Strong identities are at the heart of Hyperledger Fabric security. Creating, managing, and revoking these identities is critical to the operational security of Hyperledger Fabric-based deployment. The identities are issued by a MSP. As shown in the previous Hyperledger Fabric architecture diagram, one logical MSP is typically associated with one peer. An MSP can issue any appropriate cryptographically signed identities. Hyperledger Fabric ships with a default MSP, (Fabric CA), which issues X.509 certificates to the authenticated entities.
