We use character sums to confirm several recent conjectures of
V. I. Arnold on the uniformity of distribution properties of
a certain dynamical system in a finite field. On the other hand,
we show that some conjectures are wrong. We also analyze several
other conjectures of
V. I. Arnold related to the orbit length of similar dynamical
systems in residue rings and outline possible ways to prove
them. We also show that some of them require
further tuning.

Here, we improve our previous bound on the number of finite fields over which elliptic curves of cryptographic interest with a given embedding degree and small complex multiplication discriminant may exist. We also give some heuristic arguments which lead to a lower bound which in some cases is close to our upper bound.

Recently, multisequences have gained increasing interest for applications in cryptography and quasi-Monte Carlo methods. We study the (generalized) joint linear complexity of a class of nonlinear pseudorandom multisequences introduced by the first two authors as well as the linear complexity of its coordinate sequences. We prove lower bounds which are much stronger than in the case of single sequences since the multidimensional case brings in new and favourable effects.
