Securing Optical Burst Switched Networks

摘要

Optical Burst Switching (OBS) allows variable size data bursts to be transported directly over DWDM links without encountering O/E/O conversion. This paper identifies potential threats to security in OBS networks. To alleviate the security threats, we propose a Secured Optical Burst Switching (S-OBS) framework that, for the first time, brings security measures to the OBS networks. The contributions of the paper are summarized as follows: 1) This is the first paper that identifies the potential security problems in OBS networks; 2) We have proposed a security framework for OBS networks; 3) We have proposed two levels of security measures to be incorporated into OBS networks, namely, authentication of burst headers and confidentiality of data bursts; 4) We have examined the candidate solutions in each category, and suggested the solutions that are well suited to OBS networks.
