Bluetooth Low Energy (BLE) is an international standard protocol widely used in IoT (Internet of Things) environments due to its low power consumption. However, when BLE is used in an Artificial Pancreas System (APS), it faces the threat of Man-In-The-Middle (MITM) attacks. These attacks can lead to eavesdropping on sensitive medical information or manipulation of insulin injection commands, potentially endangering the patient's life. In this paper, we introduce a protocol that mitigates the vulnerability of BLE to MITM attacks and enhances resilience to sudden situations that may occur in APS environments. Finally, we evaluate the implementation suitability by deploying this protocol in a test environment.
