In this paper, we propose a new stream cipher construction based on block cipher design principles. The main idea is to replace the building blocks used in block ciphers by equivalent stream cipher components. In order to illustrate this approach, we construct a very simple synchronous stream cipher which provides a lot of flexibility for hardware implementations, and seems to have a number of desirable cryptographic properties.
