Abstract
Two-way secure channels are provided between two parties to a communication with certification being provided by one party. One method comprises providing, by a first entity that provides a certificate authority, a first signed certificate to a second entity, wherein the first signed certificate is signed by the certificate authority and wherein the second entity generates a first request to sign a second certificate generated by the second entity, wherein the first request is generated by the second entity using a first credential generated by the second entity; receiving, from the second entity, (i) the first request to sign the second certificate, and (ii) the first signed certificate; and providing, in response to the certificate authority verifying the first signed certificate, a second signed certificate, signed by the certificate authority, to the second entity; wherein one or more additional communications between the first entity and the second entity use the two-way channel.
