Quantum Computing: Safeguarding Data in the Quantum Computing Era

Jakarta, INTI - In the coming years, the development of quantum technology is predicted to bring significant changes to the cybersecurity and data processing industries. One of the strategic trends identified by Gartner for 2025 is "Post-Quantum Cryptography" (PQC). This technology is considered crucial because it is projected to protect data from the threats posed by the power of quantum computing.

Why Post-Quantum Cryptography?

With the capability to perform calculations far faster than classical computers, quantum computing has the potential to threaten the encryption algorithms currently used across various sectors, including banking, government, and technology firms. In this era, much of the encryption in use may become ineffective due to the sophistication of quantum computers that can decrypt data quickly.

According to recent research, within the next 10-15 years, quantum computers will likely have the capacity to compromise the security of a vast amount of data stored with conventional encryption. Gartner highlights that this trend should be addressed with PQC, which allows encryption algorithms to withstand quantum computing threats.

Business Benefits of PQC

The application of post-quantum cryptography offers numerous advantages, especially for business sectors heavily reliant on the protection of customer data and confidential information. With PQC adoption, businesses can ensure long-term security for their sensitive data, ultimately strengthening customer trust in their digital services.

For example, in the banking industry, where transaction data and customer information are highly protected, PQC implementation can be a sustainable solution to safeguard data from future cyber threats. A report published in 2024 stated that global losses due to cybercrime reached over $6 trillion, and this trend continues to rise. By implementing PQC, the banking industry can reduce the risk of data breaches and create a more secure transaction environment.

Challenges in Implementing PQC

Despite its many advantages, PQC does not come without challenges. One primary obstacle is compatibility. PQC algorithms are not simply drop-in replacements for current asymmetric algorithms. Some applications that use asymmetric algorithms may face performance issues and may require retesting or even rewriting to accommodate PQC encryption.

Additionally, the cost of implementing PQC is relatively high, especially for companies that have recently migrated their security systems or lack the necessary infrastructure. Changing algorithms also requires time and cybersecurity experts who can effectively manage this technology.

Steps Towards PQC Adoption

As quantum computing threats increase, some global tech companies have begun taking steps toward PQC implementation. In 2023, tech giants like Google and IBM, who heavily invest in quantum computing development, started developing tools and platforms that support PQC. For instance, IBM has launched a cloud-based quantum platform that allows researchers to test PQC algorithms at scale. Meanwhile, Google is collaborating with several security institutions to create PQC standards that can be globally adopted.

For organizations and companies looking to begin adopting PQC, Gartner recommends starting by assessing the quantum risks to their stored data. The first steps include identifying sensitive information and current encryption methods, then planning a gradual migration to PQC. Some cybersecurity companies also offer consulting services to help organizations understand how PQC can be integrated into their security strategies.

Future Implications of Post-Quantum Cryptography

PQC implementation is crucial not only for protecting current data but also for future security. Given the rapid advancement of quantum computing, many experts advise companies not to delay adopting PQC, especially those in high-security-risk sectors like finance, energy, and healthcare.

Over the next five years, more companies are expected to invest in PQC technology to anticipate a future that is increasingly digital and vulnerable to quantum threats. A study by the International Data Corporation (IDC) estimates that the global market for PQC-based cybersecurity will reach over $2 billion by 2027, reflecting increased awareness and the need for stronger data protection.

Post-Quantum Cryptography is a strategic solution expected to play an essential role in protecting data from the threats posed by future technologies. With broader PQC adoption, industries and governments are anticipated to create a digital environment that is more secure and prepared to face the challenges of the quantum era.
