Finding the key of symmetric cipher takes computing common zero of polynomials, which de ne ideal and corresponding variety, usually considered over algebraically closed eld. The solution is the point of the variety over prime eld; it is de ned by a sum of the polynomial ideal and the eld ideal that de nes prime eld. Some authors use partitioning of this sum and reducing syzygies of polynomial ...

A relative approach degree method of grey relation projection is presented to deal with multiple attribute making in which the attribute weight is unknown and attribute value is hybrid index. firstly, the normalized method of different type indices and the formula of distance for the same type indices are defined, and a objective weights determination model based on hybrid index type is constru...
