While this technology is set to revolutionize several industries, it also brings with it ongoing challenges in cyber security. Traditional coding techniques can be disrupted by the capabilities of quantum computers, which can solve problems in a matter of minutes, compared to thousands of years for conventional computers. This highlights the importance of security management systems in the telecommunications industry, which are closely related to the transmission and protection of sensitive data.
The rise of quantum risks
Quantum computers work according to the principles of quantum mechanics, which means they use the four fundamental principles of quantum physics. Instead of bits, they are qubits. And quantum computing is a science in itself, so maybe we can leave that to another topic. What is important to note is that, because of this, quantum computers can perform multiple calculations at the same time. This ability allows them to break the most commonly used algorithms, such as RSA and ECC, which protect most messages on the Internet today. For telecoms, this means that when quantum computers become powerful and widely available, the security of encrypted messages, customer data and online services will be at risk. Experts predict that even today’s secret information can be stored by bad people and deciphered later, as computers become more powerful or easier to access.
The mobile communications sector: a key target
Business, personal and government information held by telecommunications companies makes them vulnerable to cyber-attacks. The network of this sector is very important for international communication, economy and national security. Telecommunications companies must switch to quantum computing-resistant encryption to protect their networks from accidental tampering, as quantum computing can bypass traditional encryption.
Organizations in the telecommunications sector have already started to take action, complying with the rules and regulations. For example, the US government has ordered government agencies to start using post-quantum cryptography (PQC) security through the Quantum Computing Cybersecurity Preparedness Act. Likewise, the Monetary Authority of Singapore encouraged companies to take action by publishing guidelines to mitigate cybersecurity risks.
Post-quantum cryptography
In response to this, technology companies and researchers are working on post-quantum encryption methods that withstand the potential of quantum decryption. Companies such as Google and Apple began experimenting with quantum security cryptography in 2024 to keep pace with emerging technologies. Google has incorporated security protocols into the bulk of its internal messaging, while Apple built the PQ3 system to protect iMessage from any future attacks.
In response, the National Institute of Standards and Technology (NIST) has selected four security solutions as winners of a six-year competition. These algorithms are designed to provide strong protection against the threat posed by quantum computing, enabling companies including telecommunications companies to use systems that can handle quantum computing.
New experiences
The security evolution of quantum computing brings its own challenges. Many telecommunication devices rely on old systems that are incompatible with modern cryptographic history. Companies need to look at their systems, estimate the time needed to change some security measures and decide what is necessary to make this happen.
However, quantum computing also offers exciting opportunities in the quantum world. It has the ability to unlock new skills and solve problems in various fields, including telecommunications. It has the potential to advance areas such as network optimization, traffic management and even create more secure communication methods, such as quantum key distribution (QKD), which uses quantum mechanics principles to secure communications.
Preparing for the quantum future
Telecommunication companies need to act quickly, plan accordingly to mitigate the risks of proliferation and prepare for their future. The idea is that if you start thinking about quantum computing when it’s already here, it’s already too late. As quantum computing develops, organizations need to use quantum-resistant cryptography, review their data protection strategies and adopt new cybersecurity policies. The competition not only harnesses the power of quantum technology, but also protects against the threats it poses in relation to the cybersecurity landscape.
