Increasing empirical research shows a deep connection between timing processes and neural processing of social information. An integrative theoretical framework for prospective studies in humans was recently proposed, linking timing to sociality. A similar framework guiding research in non-human animals is desirable, ideally encompassing as many taxonomic groups and sensory modalities as possible in order to embrace the diversity of social and timing behaviour across species. Here we expand on a previous theoretical account, introducing this debate to animal behaviour. We suggest adopting an evolutionary perspective on social timing in animals: i.e. a comparative approach to probe the link between temporal and social behaviour across a broad range of animal species. This approach should advance our understanding of animal social timing that is, how social behaviour and timing are mutually affected, and possibly of its evolutionary history in our own lineage. We conclude by identifying outstanding questions and testable hypotheses in animal social timing.

In recent years, physical unclonable functions (PUFs) have gained a lot of attention as mechanisms for hardware-rooted device authentication. While the majority of the previously proposed PUFs derive entropy using dedicated circuitry, software PUFs achieve this from existing circuitry in a system. Such software-derived designs are highly desirable for low-power embedded systems as they require no hardware overhead. However, these software PUFs induce considerable processing overheads that hinder their adoption in resource-constrained devices. In this article, we propose DTA-PUF, a novel, software PUF design that exploits the instruction- and data-dependent dynamic timing behaviour of pipelined cores to provide a reliable challenge-response mechanism without requiring any extra hardware. DTA-PUF accepts sequences of instructions as an input challenge and produces an output response based on the manifested timing errors under specific over-clocked settings. To lower the required processing effort, we systematically select instruction sequences that maximise error-rate. The application to a post-layout pipelined floating-point unit, which is implemented in 45 nm process technology, demonstrates the effectiveness and practicability of our PUF design. Finally, DTA-PUF requires up to 50× fewer instructions than existing software processor PUF designs, limiting processing costs and resulting in up to 26% power savings.
