The diversity of capability of computers worker in distributed system influences resource allocation
and completion time for each jobs on the system. This study aims to implement a dynamic load balancing
technique using dynamic distribution upon demand (DDD) algorithm to optimize the resource allocation in
distributed data encryption/decryption system. Evaluating was performed by comparing the proposed system
with two other models that is a system without load balancing and with static load balancing method.
Evaluation result showed that the resource allocation in the proposed system using DDD algorithm more
optimized and at the decryption process of three and four characters with proper workload initialization
values presented that the job completion time much faster than the two other systems..
