Special section:: Security on grids and distributed systems

Some of the papers were presented to provide a suitable overview of topics such as key management, access control, trusted framework and grid systems. Grid and distributed systems provide global sharing of computational resources through high-speed networks, allowing applications to significantly improve their performance. The main challenge of grid computing is the complete integration of heterogeneous computing systems and data resources with the aim of offering a global computing space. Xukai Zou proposed a dual key management (DLKM) mechanism using an innovative concept of an access control polynomial (ACP) and one-way functions. Song Fu and Cheng-Zhong Xu discussed new challenges to resource access control where resource sharing in the grid coalition environment creates temporal and spatial requirements for access by mobile entries. Jinpeng Huai described an implemented CROWN grid and ROST an original scheme of Remote and hOt Service deployment with Trustworthiness.
