I have no clue whether the stream cipher in that paper is any good,
but the security analysis in the paper is basically nonsense.
The paper contains gibberish like "[axiom] A8 comes true by a relativistic
interpretation". Your guess is as good as mine what that is supposed
to mean. And the alleged "proof" of Theorem 1 is bogus. In general, the
paper mimics the language of provable security, but without the content.
I would not recommend using a cipher that has not been published in an
appropriate peer-reviewed conference and scrutinized by the cryptography
community for several years. Based on this, I would not recommend using
this stream cipher at this time.
