“…Further, value of Cs increases with an increase in Eve distance for a given value of bandwidth. Analysis shows perfect match with theoretical background presented in [18]. However, it is remarkable that for proposed BSE Cs is more than that of [18] for same values of Eve's distance and BW.…”

“…However, it is observed that Cs is equal to zero when the distance of Eve is less than the distance of Bob or when Eve's radius is almost equal to the Bob's radius. It is worthy to mention that for the same set of parameters proposed Cs under BSE outperforms over that of [18]. Proposed model will be useful for developing future technologies based on DMC and its practical applications.…”

“…It is noticeable that security in MC is a crucial issue due to presence of eavesdroppers in the network. As per our best knowledge, authors in [18] for the first time propose the secrecy capacity of MC system. However, in this paper we have extended the secrecy analysis presented in [18] by considering a DMC system under Biological Spherical Environment (BSE).…”

Expressions for capacity is However, contrast to [18] Concentration Green's function (CGF) of diffusion under BSE [11], follow asymmetry in all three dimensions, is used to present the secrecy analysis. Interestingly, the reciprocity property of CGF is also considered, i.e., interchanging the location of transmitter and receiver does not change the information channel.…”

Smart drug delivery systems, automation of biological and chemical attacks are the most extensive applications of Diffusive Molecular Communication (DMC). Further, security in DMC is a crucial issue due to presence of eavesdroppers in the network. Recently, Physical-layer Security (PhySec) is regarded as the most suitable security technique as it is easy to implement. On the other hand, Biological Spherical Environment (BSE) is most appropriate for the modelling of spherical tissues such as stomach, lung, kidney and cells. However, none of the literatures have secrecy capacity of DMC under BSE. Therefore, this paper presents expression for Cs of DMC under BSE. In addition, Cs is analyzed as function of Eve's distance and Eve's radius keeping power and/or bandwidth as parameter. Proposed model is useful in analysis of DMC within the spherical tissues. Simulated results show perfect agreement with the theoretical background.
