In the search for trinomial σ -LFSR over finite field $\mathbb{F}_{2^m}$, one type of binary polynomials which are always reducible with an even number of irreducible factors over binary field $\mathbb{F}_2$ were found. We prove this using the Stickelberger-Swan theorem and present one new of special pentanomials over $\mathbb{F}_2$ with the same property.
