Optical burst switching is an optical network technology that helps in improving the use of the optical networks resources. In OCS, the network is configured to establish a circuit, from an entry to an exit node, by adjusting the optical cross connects circuits in the core routers in a manner that the data signal, in an optical form, can travel in an all-optical manner from source to destination node. This approach suffers from all the disadvantages known to circuit switching - the circuits require time to set up and to destroy, and while the circuit is established, the resources will not be efficiently used to the unpredictable nature of network traffic. Security is one of the major problems in field of networks. Mainly this work focused on security issues in optical burst switching and to decreased the energy consumption. In this research work, a secure public key cryptography technique is proposed and evaluated as a security solution to measure security threats related to burst packet in optical burst switching networks.
