摘要：

A secure environment is a top-priority for all the forms of grid computing. To establish trust, traditional grids use various methods, mostly centrally oriented ones, such as certification authorities, VO management servers or credential pools. An ad hoc grid environment is characterized by the absence of a central trusted authority; therefore collaborating entities must establish and maintain a trust relationship among themselves. The paper presents an overview of ad hoc grids, the definitions as well as authorization mechanisms. A proposal for an authorization mechanism to support formation of VOs in ad hoc grids based on intersection of VOs is set out. The mechanism can facilitate the establishment of a trust relationship in cases when standard solutions have failed.
