The full-period properties of the sequences generated by the novel map are studied completely. We prove some theorems including full-period judgement theorem on Z(p^n) and validate them by some numerical experiments. In the experiments, full-period sequences are generated by a full-period map on Z(p^n). By the binarization, full-period sequences are transformed into binary sequences. Then, we test the binary sequences with the NIST SP 800-22 software package and make the poker test. The passing rates of the statistical tests are high in NIST test and the sequences pass the poker test. So the randomness and statistic characteristics of the binary sequences are good. The analysis and experiments show that these full-period maps can be applied in the pseudo-random number generation(PRNG), cryptography, spread spectrum communications and so on.展开更多

For a sequence a over Z/(p^e), there is a unique p-adic decomposition a- = a-0 +a-1 .p +… + a-e-l .p^e-1 where each a-i can be regarded as a sequence over Z/(p), 0 ≤ i ≤ e - 1. Let f(x) be a primitive polynomial over Z/(p^e) and G'(f(x),p^e) the set of all primitive sequences generated by f(x) over Z/(p^e). For μ(x) ∈ Z/(p)[x] with deg(μ(x)) ≥ 2 and gad(1 + deg(μ(x)),p- 1) = 1, setφe-1 (x0, x1,… , xe-1) = xe-1. [μ(xe-2) + ηe-3(x0, X1,…, xe-3)] + ηe-2(x0, X1,…, xe-2) which is a function of e variables over Z/(p). Then the compressing mapφe-1 : G'(f(x),p^e) → (Z/(p))^∞ ,a-→φe-1(a-0,a-1, … ,a-e-1) is injective. That is, for a-,b-∈ G'(f(x),p^e), a- = b- if and only if φe-1 (a-0,a-1, … ,a-e-1) = φe-1(b-0, b-1,… ,b-e-1). As for the case of e = 2, similar result is also given. Furthermore, if functions φe-1 and ψe-1 over Z/(p) are both of the above form and satisfy φe-1(a-0,a-1,…,a-e-1)=ψe-1(b-0, b-1,… ,b-e-1) for a-,b-∈G'(f(x),p^e), the relations between a- and b-, φe-1 and ψe-1 are discussed展开更多
