Cryptanalysis of NTRU with two public keys
Abstract
NTRU is a fast public key cryptosystem presented in 1996 by Hoffstein, Pipher and Silverman. It operates in the ring of truncated polynomials. In NTRU, a public key is a polynomial defined by the combination of two private polynomials. In this paper, we consider NTRU with two different public keys defined by different private keys. We present a lattice-based attack to recover the private keys assuming that the public keys share polynomials with a suitable number of common coefficients.
