A Distributed, Parametric Platform for Constructing Secure SBoxes in Block Cipher Designs

2011
Many of the network security protocols employed today utilize symmetric block ciphers (DES, AES and CAST etc). The majority of the symmetric block ciphers implement the crucial substitution operation using look up tables, called substitution boxes. These structures should be highly nonlinear and have bit dispersal, i.e.

Designing with Parametric CAD: Classification and comparison of construction techniques

2001
This paper gives an overview of the rapid evolution of parametrics, from somewhat slow beginnings in academic labs to mainstream commercial CAD. Although not recognized by the user community, parametric CAD is not a single technique but a set of techniques, each with its own advantages and limitations. Each is supported by different technologies.
