    摘要: A method for transmitting data between a first and a second point comprises the steps of transmitting data, from the first to the second point, together with a signature comprising bits of a first authentication code, and transmitting an acknowledgement, from the second to the first point. The length of the first authentication code is greater than the length of the signature and the first authentication code comprises hidden authentication bits. The acknowledgement is produced by using hidden authentication bits of a second authentication code presumed to be identical to the first, produced at the second point.
