Abstract

Researching fibre optic security vulnerabilities suggests that not everyone who is responsible for their networks security is aware of the different methods that intruders use to hack virtually undetected into fibre optic cables. This paper will briefly discuss the vulnerabilities in fibre optic systems and how they can be better protected. Knowing the security risks and knowing the options available may save a company a lot embarrassment, time, and most importantly money.

Secure Fiberoptic Communications

H. Hodara

At the heart of our current information explosion is the communication network. Networks are now an intrinsic part of our daily activities, whether they are for Internet business transactions or military communications in Future Combat Systems. Protection of this communication infrastructure is a must. In this article, we discuss two approaches for securing all-optical networks. The first is an optical encryption technique that denies the information to intruders. The second is an authentication scheme capable of detecting and identifying unauthorized users.

Fiber Optics Communication is also one of the major branch which is widely used in current communication world. Due to several advantages of fiber optics communication over different conventional wired communication method it is having higher priority. Though fiber optic transmits large amount of data quickly over long distance, it is vulnerable to various security attacks. The fiber optic cable can be easily tapped. Fundamental improvements can be achieved for the entire network by increasing the optical network’s performance in terms of channel capacity, data rate, and processing speed. Furthermore, the security of the optical network has an impact on the security of the entire communication system. Optical network security can be effectively protected by fiber-based methods, including all optical signal processing, optical key distribution, optical steganography, and optical chaos-based communication. Fiber-based devices do not radiate an electromagnetic signature and are immune to electromagnetic interference. To provide end to end secure fiber optic communication, a special encryption algorithm based on Advanced Encryption Standard (AES) is employed. The proposed encryption algorithm is simulated and the performance is analyzed. In this paper we are mostly dealing with the basics of fiber optics working principle, priority over other conventional communication system and role of fiber optics communication in computer networking and its vulnerabilities.

Quantum cryptography is the result of a synthesis of ideas from fundamental quantum physics and classical encryption that may radically change the way in which the confidentiality of information and the integrity of communications networks are protected. In this paper we discuss the issues that influence the design of practical quantum cryptography schemes for optical fibre-based communication systems.

Optical Layer Security in Fiber-Optic Networks

Mable P. Fok, Zhexing Wang, Yanhua Deng +1 more

The physical layer of an optical network is vulnerable to a variety of attacks, including jamming, physical infrastructure attacks, eavesdropping, and interception. As the demand for network capacity grows dramatically, the issue of securing the physical layer of optical network cannot be overlooked. In this survey paper, we discuss the security threats in an optical network as well as present several existing optical techniques to improve the security. In the first part of this paper, we discuss various types of security threats that could appear in the optical layer of an optical network, including jamming, physical infrastructure attacks, eavesdropping, and interception. Intensive research has focused on improving optical network security, in the above specific areas. Real-time processing of the optical signal is essential in order to integrate security functionality at the physical layer while not undermining the true value of optical communications, which is its speed. Optical layer security benefits from the unique properties of optical processing-instantaneous response, broadband operation, electromagnetic immunity, compactness, and low latency. In the second part of this paper, various defenses against the security threats outlined in this paper are discussed, including optical encryption, optical code-division multiple access (CDMA) confidentiality, self-healing survivable optical rings, anti-jamming, and optical steganography.

Technological developments in fiber-optic communications introduce new technologies with their own set of vulnerabilities. Vulnerability issues at the optical layer are explored to the degree necessary to lay a foundation for the development of security measures to protect the communications infrastructure and communications signal. Several means of infusing security into the development of new optical communication devices and optical fiber technology are presented.
