AI总结:

本文研究了在5G NB-IoT中应用后量子密码方案保护TLS的可行性,发现NIST选定的Kyber密钥交换协议开销可接受,但后量子签名方案会导致高延迟和低吞吐量。

摘要:

窄带物联网(NB-IoT)是一种无线通信技术,支持从智慧城市到工业自动化等广泛应用。作为5G扩展的一部分,NB-IoT有望以低功耗和低成本连接数十亿设备。然而,随着量子计算机的出现,即将到来的NB-IoT时代已受到这些设备的威胁,它们可能会破坏适用于大规模保护NB-IoT设备的传统密码算法。在此背景下,我们研究了使用后量子密钥交换和签名算法保护NB-IoT应用的可行性。我们开发了真实的ns-3环境以表征NB-IoT网络特征,并分析了后量子算法在保护通信中的使用。研究结果表明,使用NIST选定的后量子密钥交换协议Kyber不会引入显著开销,但后量子签名方案会导致不切实际的延迟和较低的吞吐量。

英文摘要:

Narrowband Internet of Things (NB-IoT) is a wireless communication technology that enables a wide range of applications, from smart cities to industrial automation. As a part of the 5G extension, NB-IoT promises to connect billions of devices with low-power and low-cost requirements. However, with the advent of quantum computers, the incoming NB-IoT era is already under threat by these devices, which might break the conventional cryptographic algorithms that can be adapted to secure NB-IoT devices on large scale. In this context, we investigate the feasibility of using post-quantum key exchange and signature algorithms for securing NB-IoT applications. We develop a realistic ns-3 environment to represent the characteristics of NB-IoT networks and analyze the usage of post-quantum algorithms to secure communication. Our findings suggest that using NIST-selected post-quantum key-exchange protocol Kyber does not introduce significant overhead, but post-quantum signature schemes can result in impractical latency times and lower throughputs
