The importance of security in software and hardware components becomes the major concern nowadays. This paper focuses on adaptive component-based control systems following the reconfiguration architecture analysis and design language (denoted by RA2DL). Despite of its efficiency, RA2DL component can be compromised due to its lack in terms of security. This paper proposes a new method for modeling the security of RA2DL component, argues for a more comprehensive treatment of an important security aspect with several mechanisms such as authentication and access control. In this paper, we propose a new architecture of RA2DL where pools are containers of sets of RA2DL components characterized by similar properties. The proposed approach is applied to a real case study dealing with Body-Monitoring System (BMS).
