Device Protocol Design for Security on Internet of Things based Smart Home

Trio Adiono, Bryan Tandiawan, Syifaul Fuada


One of the major challenges that arise in the internet of things (IoT) based smart home systems is security issue. It is still relatively low in which the exchange of data between devices can easily be stolen by outsiders since it is connected to the internet. In this work, we present the details of the protocol messages in smart home appliances that are encrypted by RSA algorithm and AES in which the RSA key was regenerated in every turnover of the day (exactly at 00:00:00 or 1 x 24 hours) since the last key generation by mobile. The performance test is done by sending an error command and a correct command to the RGB lamp device. The results show that the designed protocol works well as expected. Given the security mechanism in the designed protocol, data exchange between devices in the smart home will be hard to break by outsiders. Thus, the users can enjoy their smart home privacy without worrying the intruders (hacker).
