In order to authenticate users and other services, grid services need to maintain a list of certificate authorities, which they trust as a source for issuing credentials. Grids inherently span multiple institutional administration boundaries and aim to provide support for the sharing of applications, data, and computational resources in a collaborative environment. In this environment there may exist hundreds of certificate authorities, each issuing hundreds if not thousands of certificates. In such a dynamic multi-intuitional environment with tens of thousands of users, credentials will be issued and revoked fairly frequently. One underlying problem in this vision is how to provide a grid-wide mechanism for maintaining and provisioning trusted certificate authorities, such that grid services may make authentication decisions against the most up to date information. In this talk we will present the design and implementation of the Grid Trust Service (GTS), a federated framework for the creation and management of a grid trust fabric, enabling the provisioning of certificate authorities.
