5G Security Feature: IMSI Encryption. The SIM card contains a unique user identifier called an International Mobile Subscriber Identity (IMSI), comprised of your country code, wireless provider code, and phone number . The IMSI is key to authenticating your device as it travels on the network.12 Haz 2019
Read moreHow is 5G more secure than 4G?
5G gives secure, fast service more reliably than 4G due to better use of bandwidth and more connection points . With less stress on the network, data costs can fall lower than 4G networks. 5G can carry more devices than 4G as it expands the available radio waves.
Read moreWhat data does 5G use?
Like other cellular networks, 5G networks use a system of cell sites that divide their territory into sectors and send encoded data through radio waves . Each cell site must be connected to a network backbone, whether through a wired or wireless backhaul connection.

For the first time, your connection is shielded from rogue devices that may capture phone calls by mimicking cell towers . Your ID with 5G is encrypted. Plus, a more robust encryption algorithm scrambles the traffic when your voice and data travels from your device to the cell tower.
Read moreWhat is TLS in 5G?
TLS is a cryptographic protocol that provides end-to-end communications security over networks by encrypting data and authenticating connections when moving data over the internet . In the 5G SA core, TLS offers the highest levels of encryption and privacy.
Read moreWhat encryption is used in 4G?
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].
Read moreDoes 5G use IMSI?
That said, the new 5G security protocols do give the MNO the flexibility to support law enforcement when needed. Since the MNO controls the security and privacy of the IMSI from the SIM to the network , it can still work with agents to monitor approved criminal targets.
