Security filtering of optical data signals: an approach based on codewords

Security filtering of optical data signals: an approach based on codewords In this paper, we propose an all-optical filtering architecture that filters session establishment and data traffic streams. The session establishment filtering concerns the connection-oriented protocols. Each traffic stream is identified by a traffic identifier composed of a set of optical codewords. Each codeword is formed by a sequence of optical pulses that represent the bit “1” positions. In the case when an information bit “0” is transmitted, the transmitter does not generate a pulse. In a core node that implements the security filtering module, an optical security policy will be applied to the received traffic stream (session establishment or data traffic stream) based on its traffic identifier. The decision after performing the filtering process can lead to accept or reject the traffic stream. The proposed security filtering architecture is mainly composed of two modules: a session and a traffic filtering modules. Photonic Network Communications Springer Journals
