The Certificate Management Protocol (CMP) [RFC4210] requires a well-
defined transfer mechanism to enable End Entities (EEs), Registration

PKIMessage sequences between them.
The first version of the CMP specification [RFC2510] included a brief
description of a simple transfer protocol layer on top of TCP. Its
features were simple transfer-level error handling and a mechanism to
poll for outstanding PKI messages. Additionally, it was mentioned
that PKI messages could also be conveyed using file-, E-mail-, and
