ABSTRACT: NTRU is a lattice-based public key cryptosystem
featuring reasonably short, easily created keys, high speed, and low memory
requirements, seems viable for wireless network. This paper presents two
optimized designs based on the enhanced NTRU algorithm. One is a light-weight
and fast NTRU core, it performs encryption only. This work has a gate-count of 1175
gates and a power consumption of 1.51 μW. It can finish the whole encryption
process in 1498 μs at 500 kHz. As such, it is perfect for wireless sensor
network. Another high-speed NTRU core is capable of both encryption and
decryption, with delays of 16,064 μs and 128,010 μs in encryption and
decryption respectively. Moreover, it consists of 25,758 equivalent gates and
has a total power consumption of 59.2 μW (it will be reduced greatly if low
power methods were adopted). This core is recommended to be used in base
stations or servers in wireless network.
