(mentor) Degree granting institution Delft University of Technology Programme Computer Science and Engineering Project CSE3000 Research Project Date 2022-01-27 Abstract Blockchain networks have acquired ongoing notoriety among associations that need to utilise the security perspectives that blockchain gives. Hyperledger Fabric (HF) is one of the most widely utilised distributed network technologies, most ordinarily applied in situations that require private information to be maintained safely and secretly. Usecase models are finance, commerce and healthcare record-keeping.HF has been shown to have vulnerabilities that might allow hostile attackers to gain access to the data contained in the ledger or the state database, according to many studies. Using Shamir’s Secret Sharing (SSS), this paper provides a way to increase the security measurements of information stored on the ledger or in the state database. As a result of this research, design details for implementing these privacy-protection measures are given.In conclusion, although this design improves the security of HF, it also affects the runtime and code complexity.
