Experimental results about basic characteristics of iCOP model
Basic characteristics of iCOP Security Model
Host A: General host, Host B: iCOP host
Future Work:•With experiments, we have tested basic characteristics of iCOPhost•In our future work, we would evaluate iCOP architecture by different parameters with different kinds of complex applications
