Zusammenfassung
In a communicating system, information transmitted from one location (sender) to another (receiver) is
secured or protected from unauthorized users or intruders. Many cryptographic algorithms have been used
to prevent and protect data and information from being hacked by intruders. Both symmetric and
asymmetric algorithms have not been successful in simulating cryptosystems as real-world issues with
things enclosed in properties and procedures. This research simulates the Diffie Hellman key exchange
algorithm using object-oriented analysis and design techniques. The researchers used the Unified
Modeling Language tools in the analysis and design of the system and implemented the Diffie Hellman key
exchange algorithm using C++ object-oriented programming language. The outcome demonstrates that
cryptosystems are actual issues with entities having encapsulated properties and functions.
