An innovative idea is created by changing the irreducible polynomial of finite field in S-BOX, Mix Column, and Shift-Row to organize a diversified encryption system through a designed Configure-File different from the channel of key management. Within the large organization, the inter communication-linked can be limited for mutual understanding using the variation of parameters of DAES in the same organization. One of the advantage is that the entire organization uses the same password, any unit can only accept the the required information from the closely related units. If the key is stolen or damaged, there is no immediate hazard to this organization. This configuration may also be the key factors for intrusion detection. This study provides the features in DAES to increase robustness of key management and wider system utilization, scalability and flexibility.
