Abstract

In this paper, we propose a new variant of the NTRU public key cryptosystem - the MaTRU cryptosystem. MaTRU works under the same general principles as the NTRU cryptosystem, except that it operates in a different ring with a different linear transformation for encryption and decryption. In particular, it operates in the ring of k by k matrices of polynomials in R = Z[X]/(X-N - 1), whereas NTRU operates in the ring Z[X]/(X-N - 1). Note that an instance of MaTRU has the same number of bits per message as an instance of NTRU when nk(2) = N. The improved efficiency of the linear transformation in MaTRU leads to respectable speed improvements by a factor of O(k) over NTRU at the cost of a somewhat larger public key.
