| Abstract: | By the trace function from the field GF（2） to the subfield GF（2m）, the cryptographic property of a class of nonlinear spreading sequences is considered, that is the trinomial property of the cascaded No sequences. And the trinomial form of the cascaded No sequences is given. Binary No sequences have the same trinomial property from the derived conclusions, trinomial property problem of binary No sequences is solved. Analysis results show that the cascaded No sequences not only have the regular trinomial pairs, but also have regular trinomial pairs. |
