摘要:

未来的无线网络必须以高数据率服务于密集的移动网络,将能量需求保持在可能的最低限度。基于小小区的网络架构和设备到设备(D2D)通信已经被认为是5G网络及以后的一部分。在这样的环境中,可以采用网络编码(NC)来实现更高的吞吐量和能量效率。然而,支持NC的系统需要解决NC特有的安全挑战,例如污染攻击。所有对抗污染攻击的完整性方案通常都需要适当的密钥分发和管理,以确保移动环境中的安全性。此外,小型小区环境中的移动性要求在信令开销方面更具挑战性和要求。本文提出了一种针对基于MAC的完整性方案定制的区块链辅助密钥分发协议,该协议与上行链路参考信号(UL RS)切换机制相结合,实现了节能的安全NC。该协议在切换过程中的性能分析表明,它的适用性,以确保高水平的安全性,防止污染攻击,在密集的小小区环境与多个对手存在。此外,所提出的方案实现了较低的带宽和信令开销在切换过程中相比,传统的方案和信令成本显着降低通信的进展,从而提高了网络的累积能量效率。

英文摘要:

Future wireless networks must serve dense mobile networks with high data rates, keeping energy requirements to a possible minimum. The small cell-based network architecture and device-to-device (D2D) communication are already being considered part of 5G networks and beyond. In such environments, network coding (NC) can be employed to achieve both higher throughput and energy efficiency. However, NC-enabled systems need to address security challenges specific to NC, such as pollution attacks. All integrity schemes against pollution attacks generally require proper key distribution and management to ensure security in a mobile environment. Additionally, the mobility requirements in small cell environments are more challenging and demanding in terms of signaling overhead. This paper proposes a blockchain-assisted key distribution protocol tailored for MAC-based integrity schemes, which combined with an uplink reference signal (UL RS) handover mechanism, enables energy efficient secure NC. The performance analysis of the protocol during handover scenarios indicates its suitability for ensuring high level of security against pollution attacks in dense small cell environments with multiple adversaries being present. Furthermore, the proposed scheme achieves lower bandwidth and signaling overhead during handover compared to legacy schemes and the signaling cost reduces significantly as the communication progresses, thus enhancing the network's cumulative energy efficiency.
