摘要：
The invention relates to a method of generating a pseudorandom string of terms belonging to a finite body K of cardinal q≧2 intended to be used in a cryptography procedure, said method comprising the iterative calculation of a system (Γ) of m polynomials with n variables belonging to the finite body K. According to the invention, the coefficients of these m polynomials are regenerated at each iteration. The invention also relates to pseudorandom string generator intended to implement this method.
