Abstract: This report explicitly refutes the analysis behind a recent claim that NTRUEncrypt has a bit security of at most 74 bits. We also sum up some existing literature on NTRU and lattices, in order to help explain what should and what should not be classed as an improved attack against the hard problem underlying NTRUEncrypt. We also show a connection between Schnorr's RSR technique and exhaustively searching the NTRU lattice.
