Abstract:
This paper presents a security layer for authentication and confidentiality called CASGrid. To implement it was used asymmetric encryption and digital certificates. The CASGrid was implemented in SETolF grid. The paper is organized into two parts: first part provides authentication of users using digital certificates. Thus, certification authority was attached to grid, providing certificates. The authentication happens through the validation of client’s certificate public key. The second part implements a Insurance Virtual Channel, based on session keys and asymmetric encryption. It provides integrity and confidentiality in messages exchange after the User Authentication.
