Abstract
Approaches are disclosed for switching transport protocol connection keys. In a transport protocol module configured to use a first key for signing messages associated with a transport protocol connection, a second key is configured for the transport protocol connection. A first message that is associated with the transport protocol connection is received. The first message includes a first signature. A first and a second message digests are computed for the first message, where the first message digest is based on the first key and the second message digest is based on the second key. The first message is validated if the first signature in the first message matches any one of the first message digest and the second message digest.
