Further improving security of Vector Stream Cipher

Atsushi Iwasaki, Ken Umeno

Vector Stream Cipher (VSC) is a stream cipher which consists of permutation polynomial over a ring of modulo $2^{w}$ . The algorithm for generating key stream is very simple and the e…

One-stroke polynomials over a ring of modulo $2^{w}$

Atsushi Iwasaki, Ken Umeno

Permutation polynomials over a ring of modulo $2^{w}$ are compatible with digital computers and digital signal processors, and so they are in particular expected to be useful for cry…

Three Theorems on odd degree Chebyshev polynomials and more generalized permutation polynomials over a ring of module $2^{w}$

Atsushi Iwasaki, Ken Umeno

Odd degree Chebyshev polynomials over a ring of modulo $2^{w}$ have two kinds of period. One is an "orbital period". Odd degree Chebyshev polynomials are bijection over the ring. The…
