Title:
Key recovery attacks on NTRU without ciphertext validation routine
Authors: Daewan Han, Jin Hong, Jae Woo Han, Daesung Kwon
Abstract:NTRU is an efficient public-key cryptosystem proposed by
Hoffstein, Pipher, and Silverman.
Assuming access to a decryption oracle,
we show ways to recover the private key of NTRU systems
that do not include a ciphertext validating procedure.
The strongest of our methods will employ just a single call to the
oracle, and in all cases, the number of calls needed will be small
enough to be realistic.
