Pain points

In the IoT era, Machine-to-Machine communication technology is the key to establishing an industrial automation environment through information exchange between various devices such as sensors and gateways. Therefore, maintaining a strong authentication network is the first step for a smart factory infrastructure.

- Replay attack

In the process of verifying that the user is correct, the server system exchanges encrypted data such as electronic signatures between users. In the meantime, a third-party hacker tries to impersonate a legitimate user by copying the data that is in transit on the network and then transmitting it to the server as it is. For example, if an industrial robot that performs a service based on recorded data is subjected to a replay attack, it may not be able to perform normal tasks and may endanger workers nearby.

- Impersonation attack

In a modern factory system, numerous machines are paired and operated for efficient production. An impersonation attack is tricked into being a device connected to each other using a persistent encryption key or a long-term key used when multiple devices are first paired. Since the mutual authentication process is no longer required, the attacker controls the devices as the master.
