Abstract
A secure Virtual Network Computing (VNC) connection between a server and a client is authenticated using a series of message exchanges. A server receives a request from a client to establish a VNC connection. If the request indicates that the client supports an encryption scheme, the server provides a first set of mechanisms for a subsequent authentication process. If the request indicates that the client does not support the encryption scheme, the server provides the client a second set of mechanisms for the subsequent authentication process. The second set contains fewer mechanisms than the first set. The client chooses an authentication mechanism from the first set or the second set provided by the server. The server and the client then perform the subsequent authentication process, using the authentication mechanism chosen by the client, with a series of message exchanges.
