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.
