Abstract

This paper presents OPCUA binary protocol from telecommunication point of view by using OSI-network model as a basis. Presented architecture is based directly on OPCUA specifications and Java reference implementation. Practical interest is focused on OPCUA security and its feasibility for real world applications. The impact of enabling security in OPCUA is measured by benchmarking performance of current Java default implementation.
