“…Both techniques are built on top of previously explored techniques, such as orthogonal coding, and scrambling via a random monomial matrix. [2] As a result of combining all these techniques, the only randomness shared between sender and receiver is the nonzero content of the random (scrambling diagonal times monomial) code matrix. The encryption algorithm goes as follows: the data stream is split among n-m streams and the frameless noise stream is split among m streams in the system, varying in time among the total of n streams in the system.…”

“…[1] The approach is based on the early proposal that scrambling of the phase of the combined aggregate of OCDM codes in use increases the search space beyond the reach of an exhaustive search attack. [2] The solution has been demonstrated in the laboratory for an aggregate 40 Gb/s over 400 km transmission distance. [3] However, robustness against known plaintext (KPT) attacks was questioned by showing with some idealized assumptions that the search space is dramatically reduced from p n to p (n-m) , where n is the number of phase-locked wavelengths and also the maximum number codes available, (n-m) is the actual number of codes in use and p is the number phase states supported by the scrambler [4].…”

We introduce two novel techniques, random noise on unused channels and varying the inter-code phases on realistic framing repetition, to obtain an OCDM-based encryption scheme for which we can prove desirable security guarantees.OCIS codes: (060.4250) Networks; (060.4785) Optical security and encryption Introduction: Optical code division multiplexing (OCDM)-based security by obscurity has been promoted as a scaleable "security" solution for spectral-phase encoded OCDM systems operating at aggregate data rates of 100 Gb/s and beyond that can be realized with available technology through inverse multiplexing of 10 Gb/s tributaries, each carried on a OCDM code.[1] The approach is based on the early proposal that scrambling of the phase of the combined aggregate of OCDM codes in use increases the search space beyond the reach of an exhaustive search attack.[2] The solution has been demonstrated in the laboratory for an aggregate 40 Gb/s over 400 km transmission distance.[3] However, robustness against known plaintext (KPT) attacks was questioned by showing with some idealized assumptions that the search space is dramatically reduced from p n to p (n-m) , where n is the number of phase-locked wavelengths and also the maximum number codes available, (n-m) is the actual number of codes in use and p is the number phase states supported by the scrambler [4].

This paper is for transmission of video data using optical code division multiple access (OCDMA) system over WDM. OCDMA system is proposed for supporting large numbers of subscriber in optical access network. The system performance is analyzed using Modified Double Weight (MDW) Code because it help to decrease the Multiple Access interference (MAI) to great extend at the transmitter side. Also at the receiver side we use the NAND subtraction technique to detect the signal. Using network simulation we conclude that this system gives better results compare to OCDMA system using MDW code. We also ascertained by simulation that NAND subtraction technique highly improves BER performance of the system compare to other detection techniques.
