Abstract

The upcoming 6G networks will support an unprecedented number of connected devices, thus greatly expanding the attack surfaces. Access authentication helps mitigate these threats, but may introduce prohibitive costs due to massive connections operating in high-frequency bands on resource-constrained devices. This motivates the proposal of SeaAKA, a novel protocol designed to achieve efficient authentication in 6G networks. The SeaAKA protocol implements seamless group-based cross-layer authentication through a novel voting mechanism that coordinates physical-layer authentication (using lightweight approaches) with upper-layer verification (employing Shamir’s secret sharing). This integration reduces computational and communication overhead during repeated authentication cycles while maintaining high accuracy. Security analysis using BAN logic confirms SeaAKA’s resilience against replay attacks along with data integrity/privacy preservation. Evaluations demonstrate SeaAKA’s superior efficiency over existing methods, reducing communication overhead from 4.244 to 0.0006 ms and computational overhead from 2,432 to 512 bits.
更快更安全:6G无缝组跨层认证和密钥协议
即将到来的6G网络将支持前所未有的连接设备数量,从而大大扩展攻击面。访问身份验证有助于减轻这些威胁,但由于在资源受限的设备上在高频频带上运行大量连接,可能会带来过高的成本。这激发了SeaAKA的提出,这是一种旨在在6G网络中实现高效身份验证的新协议。SeaAKA协议通过一种新颖的投票机制实现了无缝的基于组的跨层身份验证,该机制协调了物理层身份验证(使用轻量级方法)和上层验证(使用Shamir的秘密共享)。这种集成减少了重复身份验证周期中的计算和通信开销,同时保持了较高的准确性。使用BAN逻辑的安全分析证实了SeaAKA对重放攻击的弹性以及数据完整性/隐私保护。评估表明,与现有方法相比,SeaAKA的效率更高,通信开销从4.244毫秒减少到0.0006毫秒,计算开销从2432位减少到512位。

期刊介绍: The IEEE Communications Letters publishes short papers in a rapid publication cycle on advances in the state-of-the-art of communication over different media and channels including wire, underground, waveguide, optical fiber, and storage channels. Both theoretical contributions (including new techniques, concepts, and analyses) and practical contributions (including system experiments and prototypes, and new applications) are encouraged. This journal focuses on the physical layer and the link layer of communication systems.
