In order to enhance data transmission security within internet network, this paper consider a signature reconfiguration scheme over wavelength-coded network coder/decoders (codecs). We propose the reconfiguration scheme of composite signatures in which optical network codecs reconfigure their signature keys in a tractable way to enhance system confidentiality for coded wavelength-division multiplexing (WDM) transmissions. Based on conventional maximal-length sequence (M-sequence) codes over arrayed-waveguide-grating (AWG) codecs, composite signatures of relative prime-length M-sequence codes are structured to identify network node users. Network codecs change their signatures dynamically such that eavesdroppers cannot keep up with the speed of code changing, and thus unable to detect the channel waveform to descramble the code. Evaluated results show the effectiveness of the proposed approach via composite signatures reconfiguration against practical eavesdropping.
