  The Internet of Things paradigm improves the classical information sharing
scheme. However, it has increased the need for granting the security of the
connected systems. In the industrial field, the problem becomes more complex
due to the need of protecting a large attack surface while granting the
availability of the system and the real time response to the presence of
threats. In this contribution, we deal with the injection of tampered data into
the communication channel to affect the physical system. The proposed approach
relies on designing a secure control system by coding the output matrices
according to a secret pattern. This pattern is created by using the Fibonacci
p-sequences, numeric sequence depending on a key. The proposed method is
validated on the Hydra testbed, emulating the industrial control network of a
water distribution system.
