Implementing Diffie-Hellman key exchange method on logical key hierarchy for secure broadcast transmission

Abstract

With the rapid growth of the internet, broadcast communication has become an important issue for many different areas and applications. The broadcast communication allows a source to send messages to all or certain group of the users connected to the source. Secure encryption algorithms are often used to ensure that message transmission is secure Today's encryption algorithms, regarded as reliable, include Diffie-Hellman key exchange. In this study, the creation of a common secret key value from the root node to the user is considered and compared with other methods by applying Diffie-Hellman key exchange on Logical Key Hierarchy (LKH) which is a broadcast communication scheme.
