Abstract
A server establishes a secure session with a client device where a private key used in the handshake is stored in a different server. An encrypted connection is established between the first server and the second server. A message is received from the client device that initiates a procedure to establish the secure session between the client device and the first server. As part of this procedure, the first server transmits over the encrypted connection a request to the second server to use the private key. The first server receives, over the encrypted connection, a response to the request that includes a result of the use of the private key. The first server uses the result during the procedure to establish the secure session.
