Secrecy Capacity of Diffusive Molecular Communication Under Different Deployments

Currently, the physical layer security is considered as one of most suitable techniques in Diffusive Molecular Communication (DMC) because ease to implement. A recent piece literature has presented Secrecy Capacity (SC) DMC system under rectangular deployment. To evaluate information capacity (IC) and thereby SC using Concentration Greens Function (CGF) molecular communication depends on biological structures tissues. In this paper, we have investigated analytical expressions IC both Biological Cylindrical Deployment (BCD) Spherical (BSD). Therefore, been employed derive mathematical BCD BSD environment. Further, analyzed a function distance/radius considering power and/or bandwidth parameter. addition, effect distance authentic receiver also explored. It observed that irrespective deployments, illustrates predominant value SC. The proposed analysis useful implementation different tissues structures. numerically simulated results show close agreement with theoretical background.
