Bitcoin: Safety from quantum attacks [duplicate]

Title: Safety from quantum attacks: reduction of the risks of encryption in a world according to the section

Introduction

The increase in the quantum computer has sent shock waves in the world of encryption, with potential effects on safe communication and on the archive of data. In this article, we will examine the growing concerns that quantum computers can break some types of encryption, including those used to protect bitcoin transactions.

The quantum threat

Quantum computers have the potential to exponentially increase their performance in a few years. According to experts, it will only take 40 years before a quantum computer can take into account large numbers, which is currently taking many types of encryption. This has a significant impact on secure communication and data archive.

One of the most popular areas of encryption is RSA, which is often used to guarantee online transactions, including Bitcoin. However, it is based on the difficulty of taking into account large numbers, an activity that can be carried out by a quantum computer with a minimum calculation effort.

The problem: quantity of encryption -ofrice

Quantum computers can break a certain type of encryption, included:

• RSA : As already mentioned, RSA is based on the difficulty of taking into account large numbers, which is susceptible to quantum attacks.

2

• AES : Cryptography (advanced encryption standard), which is often used for the storage of safe data, can also be interrupted by a sufficiently powerful quantum computer.

The role of bitcoin in quantum threat

Bitcoin is one of the most frequently exchanged cryptocurrencies with over 18 million users registered all over the world. Therefore, it has a significant impact on the safety of bitcoin transactions.

In 2021, researchers showed that a group of three high -performance quantum computers could break RSA encryption in only 2 hours and decipher Bitcoin transactions. This was achieved using the weak points in the underlying code of the Bitcoin protocol.

MASTIVE THE RISKS

While it is difficult to completely eliminate the risk of quantum attacks on the safety of the cryptocurrency, it is possible to adopt different steps to relieve the effects:

• Gradual introduction : implement and make sure that the gradual introduction of quantum resistant encryption and make sure that all transactions are encrypted with safe protocols, help to reduce damage.

• Cryptography Post-Quantum (PQC) : Development and supply of PQC standards, such as.

• Safe coding practices

  : developers can improve the safety of the code using safe coding practices, e.g. B. The use of safe algorithms and the use of the use of uncertain cryptographic primitives.

• quantity -resistance proof –: the creation of networks of quantity -safe requires considerable systems in the infrastructure, including quantum resistant exchanges exchange protocols.

Diploma

The potential risks of quantum attacks on the security of cryptocurrency are real, but the reduction of these threats requires a multifaceted approach. By understanding the weaknesses of the current encryption and the implementation gradually introduction and post-quentum solutions, we can reduce the risk of catastrophic attack on Bitcoin transactions. Since the world of encryption is developing in response to emerging technologies such as quantum calculation, it is important to give priority to security and innovation to protect our most precious resources: our data.
