What does "Mutual Authentication" mean?

Table of Contents

Mutual authentication is a process where both parties in a communication verify each other's identity before sharing sensitive information. This practice ensures that not only does the user prove who they are, but the network also confirms its identity.

In modern mobile networks, especially those that use small cells and advanced technology, mutual authentication plays a crucial role in keeping data safe. By ensuring that both the user and the network are who they claim to be, it helps prevent unauthorized access and fraud.

This two-way verification is important for maintaining privacy and security, especially in environments where many users are connected, such as in 5G networks. It reduces the risk of attackers impersonating either the user or the network, which can lead to serious security issues.

In summary, mutual authentication helps create a safer communication environment by making sure that both sides of a connection trust each other.
