The future of quantum computing is not far off; in fact, it is coming closer than ever. This cutting-edge technology has many potential advantages, but it also carries a number of serious hazards, especially for our digital world’s security. This blog post will explore **how the internet might be compromised by quantum computers**, drastically changing the field of cybersecurity and encryption.

**Y2Q Will Happen. How Does It Signify?**

“Years to Quantum,” or “Y2Q,” is the estimated amount of time it will take for **quantum computers** to mature and become strong enough to defeat existing cryptography. Many experts foresee substantial breakthroughs as early as 2025, but others believe this will happen within the following ten years. This timeline emphasizes how urgent it is to switch to quantum-resistant cryptography standards and get ready for the quantum future.

**Workings of Public-Key Cryptography**

The foundation of safe internet communications is public-key cryptography. Key pairs—a publicly available public key and a private, encrypted key—are its foundation. Messages are encrypted and decrypted using these keys, guaranteeing that only the intended receiver may read them. Cryptography algorithms such as RSA (Rivest-Shamir-Adleman) and ECC (Elliptic Curve Cryptography) rely on mathematical problems that are not currently solvable by traditional computers in an acceptable amount of time. For example, a traditional computer would take over 300 trillion years to crack the data security algorithm RSA-2048.

**Reasons for Concerning Public-Key Cryptography with Quantum Computers**

Rather than using classical bits, **quantum computers use qubits**, which are based on the concepts of quantum mechanics. Because qubits can be entangled and exist in numerous states simultaneously (superposition), they enable quantum computers to do complicated calculations far more quickly than traditional computers. The 1994 algorithm Shor’s proves that a quantum computer may effectively solve the factoring problem, on which RSA is based. In other words, RSA-2048 might potentially be cracked in a few hours by quantum computers.

**How Can Quantum Computers Decipher Cryptography?**

**Quantum computers** use their processing capability to solve mathematical puzzles that underlie cryptographic systems, which allows them to break encryption. If a quantum computer was powerful enough, it could factor enormous numbers used in RSA in hours or even minutes, but classical computers would need millennia. It is possible for a quantum computer with 4096 qubits to factor a 2048-bit RSA key in less than a day, whereas a classical computer would require billions of years to complete the task.

**How Quickly Can a Quantum Computer Decrypt Data?**

A quantum computer’s error rate and qubit count determine how quickly it can decrypt data. A quantum computer with a few thousand logical qubits might crack RSA-2048 in a matter of hours, according to current estimations, but a classical computer would need billions of years to do it. Google’s study indicates that a calculation that would have taken the world’s fastest supercomputer, Summit, 10,000 years to complete was performed in 200 seconds using their 53-qubit quantum computer, Sycamore.

**Does AES-256 Break Under Quantum Computing?**

Comparing symmetric encryption techniques like AES-256 versus asymmetric ones, the former is thought to be more resilient against quantum attacks. It is theoretically possible for Grover’s technique to shorten the effective key length, bringing the strength of AES-256 to that of AES-128. Accordingly, a **quantum computer** would need a lot less time than a conventional computer to crack AES-256, even though it is still very secure. According to current estimates, cracking AES-256 using Grover’s technique would take about 2^128 quantum operations, which is still a very difficult undertaking.

**Could Passwords Be Broken by Quantum Computers?**

Hashed passwords are also vulnerable to quantum computing. Quantum computers may be able to reverse-engineer hash functions and crack passwords far more quickly than with traditional techniques by taking advantage of their capacity for parallel computing. A quantum computer, for instance, may search through a list of possible passwords in √N time, where N is the total number of passwords, by applying Grover’s algorithm. Thus, a password that would take a year to crack on a conventional computer may be cracked in roughly six months on a quantum computer.

**Does Bitcoin Resist Quantum Crystallization?**

The security of Bitcoin is based on cryptographic concepts such digital signatures using the Elliptic Curve Digital Signature Algorithm (ECDSA) and hashing using SHA-256. The integrity of the blockchain might be jeopardized if a **quantum computer** were able to reverse the hashing procedure or crack the elliptic curve encryption. Bitcoin’s elliptic curve cryptography is currently unbreakable with current technology; it would require a quantum computer with 1500 logical qubits.

**Can TLS be Broken by Quantum Computers?**

Additionally dependent on public-key cryptography are the Transport Layer Security (TLS) protocols that safeguard internet connections. These communications could be decrypted by **quantum computers**, giving attackers access to them. In TLS 1.2, for example, key exchanges using RSA or DH (Diffie-Hellman) are susceptible to quantum attacks. Quantum-resistant algorithms have been introduced into the more recent TLS 1.3, however mainstream implementation is still pending.

**New Techniques Could Preserve Our Privacy**

The objective of post-quantum cryptography is to develop algorithms that are impervious to quantum attacks. These include lattice-based, hash-based, and code-based cryptography methods. For instance, the National Institute of Standards and Technology, or NIST, is actively reviewing potential standardization candidates. The Learning With Errors (LWE) problem exemplifies a promising lattice-based cryptography technique that is thought to be impervious to both classical and quantum attacks.

**A Quantum Internet Might Boost Safety**

Unprecedented security may be possible with a **quantum internet that uses quantum** key distribution (QKD). Theoretically, QKD generates keys that are impossible to intercept covertly by utilizing the laws of quantum physics. The Micius satellite in China and the Quantum Network in Beijing are two examples of real-world implementations that have proven QKD is feasible over extended distances and opened the door to more secure communications.

**How Does Cryptography See Itself in the Future?**

**Quantum computers** are not a cure-all, despite their potential. They are not always better than traditional computers; they are better at some kinds of issues. Extensive memory or tasks requiring accurate, error-free calculations may still benefit from traditional approaches. On classical systems, for instance, large-scale data storage and simple arithmetic operations continue to be more efficient.

**Can AES be broken by quantum computing?**

Even in the face of quantum concerns, AES-256 is still a reliable encryption technology. Even if quantum computing has the potential to compromise security, AES-256 still provides a high level of protection, particularly when paired with post-quantum cryptography techniques. According to research, strong security in a post-quantum environment can be achieved by combining AES-256 with quantum-resistant algorithms.

**Is AI Able to Crack RSA?**

Artificial intelligence has a less impact on RSA encryption cracking than quantum computing. The processing power needed to crack RSA is beyond the capability of contemporary AI, despite the fact that AI can help with cryptographic analysis. On the other hand, AI can be utilized to enhance attack plans and boost the effectiveness of quantum algorithms.

**Could AI Beat Captcha?**

When it comes to resolving CAPTCHA puzzles, AI has advanced significantly and is frequently more accurate than humans. This makes it necessary to create more advanced CAPTCHA systems or find other ways to distinguish between humans and bots. According to a 2019 study, 94% of powerful AI systems could successfully evade Google’s captcha v3.

**Is AI Able to Prevent Crime?**

AI is being utilized more and more in law enforcement to do jobs like data processing, facial recognition, and predictive policing.
