On The Security of PACMAN: Privacy-Preserving Authentication Scheme for Managing Cybertwin-Based 6G Networking

초록

Cybertwin-based cloud-centric networks are attracting considerable attention as new multiaccess edge computing network architecture in 6G networks. However, the sensitive data transmitted between the cybertwin and users/things via wireless communication can be intercepted and hijacked by malicious attackers, resulting in security threats and privacy concerns owing to leakage or abuse. Therefore, secure authentication and key agreement schemes are essential to ensure secure communication in cybertwin-based networks. In 2021, Soleymani et at. presented a privacy-preserving authentication scheme for managing cybertwin-based 6G netoworking (PACMAN). Soleymani et at. claimed that their scheme can satisfy privacy-preserving requirements and resist security threats. However, we demonstrates that PACMAN fails to achieve privacy-preserving requirement. Thus, we suggest the necessary security guidelines to achieve privacy-preserving and resolve the security risks of PACMAN. © 2023 IEEE.
