SOBER is a stream cipher designed specifically for
fast software implementation on embedded microprocessors,
such as mobile phones. Its use is free for non-embedded
applications. 

The original paper about SOBER was presented at the
Australian Conference on Information Security and Privacy
in July, 1998, (ACISP'98) and proceedings were published
by Springer-Verlag in the Lecture Notes in Computer Science
series. The paper here is significantly more detailed, mostly
in the area of security analysis, and details a slightly more
robust version of the algorithm than that in the original
paper (in the light of the security analysis). The original
version of SOBER was broken by having linear key loading and
insufficient diffusion. This version is thought to be secure,
but has been superceded by t8 (below).
