Thanks Sri Varshini for your feedback. With regards to your query on 'Exportability' let me try to explain in the best possible way. As we understand, Grid Computing is used to perform complex & huge amount of calculations/analysis for solving a Problem by connecting to large number of computers which are geographically scattered and in diffirent security domains. Hence this demands a strong security policy to be implemented in the network Like User authentication (Only Authroized Users are allowed in the network) , access control (What to Access) , integrity (No Unauthroized Changes to Data) , privacy (Need to Know Basis), and nonrepudiation (Authenticity). To acheive these, 'Encryption' is one of the tool but that should not stop/limit the code/program to be able to exportable and used at a different location/site.
