Post-Quantum Cryptography Urged Amid Encryption Threat
Quantum computing may break current encryption. Experts urge quick adoption of post-quantum cryptography to protect future data.
- Quantum tech may crack today’s encryption
- “Harvest now, decrypt later” poses real risk
- Shift to post-quantum cryptography is urgent
Quantum Computing Could Break Today’s Encryption
In a stark warning, cybersecurity researcher Gianluca Di Bella has raised alarms about the growing threat quantum computing poses to modern encryption systems. The current cryptographic standards that secure everything from financial transactions to private messages could soon be rendered obsolete by quantum breakthroughs.
Quantum computers, unlike traditional machines, use qubits that can process exponentially more data — potentially allowing them to break encryption algorithms like RSA and ECC in a matter of minutes. This emerging threat has led to increased concern over the security of sensitive data in both public and private sectors.
“Harvest Now, Decrypt Later” Attacks Already Happening
One of the most concerning aspects raised by Di Bella is the strategy known as “harvest now, decrypt later.” In this method, attackers collect encrypted data today — knowing they can’t crack it yet — and store it until quantum computers become powerful enough to decrypt it instantly. This means data that seems secure now could be compromised in the near future.
This looming vulnerability places critical data — such as state secrets, banking details, and personal information — at serious risk. The timeline for practical quantum computing is narrowing, and the clock is ticking for encryption to evolve.
Post-Quantum Cryptography Is the Solution — But Are We Ready?
The answer lies in post-quantum cryptography, a new class of encryption algorithms specifically designed to withstand quantum attacks. Several of these algorithms are already being tested and standardized by organizations like NIST.
However, adoption is moving slowly. Legacy systems, outdated infrastructure, and lack of awareness hinder the shift. Di Bella and other experts warn that unless governments and tech industries move quickly, we may be left unprotected at a crucial moment.
The crypto and blockchain world, which heavily depends on strong encryption, must also prepare for this shift. Projects working on quantum-resistant blockchains may soon become essential.
