Paper Abstract

We propose the new secure key management scheme for SDH-based WDM AON. The problem that is to have no overhead data for security service on SDH format may be overcome easily by using the proposed key management scheme. The major advantages of the proposed architecture are that the end-to-end security service can be offered and the key management of a cryptosystem can be implemented easily. The proposed secure SDH-based WDM AON architecture have the property of tapping resistance : the key management channel can monitor any tapping attack using the cutoff wavelength of the fiber ; the encryption function of the optical cryptosystems can prevent eavesdroppers from understanding information by tapping. In addition, the proposed architecture can ensure that synchronization of key stream sequence between the optical cryptosystems is maintained perfectly and security management for APS can be performed easily. The proposed architecture can be applicable to the secure node system.
