Abstract

The SOBER family ciphers are generally constructed from a linear feedback shift register (LFSR), a non linear filter (NLF) and a form of irregular decimation called stuttering. Our work aims at having a comparative study of the SOBER family of stream ciphers with regard to design philosophies adapted and security aspects.
