Description:
Registration Authority (RA) (also know as a LRA - Local Registration Authority)
Complete Definition:
An RA is an optional PKI entity (separate from the CAs) that does not sign either Digital Certificates or CRLs but has responsibility for recording or verifying some or all of the information (particularly the identities of subjects) needed by a CA to issue certificates and CRLs and to perform other certificate management functions.
A local registration authority (LRA) is an optional part of a public key infrastructure that maintains users' identities from which certification authorities can issue Digital Certificates. A Local Registration Authority (LRA) is the person authorized by their company and the Certificate Authority (CA) to provide certificate lifecycle management. All companies who want to use Identity services or features must have an LRA.
