    摘要: Approaches are disclosed for switching transport protocol connection keys. A method of automatically changing a message authentication key at each of two endpoints of a connection in a telecommunications network comprises testing a date-time value received in each of a plurality of data segments on the connection; and selecting a next message authentication key, from among a plurality of stored message authentication keys, for use in authenticating subsequently received data segments, when the date-time value matches a specified characteristic.

    摘要: 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.

    摘要: 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.
