ABSTRACT The general aspects and basic assumptions of the fifth‐generation (5G) networks have been well‐researched. This research mainly concerns security for the planned 5G wireless systems, the problems encountered, suggestions, and measures for strengthening the security and privacy of the 5G system. Such networks enable faster machine control, issues identification, performance evaluation, and data access. At the same time, transmitting IoT nodes' interactions over insecure wireless channels can be beneficial and raise issues simultaneously. These channels, although separated from the actual industrial premises, can be used by unauthorized nodes to collect data and gain control of industrial devices. Such risks can be managed using secure sessions, but achieving secure sessions over insecure channels forms a major challenge. For this, variable identification (VID) is used as an authentication method and key exchange technique for the authorized IIoT nodes, limiting the unauthorized IIoT node access. VID uses several types of lightweight pseudonyms that are changed after a certain time and are randomly selected from a set of pseudonyms predefined in the home networks and terminal apparatus. These pseudonyms shield against different threats, including forgery, replay attacks, tampering, impersonation, and man‐in‐the‐middle attacks. To assess the properties of the proposed system, the ProVerif tool is used for simulation, and results demonstrate that the system is free from possible attacks.
