Research on a lightweight security communication method based on OTP and OTK

Abstract

In recent years, as a product of the new era, the Internet of Things technology has become more and more widely used in various aspects such as intelligent transportation, logistics management, and electronic tags. With the rapid development of Internet of Things technology, there are also many problems. In view of the current characteristics of the Internet of Things (IoT): the terminal devices are of uneven size, the storage and processing capabilities are inconsistent, and the connections are intermittent. In order to anti these characteristics, we come up with a low energy consumption, low computational communication project which doesn’t need the third party and has the relatively high security. The project comprises an identity authentication scheme based on OTP (One Time-Password) and a key agreement scheme based on OTK (One Time-Key). This project can achieve the desired authentication and secure communication proved by the theoretical analysis, it doesn’t have any security defect and has good security and credibility.
