The FBG Stream Cipher
Said E. El‐Khamy, Mona Lotfy, Adel Hamdi Ali · 2007
In this paper we propose a new synchronous stream cipher; the FBG stream cipher. This cipher is based on FBG (fuzzy bit generator) PN bit generator. The FBG cipher has been designed to produce keystream with guaranteed randomness properties; i.e. passing all the 16 tests of the NIST statistical test suite. Also, it gave very good results when tested using the ENT randomness test program. In addition, it has good correlation properties. The FBG stream cipher is on the form of a non-linear feedback shift register.
