When compared to their temperate coastal counterparts, sediments deposited and preserved along arid aeolian shallow-marine margins remain relatively poorly understood, particularly at the scale of lithofacies units architectural elements.

We present the first rigorous specifications and provably-secure implementation, for a communication layer providing time-stamped evidences for the message delivery process. This improves on existing standards for evidences (‘non-repudiation’) services,...
