MSPs are in charged for members certificates and authentication. MSP is pluggable, so the default Fabric MSP implementation uses PKI methods and X.509 certificates. You can use commercial CAs or Fabric CA to generate the keys and certificates needed to configure an MSP.

For more information read the Fabric CA documentation and https://hyperledger-fabric.readthedocs.io/en/latest/msp.html

Fabric CA provides features such as: Registration of identities with roles like peer, user or application, or connects to an existing LDAP as the user registry to fetch identities of the mentioned roles.

MSP is a membership service provider defines which certificate authorities(CA's) is allowed to issue certificates.
