Application of a key generation and distribution algorithm for secure communication in open systems interconnection architecture

A key generation and distribution algorithm is presented in this paper and shown applied for secure transmission of user data between two peer-layers of an Open Systems Interconnection Reference Model Architecture located at any source and destination end-user host systems. In particular, the algorithm (i) generates and distributes a session key between two peer-layers during Connection Establishment phase, (ii) encrypts and decrypts their user data, present in the Protocol Data Unit, using the same session key during Data Transfer phase, and (iii) after transmitting user data, it destroys the session key during Connection Release phase. For simulation purpose, the algorithm is shown applied between the transport service user and provider, present at the source and destination host systems, for secure transfer of transport service user data to the corresponding remote peer layer using Class 4 Transport Protocol of OSI-RM Architecture.
