Extended Linear Cryptanalysis and Extended Piling-up Lemma

In this paper, we extend the idea of piling-up lemma and linear cryptanalysis applied to symmetric-key block ciphers. We also examine this new method of Extended Linear Cryptanalysis on two-round Rijndael, which is designed to be immune to linear cryptanalysis attack. Even though our results do not show much surprise on two-round Rijndael, the effects on other block ciphers remain open questions.

Vehicle Routing for a Complex Waste Collection Problem

We consider a complex waste collection problem, where the residents of a certain region dispose of recyclable waste, which is collected using a fixed heterogeneous fleet of vehicles with different volume and weight capacities, fixed costs, unit distance running costs and hourly driver wage rates. Each tour starts and ends at one of several depots, not necessarily the same, and is a sequence of ...

Piling Up Pillar[5]arenes To Self-Assemble Nanotubes.

New liquid-crystalline pillar[5]arene derivatives have been prepared by grafting first-generation Percec-type poly(benzylether) dendrons onto the macrocyclic scaffold. The molecules adopt a disc-shaped structure perfectly suited for self-organization into a columnar liquid-crystalline phase. In this way, the pillar[5]arene cores are piled up, thus forming a nanotubular wire encased within a she...
