Tripathi and Thakur proposed a new variant of NTRU cryptosystem [8] by using the Exclusive-OR operation. They proposed this system under the same general principles as that of the NTRU cryptosystem except the logical operators “Exclusive-OR” with the different bit size for encryption and decryption are used in place of truncated polynomial in NTRU cryptosystem. In this article we discuss some shortcomings of the scheme [8] and argue that the proposed scheme is not practical and secure.
