Quantum computing has the potential to revolutionize various industries, from healthcare to transportation, but its impact on cybersecurity cannot be ignored. The widely used RSA encryption algorithm, which relies on prime numbers, is at risk of becoming obsolete once quantum computers become powerful enough to crack it. Telcos worldwide are facing the challenge of implementing new cryptography practices to ensure data security.
While the development of fully functional quantum computers is still distant, experts estimate that it may take another 25 years before RSA can be broken. However, the need to act now is crucial due to the long process of updating telecom security systems. It will take time to develop, test, and implement post-quantum algorithms that can withstand the power of quantum computing.
One potential solution that many telcos are exploring is quantum key distribution (QKD). QKD involves generating and distributing cryptographic keys based on quantum mechanics, making any intrusion by a third party visible. However, there are debates within the industry regarding the effectiveness and practicality of QKD as the sole solution.
Hardware is a significant challenge in implementing QKD. Single photon detectors are expensive and complex, and ensuring their reliability and randomness is crucial. Telcos are also considering post-quantum cryptography as an additional layer of security alongside QKD. This approach relies on algorithms and is less complex to implement, making it a more accessible solution for many companies.
BT, along with other telcos, has been actively involved in QKD trials. The company has partnered with Toshiba and AWS to test the technology’s feasibility in real-world financial use cases. While scaling the technology and addressing aggregation challenges remain areas of focus, the trials have provided valuable insights for future projects.
As the telecom industry prepares for the quantum era, a combination of QKD and post-quantum cryptography is likely to be the approach taken to ensure data security. While the timeline for fully functional quantum computers is uncertain, telcos are proactively working to stay ahead of the curve and protect sensitive information. Through ongoing research, collaboration, and advancements in hardware and algorithms, the telecom industry aims to strike a balance between the challenges of quantum computing and the solutions needed for a secure future.
