Public-key cryptography (PKC), widely used to protect communication in the Internet of Things (IoT), is the basis for establishing secured communication channels between multiple parties. The foreseeable breakthrough of quantum computers represents a risk for many PKC ecosystems. Almost all approaches in use today rely on the hardness of factoring large integers or computing (elliptic-curve) discrete...
The NTRU cryptosystem is one of the main alternatives for practical implementations of post-quantum, public-key cryptography. In this work, we analyze the feasibility of employing the NTRU encryption scheme, NTRUEncrypt, in resource constrained devices such as those used for Internet-of-Things endpoints. We present an analysis of NTRUEncrypt's advantages over other cryptosystems for use in such devices...
