of a specific navigation material, so that accurate identification of the navigation material in the block information is realized.
Beh(str))＝type_id
Beh (str) is used to construct behavior identification data in the block body, typically by commonly agreed behavioral dictionary table numbers of the blockchain alliance, such as P for manufacturing, M for maintenance, R for repair (including refitting), O for repair, S for sales, and A for scrapping.
Lub 1 (str)-Hush(Pdf Sm2 )
Lab 1 (str) data for indexing the electronic airworthiness approval certificate among tag data Lab (str) in the block body, which is extracted and hashed from the electronic airworthiness approval certificate signed by the SM2 algorithm.
(2) After issuing the electronic airworthiness wholesale certificate, the manufacturer can be associated with an entity tag (such as an RFID tag and an IC card tag) and the like, so that the flow direction of the airworthiness material can be accurately known in the circulation process of the airworthiness material entity, and the fact that only a user with the entity tag can trace the unqualified public data is ensured. Meanwhile, the production record data in the production process of the aviation material can be desensitized and then displayed on the chain. Wherein,
Lab 2 (str)＝TID
Lab 2 (str) data for indexing the entity tag in the navigable data Lab (str) constituting the block body, the unique number TID of the entity tag can be generally used directly because of the uniqueness of the entity tag number and the non-directly resolvable specificity.
Lab(str)＝Str(Lab 1 (str)+Lab 2 (str))
Lab (str) is used to construct navigable data in the block body, which is obtained in step (1) and step (2) 1 (str) and Lab 2 (str) in combination.
Rec(str)＝Hash(Doc)
Rec (str) is used for forming the history data in the block main body, the specific history data is obtained by the data storage main body through hash calculation after being packed according to actual conditions, and the unique history data or history data packet can be traced back, so that the verification of the history of the navigation material is further supported.
The part number, serial number and number of the airworthiness label of the airworthiness material can be used as the airworthiness material verification information. But only trace legal public data, only possess entity label (entity label is valid) can trace to source non legal public data, because every time the maintenance of aviation material can replace entity label, last time aviation material outflow object and current person's identity of tracing under the condition, can write in this time's resume data, realize the data uplink.
(3) According to the flow direction of the aviation materials, the three flow directions of installation use, maintenance and inventory/sales can be divided, and the three flow directions correspond to the roles of an operator, an MRO and a dealer respectively. However, no matter the specific flow direction, the electronic airworthiness approval certificate and the resume data corresponding to the airworthiness material are required to be traced and verified after the airworthiness material is received, so that the origin of the airworthiness material is real and the resume is reliable. The electronic airworthiness approval certificate and the historical data are traced and verified in detail as shown in fig. 4.
(3.1) obtaining the TID by scanning the space material entity tag.
(3.2) reading PN and SN of the entity part, and calculating on-chain navigation material identification data Equ (str) =old (PN+SN)).
And (3.3) traversing the block chain to obtain all block information consistent with the navigation material identification data.

Calculated here is a hash that traces back the electronic navigable approval certificate in the human hand.
And (3.6) comparing whether the subject information and the behavior information in the electronic airworthiness approval certificate are consistent with the analysis result of the blockchain certification, and if so, keeping true.
The entity tag is only one of channels for tracing the proving material and the opening data of the aviation material, and a new entity tag can be issued again along with the maintenance of the aviation material. All the navigation material circulation data are stored on the blockchain, the entity tag only provides unique coding TID, and the navigation material circulation data are not stored, because the entity RFID tag can store 2K data at most under the state of the art, and has extremely high cost and no practicability.
The invention can directly trace back all electronic record original data of the aviation material owned by the data owner, not only solidifies ownership and authenticity of the electronic record of the data, but also trace back corresponding original data on the premise of guaranteeing the ownership of the data, thereby realizing the credible and controllable transaction of the original data.
And (3.7) when the original data is required to be queried, the block address is required to be sent to a block chain intelligent contract service, such as contract permission to retrieve the original data, and a data request is sent to the corresponding block main system.
And (3.8) after the corresponding main body receives the request and returns the original data of the history record to the blockchain, calculating hash of the history data or the history data packet, and comparing Rec (str), if so, returning the original data of the history to the data requesting party, thus finishing the data trusted exchange.
(4) For operators, the uplink certification of the data related to the navigation material use history needs to be completed in the navigation material use process. The timing of the certification should cover at least the aircraft loader and the aircraft removal, and in order to ensure the integrity of the aircraft tracing, at least the following data should be used for uplink:
numbering the aviation material loading machine;
time of installation;
the disassembly time;
the loading machine is used for hours;
the machine uses a cycle.
When the aviation material is detached, if the aviation material does not need to flow out, the installation and the use are continued and the step is completed continuously. And if the aviation materials flow out, entering a maintenance, sales or scrapping link according to the actual flow direction.
(5) For MRO, after the maintenance of the aircraft material, the uplink storage of the maintenance history related data is required to be completed according to the maintenance condition of the aircraft material, and in order to ensure the integrity of the tracking of the aircraft material, at least the following data should be used for uplink:
a maintenance mode;
maintenance records;
maintaining and releasing records;
and (5) replacing and recording parts.
(6) After maintenance release, a new electronic airworthiness approval certificate needs to be issued synchronously and is associated with the entity tag. The association and the uplink process can be completed by referring to the step (2).
(7) For the aviation material distributor, the uplink certification of the sales history related data is required to be completed according to the aviation material sales condition in the aviation material sales process, and at least the following data should be used for uplink in order to ensure the integrity of aviation material tracing:
