Abstract
A method includes generating a first sequence of data words for sending over an interface. A second sequence of signatures is computed and interleaved into the first sequence, so as to produce an interleaved sequence in which each given signature cumulatively signs the data words that are signed by a previous signature in the interleaved sequence and the data words located between the previous signature and the given signature. The interleaved sequence is transmitted over the interface.
