An Electromagnetic Side-Channel-Based Security Level Detection Measurement Approach in Content Transfer Remote Mechanisms

Data confidentiality is a very crucial aspect of modern information society in several fields, and particularly critical in case of telemedicine monitoring. Intrusion attempts represent a very serious threat to deal with. Attacks' success strictly depends on the possibility to get relevant information and manage them. Security mechanisms, including secure communication protocols, make the success probability lower. Unfortunately, several times communication protocols lack strong security protections. Assessing security level can be performed at various levels: in this paper, we prove how it is possible to detect if the information flowing is protected by adopting a simple measurement set-up, exploiting the electromagnetic emissions of the communication device to assess the security level of the undergoing information transfer. It can be seen as a side-channel approach, whose purpose is dual: i) prove how electromagnetic side-channel is a very sensitive part and several pieces of information could be retrieved
