Abstract
Embodiments for securely exchanging Certificate Authority (CA) certificates inline and bi-directionally to make it easier for client-server transmissions to use certificate-based authentication. The client certificate is transferred securely through encryption with a pre-shared key based on certain parameters, and the server certificate is transferred securely through encryption with a pre-shared key based on the parameters. The process reduces the burden from applications to maintain and save the CA certificate. It also reduces the burden from server to maintain and save the CA certificate of the client so that server can select it to be used during authentication. This helps enable large scale deployments where the server can maintain the CA certificate and send it to client.
