Quantum hacking is the biggest threat to encryption.
Quantum computers have limitless potentials. There is no doubt that one day quantum computers will find a cure for cancer or help in eliminating world hunger. But along with this, they could also help hackers get access to our most private data by breaking encryption. While quantum computing is beneficial, quantum hacking is dangerous.
What is quantum hacking?
To be precise quantum hacking is the use of quantum computers to carry out malicious actions. Quantum hacking is performed by modern cryptographic strategies which often use private and public keys to encrypt and decrypt data through a mathematical equation. These mathematical equations can be easily broken by advanced quantum computers. It would surely take a while, but the process is still possible using the nonlinear protocol of quantum computing.
When quantum hacking becomes possible, a system that repairs the existing internet security practices needs to be developed. If not, it would be easy for hackers to break through data and cause costly issues.
Threat to Encryption
With digital transformation, everything is now digital, even data, and all our digital data like emails, chats, online purchases, etc are encrypted which makes it unreadable without a decryption key. This prevents our data in the cloud and our computers from being tampered with. AES (Advanced Encryption Standard) is the most commonly used method for encrypting all this data. With today’s classical computers it is impossible to break AES encryption, but through quantum computers, it is possible to decrypt the encrypted data.
It is believed that quantum-optimized algorithms and artificial intelligence will increasingly be used together in breaking the mathematically based cryptographic algorithms. While performing a huge superposition of possible results to these algorithms requires a quantum device in the millions of qubits and the largest quantum computer today has just 72 qubits, similar results can be obtained with quantum-optimized algorithms performing within a computer emulator running on consumer gaming video cards.
