NTRU: A Ring-Based Public Key Cryptosystem

We describe NTRU, a new public key cryptosystem. NTRU features reasonably short, easily created keys, high speed, and low memory requirements. NTRU encryption and decryption use a mixing system suggested by polynomial algebra combined with a clustering principle based on elementary probability theory. The security of the NTRU cryptosystem comes from the interaction of the polynomial mixing syst...

MaTRU: A New NTRU-Based Cryptosystem

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−1), whereas NTRU oper...

SMS Security Using NTRU Cryptosystem for M-Commerce

Short Message Service (SMS) is getting more popular now-a-days. SMS was first used in December 1992, when Neil Papworth, a 22-year-old test engineer used a personal computer to send the text message "Merry Christmas" via the Vodafone GSM network to the phone of Richard Jarvis in the UK. It will play a very important role in the future business areas of mobile commerce (M-Commerce). Presently ma...
