This paper presents a new key management protocol of wireless sensor network based on NTRU public key cryptosystem, which includes node authentication using the NTUR digital signature and showing an implementation process of establishing encryption key between nodes, adding a new node, and eliminating the invalid nodes. This paper also analyzes the security of the protocol, the storage overhead, communication...
The NTRU algorithm is a public key cryptosystem based on rings. When compared to other typical encryption algorithms such as RSA and ECC, the NTRU algorithm has obvious advantages in security and speed. This article 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...
