International audienceNowadays, 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
The number of mobile devices connected to the Internet is rapidly growing, inducing security issues that cannot be prevented by common mechanisms such as HTTPS. Indeed, mobile environments require light algorithms that can reduce the power-consumption and extend battery life. Moreover, HTTPS does not offer fine-grained control over the security properties such as integrity, confidentiality or authenticity. This lack of flexibility can be problematic for both power-consumption and security robustness. To overcome these issues, we have proposed in previous works a modular architecture, called LECCSAM, based on security components to secure any communication protocol by adding the required security properties. In the context of HTTP, it provides an alternative version of HTTPS by adding the integrity, confidentiality, and authenticity properties to HTTP separately or in block (i.e. only one property or any combinations of two or more properties), depending on the user needs and usage context. In this paper, we propose to extend this alternative version of HTTPS with the non-repudiation property. Preliminary results of the performance evaluation are encouraging.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations鈥揷itations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
