Is 4G end to end encrypted?

Overall, there are only a few instances where 4G connections have been hacked , versus the many times hacking has happened with private and public WiFi. An example of such instances is the man-in-the-middle attack, which implies hackers eavesdropping between two people or between the user and an app.10 May 2021

However, unlike Wi-Fi connections, mobile data connections are encrypted , adding an extra level of security from outside threats. That’s why security experts like Norton recommend using mobile data instead of Wi-Fi to access sensitive information when you’re out and about.

Wireless 4G LTE network uses 128-bit Advanced Encryption Standard (AES) and SNOW3G algorithms for integrity protection. The 128-bit AES algorithm is the most preferred option in the Wireless 4G LTE network because it has undergone closed observation than other encryption algorithms [4].

The major problem of the 3G/4G network is thus that the encryption is only applicable between the phone and the base station, and there is no encryption applied to the data when it reaches the wired network . To be fully secure, we must overlay our security with SSL/TLS, SSH, or a VPN tunnel.5 Mar 2019
