The Linear Orthomorphisms on the Ring Zn
Yazhou Xiong, Haiqing Han, Siru Zhu · Research Journal of Applied Sciences Engineering and Technology · 2013
Linear orthomorphism has the well diffusibility, which can be used to design P-permutation in cryptography. This paper presents the definition of the linear orthomorphisms and orthomorphic matrices on the integer residue class ring, whose counting formulas have been obtained too. They have provided a theoretical basis to research the nature of orthomorphisms on the ring in the cryptography.
