Obsession with RSA encryption and Quantum Computers
Introduction
Quantum computers are a type of computer that uses quantum mechanics to process information. This means that they are able to do things that traditional computers can’t do. One of these things is solving problems quickly; in fact, it is believed that most encryption algorithms will become obsolete within the next couple of years due to advances in quantum computing technology. In this post, I will explain what an RSA encryption algorithm is and why it’s so important for companies and governments alike!
Quantum computers are a type of computer that uses quantum mechanics to process information.
Quantum computers are a type of computer that uses quantum mechanics to process information. They’re faster than classical computers and more powerful, but they can’t solve problems that classical computers can’t solve.
What does this mean? Well, imagine you have a problem in which you need to find the shortest distance between two points on a map. The algorithm you would use on a classical computer would be like this: start with your first point (A), then add one meter to each side until you get to the second point (B). Next, subtract four meters from each side until we reach our third point ©. Finally, take away two meters again until we get back where we started! This method works well for most problems — but not all! If there weren’t any edges or corners involved then this algorithm would work perfectly fine…but if there were any obstacles along those lines then things could get messy fast!
What is an RSA Encryption Algorithm?
RSA encryption is a type of public key cryptography. It’s also called asymmetric encryption because it uses two keys: one public key and one private key. The public key can be distributed freely while the private key must be kept secret.
When you encrypt data using an RSA algorithm, you use your own private key to create an encrypted message that only you can read. You then send this encrypted message over the Internet or other networked devices so that only those who have access to your shared secret know what it says — it may look like gibberish but actually means something important!
Real-world usage of RSA Encryption
RSA encryption is used to secure email, banking, and other online transactions. It’s also used to secure websites and other internet services, including those that run on mobile devices.
RSA encryption is used to secure data on laptops, so you won’t have to worry about your laptop being hacked while you’re out in public or at work.
Why is it impossible to crack RSA encryption?
RSA encryption is based on the Diffie-Hellman key exchange algorithm. The Diffie-Hellman algorithm was developed in 1977 by Whitfield Diffie and Martin Hellman, who were graduate students at Stanford University at that time. The concept behind RSA encryption is that it uses large numbers called prime numbers as keys (in this case, two primes). These primes are combined together to generate a shared secret algorithm that can be used to encrypt messages between two parties who share these secret algorithms with one another but do not know them ahead of time.
The difficulty of factoring large numbers has been known since at least 1770 when Pierre de Fermat claimed he had proved there are no solutions for factoring into an integer times itself, without using any square root operations or continued fractions; however, this remains unsolved today despite many attempts being made over many years. This means if someone wanted access to your private key then all they would need to do is factor it into its constituent parts and then reverse engineer out how much energy would have been spent doing so — making cracking even harder than brute force!
What is a Quantum Computer?
A quantum computer is a computer that uses quantum mechanics to process information.
A classical computer uses the principles of classical physics to solve problems; for example, it can be used to find the answer to an equation or perform calculations like adding two numbers together. Quantum computers use these same principles but they do so in a way that allows them to solve problems much faster than traditional classical computers.
How Peter Shor’s Algorithm Dooms RSA Encryption to Failure
Peter Shor’s Algorithm Dooms RSA Encryption to Failure
The fact that quantum computers can break the encryption algorithms used to secure the majority of data today is a big problem. However, there is some good news for RSA users: Peter Shor has proposed an alternative method that does not rely on factoring large numbers at all! In order to understand how this works, let’s take a look at how RSA encryption works.
RSA uses public key cryptography and relies on both parties having different keys (each with its own private key). The private key is kept secret by one party while it’s shared among many people by using an encryption algorithm called “computation” or “software.” This means that if one person owns your private key, then anyone could decrypt messages sent through them (and vice versa).
In this case, it is more important for companies and governments to focus on methods other than RSA encryption for securing their data.
In this case, it is more important for companies and governments to focus on methods other than RSA encryption for securing their data.
RSA encryption is not safe, not secure, and not quantum proof. It cannot be used to store encrypted data because its implementation relies on a small number of prime numbers (the so-called modulus) that are easy to factorize into their constituent primes.
In short: If you use RSA in your security protocol then there’s a good chance your keys will be compromised or broken by an attacker with enough computational power (and time).
New Quantum Safe encryption in the next 5 years
New Quantum Safe encryption will be introduced shortly. Quantum Computers will be mainstream soon.
Conclusion
In light of the recent findings in quantum computing, we’re going to see a lot more products that use RSA encryption becoming obsolete. This will not just affect the financial industry but also other sectors such as technology and entertainment. The implications for governments are also huge because they would have to find another way to secure their data. Some argue that it will be easier than others since everyone has different needs when it comes down to securing their data
