Virtually every industry in the world today relies on encryption (the process of converting readable data into scrambled, unreadable data so that only someone with the correct key can decode and access it) to protect sensitive information. Banks, telecommunications providers, defense organizations, and practically everyone else are using some form of encryption - most probably AES (Advanced Encryption Standard). Decrypting the protected data without the encryption key is considered almost impossible, since the computational
effort necessary to pull it off would simply be too large. However, since quantum computers work on a fundamentally different principle, it is believed that once they are mature enough, they will be able to crack todays
encryption standards. Latest Videos From TechRadar Watch full video here:
G7's advice Now, the G7 has urged government and organizations to remain
ahead of the curve by deploying quantum-resistant encryption:

To protect themselves from the threat brought by CRQCs (cryptographically relevant quantum computers), organizations should begin planning their PQC transition now and should aim to complete their transitions within any the timelines set out by their national cybersecurity authorities, the warning reads.

In addition to quantum-related risks, organizations that delay their PQC transition may lose competitive advantage or may be excluded from contracting opportunities, including public procurement.

The G7 advises governments and organizations to take a number of steps, including identifying critical systems and prioritizing them. They should adopt a phased and risk-based strategy, start their transition early, and inventory their cryptographic assets. They should also map their dependencies and develop a transition plan.

To limit transition-related costs, they should opt to purchase products that integrate PQC and replace their systems with quantum-safe ones as part of their standard renewal schedule. As such, starting the transition early could result in lower migration costs overall. Planning and conducting their PQC transition properly would enable organizations to prevent insecure implementations and avoid increased exposure to conventional cyber threats.
