Short Signatures from DDH Without Pairings or Random Oracles

We present two constructions of short signature schemes based on the polynomial hardness decisional Diffie Hellman. Our simplest scheme guarantees selective security (i.e. the adversary has to commit to the forged message ahead of time) while the second one realizes full fledged existential unforgeability. Remarkably, our schemes can be implemented over standard prime order groups (no pairings needed) and can be proven secure without resorting to the random oracle heuristic.

Porphyrin Self-Assembly in Water: a Versatile Approach to Realize Chiral and Hybrid Materials Based on Melanin-Like Polymers

Over the last decades, chemists have been fascinated in the construction of nanomaterials from small building blocks by self-assembly of porphyrinoids.1 However, these molecules hide manifold trouble; even if the peripheral charged groups make these macrocycles water-soluble, nevertheless, porphyrins remain mainly hydrophobic molecules, preserving the well-known tendency to self-aggregate in aqueous solution. This “dichotomy” is worthy of special attention because (i) it plays a central role ...

Establishment of in vitro regeneration protocols and protoplasts isolation techniques for Sicilian grapevine cultivars

Grapevine is considered a crop of strategic economic importance for both the worldwide extended cultivated area and the high value of wine production industry. Nevertheless, this crop is threatened by several biotic stress, whose management must be addressed in the context of the current climatic crisis where the transition toward a more sustainable viticulture is urgently needed. In this context, the application of new genomic techniques (NGTs) offers a promising approach to improve resistan...

Artificial mental imagery in cognitive robots interaction

Cognitive Robotics is a new and effective approach for the modelling and better understanding of human cognitive functions and to create effective human-robot interaction. This article reviews the recent literature that exploit of the concept of mental imagery as a fundamental cognitive capability to enhance the robot's ability to interact with the physical and social environment. Then, three future interdisciplinary research directions are identified and discussed, highlighting the new colla...
