Abstract: The Number Theory Research Unit(NTRU) algorithm is a public key cryptosystem based on rings. When compared with other typical encryption algorithms such as RSA and ECC, the NTRU algorithm has obvious advantages in security and speed. This paper analyzes some existing methods which are comparatively mature in attacking the NTRU, and gives a method of choosing parameters for the NTRU, which enhances security under different application circumstances, avoiding blindness in choosing parameters for the NTRU. It achieves the goal of increasing the algorithms speed of NTRU, as well as reducing occupation of system resources.

Key words: Number Theory Research Unit(NTRU) algorithm, choosing parameters, order, security
