Block cipher in NTRU

Abstract
In every sector today, secure and efficient data transfer is essential. To guarantee the security, for the most part Public Key Cryptographic Systems (PKCS) is utilized. A RSA and NTRU framework by and large fits in with the class of PKCS. The productivity of an open key cryptographic framework is essentially measured in computational overheads, key size and transmission capacity. The way that most chips on keen cards can't handle keys broadening 1024 piece demonstrates that there is a requirement for option. NTRU [7] is such an option and it is a gathering of numerical calculations in view of controlling arrangement of whole numbers and polynomials. This permits NTRU to be effective. NTRU is the main secure open key cryptosystem not in view of factorization or discrete logarithm issues. This means that given sufficient computational resources and time, an adversary, should not be able to break the key. Basically NTRU cryptosystem encrypt and decrypt a binary message. As mentioned in NTRU[8], it takes p= 3 and q =31 to have a binary message encrypt and decrypt properly. As modulus 3 contains any of the integers 0, 1 or 2, it is not certain to decrypt a binary message properly. So NTRU came with an alternative by taking p = 2+X. In this paper we have attempted to show that it can be extended to hexadecimal system and the speed of sending and receiving can be much faster by using hexadecimal system instead of binary system.
