Multi-User Secret Key Generation for WSNs via Wireless Channels

IEEE Open Journal of the Communications Society
Wireless sensor networks (WSNs) are resource-constrained and highly vulnerable to eavesdropping due to their broadcast nature. Traditional symmetric key cryptography provides strong security but imposes excessive computational and energy demands on ...

Power Allocation and Beam Scheduling for Multi-User Massive MIMO Secret Key Generation

IEEE Access, 2020
Secret key generation in multi-user massive multiple-input multiple-output (MIMO) communication suffers from high computation complexity, pilot overhead, and inter-user interference caused by the large dimension of the massive MIMO channel.

Secret underwater acoustic key generation challenged by Eve's simulator

, 2023
Symmetric cryptography is the de-facto approach to information security for ad-hoc underwater acoustic networks. The requirement is that all network nodes possess the same cryptographic keys and key distribution that happens offline.

Secret Key Generation Protocol for Optical OFDM Systems in Indoor VLC Networks

IEEE Photonics Journal, 2017
Although the visible light communication (VLC) channel has superior security than radio frequency channels, its broadcast character makes VLC links vulnerable to eavesdropping. Therefore, VLC networks need to support security to protect the user's
