Correspondence protocols are required for the trading of information between texture layer assets. Correspondence necessities incorporate routing, transport and naming. Confirmation protocols are required for correspondence administrations for giving secure instruments to approve the validation of clients and assets. Connectivity layer gives validation administrations which have the accompanying qualities:

 Single sign on: Clients must have the capacity to approve themselves (“sign on”) just once and after that they simply approach numerous grid assets depicted in texture layer.

 Delegation: The user should have the ability to run a program for its own benefit, with the goal of finding out whether the program is fit to get the grid resources which the verified user is entitled to.

 Integration with various local security solutions: All sites and resource suppliers ought to be incorporated with different nearby security arrangements.
