Abstract : Nowadays, different types of electronic data transfer are supported by applications due to the expansion of Internet. These applications may run on desktop machines (PCs, servers, etc.) or mobile devices (PDAs, smartphones, etc.). A prerequisite and a critical issue for these transfers is the assurance of security properties. HTTPS, based on SSL/TLS, offers these properties but SSL/TLS is high-energy consuming and the properties are provided as a block. This has an important impact on the battery life of mobile devices and thus, solutions are needed. In this paper, we propose a security management architecture, based on adaptable security components, externalizing security functionalities from mobile devices. Our security management architecture is a first step towards an effective and energy efficient management of distributed systems.
