The rising popularity of the telecommunication networks and their growing support in our every-day life make them a potential target of various security threats and malicious attacks. The international security organizations warn against increasing likelihood of nuclear weapon or electro-magnetic pulse (EMP) attacks, which can be extremely harmful also for the networks. On that background, we study efficient design of a network resilient to the EMP attack wherein the required protection level is provided by the application of multipath routing and military grade bunkers (advanced electro-magnetic radiation resilient approaches protecting whole network node) implementation. Formally, we define and study the problem of bunkers location, routing and spectrum allocation (BLRSA) in an elastic optical network (EON). In the problem objective we address two criteria — network resilience (measured by the average lost flow per potential attack) and spectrum usage. For that problem we propose integer linear programming (ILP) model and two dedicated heuristics — 1S-RSA and 2S-RSA. Then, we perform extensive numerical experiments divided into three parts: (i) tuning of the proposed approaches, (ii) comparison with reference methods, (iii) realistic case study — efficient EMP-resilient network design. In the case study we analyze benefits and costs (especially in terms of the spectrum usage) of the proposed protection scheme. Moreover, we also analyze vulnerabilities of three realistic network topologies to the EMP attacks and identify their critical nodes. The investigation proves high efficiency of the proposed approaches and shows that they allow to save up to 90% of the traffic lost in the case of no protection against these types of attacks.

抗电磁脉冲攻击网络的高效设计——弹性光网络案例研究

电信网络的日益普及及其在我们日常生活中的日益普及使它们成为各种安全威胁和恶意攻击的潜在目标。国际安全组织警告说,核武器或电磁脉冲 (EMP) 攻击的可能性越来越大,这对网络也可能是极其有害的。在此背景下,我们研究了对 EMP 攻击具有弹性的网络的有效设计,其中所需的保护级别是通过应用多路径路由和军用级掩体(保护整个网络节点的高级电磁辐射弹性方法)实现来提供的。正式地,我们定义并研究了弹性光网络 (EON) 中的掩体位置、路由和频谱分配 (BLRSA) 问题。在问题目标中,我们解决了两个标准——网络弹性(通过每次潜在攻击的平均丢失流量来衡量)和频谱使用。对于这个问题,我们提出了整数线性规划 (ILP) 模型和两个专用的启发式算法——1S-RSA 和 2S-RSA。然后,我们进行了广泛的数值实验,分为三个部分:(i ) 调整所提出的方法,( ii ) 与参考方法的比较,( iii ) 现实案例研究——高效的 EMP 弹性网络设计。在案例研究中,我们分析了拟议保护方案的收益和成本(尤其是在频谱使用方面)。此外,我们还分析了三种现实网络拓扑对 EMP 攻击的漏洞并确定了它们的关键节点。调查证明了所提出的方法的高效率,并表明在没有针对此类攻击的保护的情况下,它们可以节省高达 90% 的流量损失。
