Abstract

Molecular communication (MC) is a new communication paradigm where, opposite to radio or optical communication, the information flow is based on the molecules exchange and chemical interactions. Thanks to the high biological compatibility and nano-scale feasibility, MC is a promising communication technology for health applications, from disease detection to drug in-body delivery. Much attention has been paid to MC in the last decade in investigating the fundamentals of information theory applied to biochemical reactions, while considerations on security have been very limited. A closed-form expression of the secrecy capacity of a diffusion-based MC system is provided. This study is of primary importance to understand the security robustness of the MC paradigm. Through information-theoretical physical-layer security tools, numerical results are presented to study the dependence of the secrecy capacity on the average thermodynamic power, the eavesdropper’s distance, the transmit bandwidth, and the receiver radius. A secrecy map is also presented, which shows the secure and unsecure areas around the legitimate transmitter.
