“…Physical-layer attacks in optical networks have been categorized according to those aimed at gaining unauthorized access to the carried data or those causing service degradation [1]- [3], [5], [6], the latter of which is considered in this paper. Service degradation attacks generally involve inserting malicious signals into the network, such as optical signals of excessive power (e.g., 5-20 dB above other, legitimate signals), to degrade other user connections.…”

“…In this paper, we consider the propagation scenario where an attacking signal inserted on any legitimate connection could potentially compromise all other connections sharing common links with it, as well as connections assigned the same wavelength and traversing common switches with it. 1 This assumption models the primary propagation of in-band high power jamming attacks in FOADM-based networks, where all connections co-propagating with the original attacking signal can be degraded. We consider in-band jamming in FOADMbased networks since a connection protected from such an attack would also inherently be protected from an analogous attack in ROADM-based networks, as well as out-of-band jamming attacks and mixed modulation attacks in MLR or elastic networks, where propagation is more limited.…”

Abstract-Due to the high data rates in optical networks, physical-layer attacks targeting service degradation, such as power jamming, can potentially lead to large data and revenue losses. Conventional network survivability approaches which establish link-disjoint working and backup paths to protect from component faults may not provide adequate protection for such attacks. Namely, the working and the backup paths, although link-disjoint, might both be affected by a single attack scenario due to specific attack propagation characteristics. To enhance the existing survivability approaches, we utilize the concept of an attack group (AG) which incorporates these characteristics to identify connections which can simultaneously be affected by a single attack. We apply this concept to dedicated path protection (DPP) and develop attack-aware DPP (AA-DPP) approaches which aim to establish AG-disjoint primary and backup paths in a cost-effective manner. We provide a two-step ILP formulation for the routing and wavelength assignment of the working and backup paths, as well as a heuristic for larger problem instances. Numerical results indicate that the proposed approaches provide dedicated path protection schemes with enhanced attack protection without using more resources (i.e., wavelengths, average path lengths) than standard DPP methods.

“…Recently, the issues and level of physical-layer security potentially supported by O-CDMA are under investigation [18]- [22]. It is important to have optical codes with huge cardinality and to continuously and rapidly switch codewords in order to substantially increase an eavesdropper's difficulty in decoding the codewords and, in turn, the transmitted data bits of the attackee.…”

“…Thus, optical codes, such as optical orthogonal codes and prime codes [1]- [17], have been designed with good auto-and crosscorrelation properties in order to optimize the discrimination between the correct (address) codeword and interfering codewords. Recently, due to the tremendous growth in the volume of information transfer and strong demands in security and privacy, the issues and level of physical-layer security potentially afforded by O-CDMA have become an interesting research topic [18]- [22]. New families of two-dimensional (2-D) wavelengthtime algebraic optical codes with flexible choices of code parameters and cross-correlation functions, and large cardinality were constructed in [23]- [25].…”

Algebraic optical codes with large cardinality and unique tree structures of multiple levels of subsets of codewords for adjustable code performance and cardinality have recently been proposed. As shown in this paper, these characteristics support new network architecture and applications for rapid code switching and physical-layer security in optical code-division multiple access networks. In addition, a new "translate" method of converting "additive" error-correction codes (ECCs) into this kind of optical codes is investigated and demonstrated with four families of ReedSolomon codes. With rich families of ECCs, our method enhances the collections of optical codes. The performances of these "treestructured" optical codes are algebraically analyzed and verified, for the first time, using the weight distribution of ECCs.Index Terms-Error-correction codes, optical code division multiple access (O-CDMA), Reed-Solomon (RS) codes, tree structure.

“…Although cryptography techniques are usually implemented in the presentation layer of Open Systems Interconnection (OSI) reference model, overall security is improved when data are encrypted in multiple layers [2]. This strategy encompasses the physical encryption of signals in the optical layer.…”

We investigate the application of a new all-optical cryptography technique to wavelength division multiplexing (WDM)-compatible differential phase-shift keying (DPSK) signals. The technique uses current optical band-pass optical filters with narrow bandwidths to divide a given input WDM-compatible signal into several spectral slices, which are submitted to two cryptographic key stages. The first one impresses amplitude encoding, whereas the second imposes delay variations to each spectral slice. The technique performance is assessed by evaluating the encrypted and decrypted signals bit error rates. Computer simulations suggest that encrypted DPSK signals may be properly recovered even after being propagated through typical metropolitan area network distances. 1
