immutability, integrity, and transparency of the product origin for the multi-actor processes of enterprises This thesis will study the open-source Blockchain (DLT) platforms and propose a suitable solution (permissioned blockchain) to implement the demo for a novel process flow of the product origin traceability for the food brand Vissan After conducting the comparison of the Blockchain (DLT) platforms, focusing on the permissioned ones, Hyperledger Fabric is selected, and further discussed regarding its performance, technical architecture, ledger, network, peer, ordering service, consensus, smart contract development, and the market adoption applying Fabric into the different business domains The demo is implemented to indicate the Fabric capability as an enterprise-grade and production-ready permissioned blockchain platform to solve the addressed problem of the product origin traceability The observation of security aspects is presented as an inclusive view of the application using Fabric Blockchain (DLT) The scope of the thesis includes, briefly: 1) Studying the general permissioned Blockchain (DLT) platforms, consensus algorithms, and select the final DLT after the empirical comparison 2) Studying the architecture and technical design of Hyperledger Fabric 3) Conducting a typical process related to the value chain of a food brand (Vissan) going through from the production (manufacturing stage) to the stage that products are at stores (selling stage) and building the demo using Fabric to prove the security, integrity, transparency, and immutability of the data recorded in the blockchain system A public explorer view (to show the latest status blocks, network, chaincodes, view blocks, and transactions) is also provided to visualize the ledger

Luan an Do an vi counterfeit management system for Vissan’s products This thesis implements the system demo after studying the foundation knowledge and thoroughly comparing the blockchain platforms The proposed system demo (at minimum viable product level) of the typical process with multi-actors involvement proves that the Blockchain (DLT) is a good solution for the product traceability for the company value chain The manufacturer (production side) and seller (customer side) transactions are recorded in the Fabric blockchain network so that the stakeholders could easily trace the anti-counterfeiting of the purchased branded Vissan products throughout the blockchain platform With this implementation which ensures the security and immutability of the data in the value chain of the company, the third-party arbitration mechanism such as regulators can also be used to check the illegal part of the value chain easily whenever any incidents happen to the given products So, inclusively, this helps adequate protection for the Vissan food brand, as a whole from production parties to end customers of Vissan The study elaborates the Fabric technical architecture design and analyzes the blockchain enablement indicating that the proposed system has a better implementation comparing to other traditional ways of implementation for the product origin traceability for the multi-actors process of the private company With the smart contract (chaincode) execution in the blockchain network, to some extent, Vissan’s demo system is difficult to forge by malicious attackers The identity verification of all product status updates at each step in the value chain (from manufacturer to sellers) is designed to stop counterfeit substitution by illegal parties for the production or sale process Furthermore, end customers are later easily checking and analyzing the authenticity of Vissan’s product and facilitate querying the data in the Blockchain (DLT)

security risk analysis model to review the application This model analyzes information insecurity risks, including Spoofing identity (authentication ậ impersonating something or someone else), Tampering with data (integrity ậ modifying data or code), Repudiation (claiming to have not acted), Information Disclosure (confidentiality - exposing information to someone not authorized to see it), Denial of Service (availability ậ deny or degrade service to users), and Elevation of privilege (authorization - gain capabilities without proper authorization) With the below analysis and evaluation according to the STRIDE model for the system, we can conclude that the system achieves the desired security requirements 5.3.1.1 Against Spoofing identity Supposedly a situation where the attacker will spoof the certificate authority account to attack this system, because the credential issuer's account is verifiable through the X.509 certificate via the Fabric certificate authority (CA), so this is impossible 5.3.1.2 Against Tampering It is not possible to modify any transaction because it has been included in the ledger thanks to the blockchain design, as the tamper-proof system As Fabric uses the Elliptic Curve Encryption Algorithm (ECDSA) to ensure the security of the entire system, therefore the communication is encrypted in every process in the value chain by ECDSA to ensure the system’s data integrity, non-repudiation, and privacy As we have discussed, Fabric as a permissioned platform enables confidentiality through its channel architecture and private data feature In channels, participants on its network establish a sub-network where every member has visibility to a particular set of transactions Thus, only those nodes that participate in a channel have access to the smart contract (chaincode) and data transacted, preserving the privacy and confidentiality of both Private data allows collections between members on a channel, allowing much of the same protection as channels without the maintenance Stt.010.Mssv.BKD002ac.email.ninhd

corresponding to the public key in the issuer's X.509 certificate All information posted on the blockchain by a CA will always be monitored and tracked back to that identified organization, therefore no participant can impersonate them as analyzed above 5.3.1.4 Against Information Disclosure It is impossible to compute the private keys from the public key used in the Fabric Therefore, there is no risk of exposing private keys from participants as the private keys must be stored in the secret storage 5.3.1.5 Against Denial of Service (DoS) DoS attacks disrupt the network’s availability and are a threat to any distributed system Many different attacks can result in denial of service, which makes it difficult to proactively prevent This risk can be mitigated by collecting performance metrics, such as transaction throughput and latency, to detect compromised availability early on Since the Fabric is deployed as a distributed system (microservice architecture) with multiple nodes deployed not in a centralized environment, therefore the DoS threat is also mitigated compared to other traditional applications 5.3.1.6 Against Elevation of privilege The highest authority in the system is the root organization This right is guaranteed by a digital signature using ECDSA Therefore, it is impossible for attackers can gain authority or fake the digital signature (certificate authority) in

Luan an Do an 87 system demo after studying the foundation knowledge and thoroughly comparing the blockchain platforms The proposed system demo (at minimum viable product level) of the typical process with multi-actors involvement proves that the Blockchain (DLT) is a good solution for the product traceability for the company value chain The manufacturer (production side) and seller (customer side) transactions are recorded in the Fabric blockchain network so that the stakeholders could easily trace the anti-counterfeiting of the purchased branded Vissan products throughout the blockchain platform With this implementation which ensures the security and immutability of the data in the value chain of the company, the third-party arbitration mechanism such as regulators can also be used to check the illegal part of the value chain easily whenever any incidents happen to the given products So, inclusively, this helps adequate protection for the Vissan food brand, as a whole from production parties to end customers of Vissan By comparing with the traditional solutions, this proposed system focuses more on the security protection of data by using the Fabric blockchain The study elaborates the Fabric technical architecture design and analyzes the blockchain enablement indicating that the proposed system has a better implementation of the product origin traceability for the multi-actors process in private companies With the smart contract (chaincode) executed in the blockchain network, and data populated to the ledger, to some extent, Vissan’s demo system is difficult to forge by malicious attackers The identity verification of all product status updates at each step in the value chain (from manufacturer to sellers) is designed to stop counterfeit substitution by illegal parties for the production or sale process Furthermore, end customers are later easily checking and analyzing the authenticity of Vissan’s product and facilitate querying the data in the Blockchain (DLT) And with further recommendations to complete the wider scope significantly, the future implementation can: (a) add and administrate more organizations accordingly to other business aspects such as regulators, financial partners, payment e-wallets, etc Stt.010.Mssv.BKD002ac.email.ninhd
