Abstract
The IoT (Internet of Things) environment develops in which all the necessary information among things is exchanged due to the development of information and communications. The home IoT continuously develops, because of a merit that a user can control the home IoT remotely in the IoT environment. As the home IoT environment is built, communications using low specification devices, as well as high specifications devices, also increase. For safety communications in the home IoT environment, encryption algorithms, such as RSA providing message encryption and authorization, are required. However, they are difficult to be used for the low specification devices, where calculation function is limited in the home IoT environment. This study actually proposes the protocol by which low power and low specification devices communicate with user’s smart devices through safe authorization procedure in the home IoT environment. The protocol proposed in this paper has a merit that it is safe, and it protects the re-use attack and middle attack.
