Abstract
A method includes establishing an application layer transport layer security (ATLS) connection between a network device and a cloud server by sending, from the network device, TLS records in transport protocol (e.g., HTTP) message bodies to the cloud server, the ATLS connection transiting at least one transport layer security (TLS) proxy device, receiving, from the cloud server via the ATLS connection, an identifier for a certificate authority, establishing a connection with the certificate authority associated with the identifier and, in turn, receiving from the certificate authority credentials to access an application service different from the cloud server and the certificate authority, and connecting to the application service using the credentials received from the certificate authority.
