Nowadays, increasing emphasis is placed on efficient and reliable communication in industrial environments. This thesis addresses the technology of Single Pair Ethernet (SPE), which offers a modern and cost-effective approach to data communication using a single pair of wires. Initially, SPE standards were examined and compared with both historical and current Ethernet standards. Furthermore, this thesis focuses on the security risks associated with SPE and methods for their mitigation. As a result, a program was developed that not only facilitates communication using the LAN8651 PHY module but also can simulate cyber attacks such as packet sniffing and packet spoofing, and subsequently secure the communication using the DTLS protocol.
