The Internet Engineering Task Force (IETF) is guiding the mobile industry in adopting new security methods to protect networks against future quantum computers. At a recent IETF meeting, experts from Ericsson explained that mobile networks must switch to quantum-resistant encryption to maintain global standards like 4G and 5G. This transition is urgent because mobile infrastructure is heavily regulated and must remain secure for devices that last for many years, including small IoT sensors with limited battery and memory.
Industry plans indicate that 5G networks will begin integrating these quantum-safe algorithms between 2027 and 2028, while future 6G systems are being built to be secure from the start. A key challenge is updating the digital systems that verify software updates and device identity, ensuring they remain trustworthy over decades. This migration aims to balance strict government security requirements with the need to keep mobile networks fast and cost-effective for users worldwide.
