On Software Implementation of Fast DDP-based Ciphers
Data-dependent (DD) permutations (DDP) are discussed as a cryptographic primitive for the design of fast hardware, firmware, and software encryption systems. DDP can be performed...

Optimal Vibratory Stick-Slip Transport
Abstract--We describe a vibratory part transport mechanism that utilizes both static and dynamic friction to linearly transport parts in a horizontal direction. We derive a horizon...
