Summary: In 1991, Chang and Wu proposed a cryptosystem for broadcasting messages in computer networks based on the characteristics of the Interpolating polynomials and some properties of the Euclidean geometry. We show that their scheme is not secure enough because the secrete points of the users can be derived by an opponent.
