Spread Spectrum over OFDM for Enhanced Security in Elastic Optical Networks

In this work, spread spectrum with signal overlapping techniques are used to secure confidential connections against eavesdropping. Routing and spectrum allocation algorithms are proposed in order to establish a set of confidential and non-confidential connections in elastic optical networks, while considering spectrum utilization and enhanced security.© 2018 IEEE.
