- W4296461844 abstract "Enterprise blockchain use cases have confidentiality requirements when executing cross-organizational business processes or workflows across their corporate boundaries. For instance, only a certain privileged subset of organizations may know of the workflow's existence and is allowed to access sensitive workflow's data assets such as price information. A private or permissioned blockchain such as Hyperledger Fabric (HLF) provides many features to support those enterprise use cases that require confidentiality. Nevertheless, the blockchain architects need to decide when it comes to how to use them, when to use them, and what are the performance and security implications of those design decisions. This work presents a generic methodology to design a secure Hyperledger Fabric (HLF) blockchain architecture with a given security requirements. To achieve that, we developed and used a novel formal description to specify a generic multilateral workflow in the context of an enterprise use case. Furthermore, the security of the resulting architecture is evaluated against an attacker model and relevant countermeasures are presented. In addition, the performance impact of proposed changes is evaluated using the Hyperledger Caliper benchmarking framework." @default.
