Approaches are disclosed for switching transport protocol connection keys. A first node sends a keychange request message to a second node, causing the second node to accept subsequent messages digitally signed with a first or second key. The second node sends an acknowledgment message to the first node, causing the first node to accept subsequent messages digitally signed with the first or second key. The first node receives a new message digitally signed with the second key from the second node and determines that there are no remaining messages to be received digitally signed with the first key. In response thereto, the first node only accepts messages digitally signed with the second key and sends a message signed with the second key to the second node, causing the second node to only accept messages digitally signed with the second key.
