Abstract
A message authentication code, for a message transmitted and received over a communications network, is formed by applying inputs to an integrity algorithm acting on the message. The inputs comprise: an integrity key; a value indicating a transfer direction; and a frame-dependent integrity input, wherein the frame-dependent integrity input is a frame-dependent modulo count value that also depends on a random value and on a frame-specific sequence number.
