industryopinion Unleashing 5G Core: Overcoming the barriers of
decryption and data visibility Rob Pocock, Technical Director at Red Helix, discusses the importance of overcoming the barriers of decryption and data visibility.
T
he rollout of next generation network connectivity is always a source of excitement for businesses and users alike, introducing us to heighted
capabilities and conveniences. 3G technologies brought us new levels of connectivity when on the move, then 4G arrived to greatly improve our connection speeds. Now we have 5G, and 6G is already being discussed 5G is set to provide even more

opportunities for users through enhanced mobile broadband offerings, the reality of massive Machine Type Communications (mMTC) and ultra-reliable low latency communications. This offers a breadth of new possibilities from industrial automation to self- driving vehicles and connecting a network of IoT devices with ease. However, for businesses and users to reap the true benefits of 5G,
operators and those delivering the service have some fundamental challenges to overcome. 5G rollouts are already behind where they need to be, due to delays caused by the pandemic, skills

the fact that control plane data in the 5G core requires higher levels of encryption due to new security risks brought about by the growth in use cases for 5G. Legislation requires that data be encrypted on the control plane using the latest version of transport layer security _ TLS1.3. However, this is harder to decrypt, meaning operators have to either sacrifice visibility or commit to testing using unencrypted data – with many holding back on introducing this strong new encryption standard.
On top of this, capacity remains largely untested, as
the expansion and adaptation of new devices that could use 5G hasn’t existed before. This means there is no model to follow, leaving operators in the dark when it comes to knowing how robust and reliable their network really is. Instead of offering customers untold opportunities to scale through 5G and beyond, they could leave them with ineffective solutions and highly vulnerable to cyberattack.
The impact of 5G delays 5G is set to revolutionise the way we connect. Not only is it faster, with speeds projected to be upwards of 100 times quicker than that of 4G, but it also offers low latency and high bandwidths, allowing applications and communications running on 5G networks to share data in near real-time – holding huge potential for the Internet of Things (IoT) and automation, and acting as a driving force for the Fourth Industrial Revolution. Yet, with such prominent implications,
delays to the implementation of 5G hold severe consequences. In a report from the
