Distributed Denial-of-Service (DDoS) attacks are one of the major causes of concerns for communication service providers. When an attack is highly sophisticated and no countermeasures are available directly, sharing hardware and defense capabilities become a compelling alternative. Future network and service management can base its operations on equally distributed systems to neutralize highly distributed DDoS attacks. A cooperative defense allows for the combination of detection and mitigation capabilities, the reduction of overhead at a single point, and the blockage of malicious traffic near its source. Main challenges impairing the widespread deployment of existing cooperative defense are: (a) high complexity of operation and coordination, (b) need for trusted and secure communications, (c) lack of incentives for service providers to cooperate, and (d) determination on how operations of these systems are affected by different legislation, regions, and countries. The cooperative Blockchain Signaling System (BloSS) defines an effective and alternative solution for security management, especially cooperative defenses, by exploiting Blockchains (BC) and Software-Defined Networks (SDN) for sharing attack information, an exchange of incentives, and tracking of reputation in a fully distributed and automated fashion. Therefore, BloSS was prototyped and evaluated through a global experiment, without the burden to maintain, design, and develop special registries and gossip protocols.

区块链信令系统 (BloSS)：分布式拒绝服务攻击的协作信令

分布式拒绝服务 (DDoS) 攻击是通信服务提供商关注的主要原因之一。当攻击非常复杂并且没有直接可用的对策时，共享硬件和防御能力就成为一个引人注目的选择。未来的网络和服务管理可以将其操作建立在均等分布的系统上，以抵消高度分布的 DDoS 攻击。协作防御允许将检测和缓解功能结合起来，减少单点开销，并在源头附近阻止恶意流量。影响现有合作防御广泛部署的主要挑战是：(a) 操作和协调的高度复杂性，(b) 需要可信和安全的通信，(c) 缺乏激励服务提供商进行合作，(d) 确定这些系统的运行如何受到不同立法、地区和国家的影响。合作区块链信令系统 (BloSS) 通过利用区块链 (BC) 和软件定义网络 (SDN) 来共享攻击信息、交换激励和跟踪声誉，为安全管理，尤其是合作防御定义了一种有效的替代解决方案以完全分布式和自动化的方式。因此，BloSS 是通过全球实验进行原型设计和评估的，没有维护、设计和开发特殊注册表和八卦协议的负担。协作区块链信令系统 (BloSS) 通过利用区块链 (BC) 和软件定义网络 (SDN) 共享攻击信息、交换激励和跟踪声誉，为安全管理，尤其是协作防御定义了一种有效的替代解决方案以完全分布式和自动化的方式。因此，BloSS 是通过全球实验进行原型设计和评估的，没有维护、设计和开发特殊注册表和八卦协议的负担。合作区块链信令系统 (BloSS) 通过利用区块链 (BC) 和软件定义网络 (SDN) 来共享攻击信息、交换激励和跟踪声誉，为安全管理，尤其是合作防御定义了一种有效的替代解决方案以完全分布式和自动化的方式。因此，BloSS 是通过全球实验进行原型设计和评估的，没有维护、设计和开发特殊注册表和八卦协议的负担。
