| Abstract. In this paper, an in-depth review will be carried out on general IoT communication protocols and especially Open Charge Point Protocol (OCPP), which is widely used in smart chargers. In this context, the differences between OCPP 1.6 and 2.0 versions in terms of cyber security will be evaluated. We will focus on the concept of OCPP Profile 3, which plays a significant role in the evolution of OCPP, and the effects of the features brought with this profile on system security will be discussed. In order to further strengthen system security, the focus will be on Charge Point Authentication and Central System Authentication systems. How the security of these two endpoints is ensured will be examined. In particular, the measures taken and the certification processes applied to increase the security of Charge Point Authentication and Central System Authentication systems will be explained in detail. In this context, the security measures and standardizations in newer versions of OCPP will be discussed and the integrity and durability of the system will be detailed. A serverless structure will be built with a Central System implemented on Amazon Web Service (AWS). As a result, the advantages and advanced security measures offered by OCPP in terms of cyber security, as well as the measures taken to increase the security of smart chargers, will be examined comprehensively in this study. |
