We present a design approach for hardware-oriented self-synchronizing stream ciphers and illustrate it with a concrete design called Moustique. The latter is intended as a research cipher: it proves that the design approach can lead to concrete results and will serve as a target for cryptanalysis where new attacks may lead to improvements in the design approach such as new criteria for the cipher building blocks.
