Thales High Speed Encryptors – Delivering on the Promise of 5G

5G download speeds can reach 10 gigabits per second, up to 100 times faster than 4G, and supports millions more devices with improved coverage and reliability. 5G connectivity brings new capabilities such as IoT, virtual reality, gaming, remote surgeries, real time mass-data updates for mobile devices, connected cars, sensors, etc. 5G users will benefit from more connections, with fewer drops and less interference while enjoying remote access from almost anywhere. While 5G creates extraordinary opportunities for people and businesses, it also introduces unique technical and security challenges.

5G and the data explosion

The introduction of 5G networks presents unparalleled challenges for securing data in motion. With higher speeds and expanded network capacity of 5G, there will be more data in motion than ever, this is undeniable and network architectures are being designed to meet the demand. According to Ericsson’s Mobility Report 2022, mobile consumers devour an estimated 90 exabytes a month, aka 90 billion gigabytes! However, this number is projected to reach 325 EB per month in 2028.

This data explosion needs to be secured efficiently and to the highest commercial standards throughout the network but particularly from the RAN to the edge data center and back to the core of the network where mass amounts of data will be aggregated and moved in large scale. The more data we push, the more harvest and decrypt attacks become worthwhile to hackers. Data injection, misdirection and capture are real threats, and the more data that flows through the network the more likely we are to see large scale surveillance and collections programs. The underlying trust to the 5G network will be critical for widespread adoption.

As 5G scales out, adding more connectivity and capacity to the network, it will allow for greater simultaneous interactions and more data at higher speeds flowing to the edge. In addition to reduced speeds and capacity issues, the processing of legacy encryption can slow down the network by increasing latency and jitter. Latency budgets can be 1milli-second or less. Poor performing legacy encryption solutions can chew up a large portion of a 5G networks latency budget. Increased latency and jitter wreak havoc on real time appli
