Abstract: At EUROCRYPT '96 J. Patarin introduced the "Isomorphisms of Polynomials (IP)" problem as a basis of authentication and signature schemes. We describe an attack on the secret key of "IP with one secret" and demonstrate its efficiency through examples with realistic parameter sizes. To prevent our attack, additional restrictions on the suggested parameters should be imposed.
