Abstract
A method for protecting encoded data from algebraic manipulation includes receiving a data word sεKto be protected, randomly selecting two integers a ε{0, . . . , q−1} and b ε{0, . . . , √q−1}, finding a point (α, β) on a Hermitian curve over a field Fthat corresponds to the randomly selected integers (a, b) from a mapping (a, b)(α, β)=(u, uz+v), where and z is an element of the field Fof unit trace, and where γis a fixed primitive element of the field Fand γis a primitive element of a field FF, and calculating a sum f(α, β)=αβ+Σαβkfor a set of d+1 integers pairs I ={(i,j)}, where the encoded word is a triple (s, (α, β),f(α, β)).
