Nonlinearities on cryptographic shift registers

Nicolae Constantinescu, Oana Ticleanu, Alin Golumbeanu


Symmetric cryptographic keys generation systems with a high complexity needs nonlinear mathematical models. This condition is due to the necessity of increasing the complexity of attack on the cryptographic model. In this regard, the present paper takes on a new approach of constructing these systems, having as a starting point combinations based on solutions at the border of nonlinear equations.
