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

Abstract. The grid has emerged as a platform that enables to put in place an inter-organizational shared space known as Virtual Organization. The Virtual Organization (VO) encompasses users and resources supplied by the different partners for achieving the VO's creation goal. Though many works offer solutions to manage a VO, the dynamic, on the fly creation of virtual organizations is still a challenge. Dynamic creation of VOs is related to the automated generation of access control policy to trace its boundaries, specify the different partners' rights within it and assure its management during its life time. In this paper, we propose OrBAC (Organization Based Access Control model) to model the Virtual Organization which serves as a corner stone in the VO creation automated process. OrBAC framework specifies the users' access permissions/interdiction to the VO resources, where its administration model AdOrBAC flexibly models the multi-stakeholder administration in the Grid.

Predicting behaviors is particularly important in the field of environmental management because the environment is greatly influenced by human behavior. This paper aims to contribute to the development of an extended theory of planned behavior (TPB) and to gain some insight into the motives for employees' intentions to implement green practices in Algeria as a developing country. Data were collected from the convenience sample of 182 employees in three Algerian cities using a questionnaire survey. The results indicated that attitude toward behavior, subjective norms and environmental knowledge is positively and significantly affect employee's intention to implement green practices. The results also suggested that perceived behavior control had no significant effect. It is expected that the results of this paper can aid policymakers and stakeholders in drafting and implementing sustainable environmental regulations in the workplace.
