An algorithm to obtain an RSA modulus with a large private key

L. Hernández Encinas and J. Muñoz Masqué and A. Queiruga Dios

Abstract: Sufficient conditions are obtained on the prime factors of an RSA modulus in order to avoid Wiener and Boneh-Durfee attacks. The public exponent can be chosen arbitrarily.
