    Encryption
In summary, At a scientific conference in Vienna, the launch of the world's first computer network protected by unbreakable quantum encryption has brought us closer to perfect secrecy. However, it must be noted that no encryption can truly be "unbreakable" and this holds by definition. The main benefit of this technology is that it prevents eavesdropping on a single unbroken length of single mode fibre between two points, but it does not protect from a "man in the middle" attack. Ultimately, this is a technology solution to a human problem, and it highlights the need for proper security measures beyond just encryption.

I think this is the perfect place to discuss the possibilities of quantum cryptography. It seems to have become a reality now. Let's discuss whether this truly is unbreakable! We've heard it before, but is it different this time?

Perfect secrecy has come a step closer with the launch of the world's first computer network protected by unbreakable quantum encryption at a scientific conference in Vienna.

No encryption can be "unbreakable."

This holds by definition.

So if someone could break it then that would mean we have to rewrite the science books?

One-time pad? Quantum entanglement?

It's not encryption it's only secure fibre links - this is not new (although the range might be a record)
It does however solve a problem that isn't the problem - it stops you being able to eavesdrop on a fibre by patching into the fibre.
If you have traffic data encrypted with modern algorithms like AES this isn't a problem.
The main drawback is that you can still eavesdrop everytime it goes through a switch or router - this technique only works for a single unbroken length of single mode fibre between two points.

I don't see how this would protect from a "man in the middle" attack either. It seems a lot of effort for little benefit.

It doesn't.

It's the classic security thing - a technology solution to a human problem.
eg. the cleaners found someone's password in the trash: solution double the number of bits in the encryption.
 

1. What is 'Unbreakable' encryption?

'Unbreakable' encryption is a type of encryption that uses highly complex algorithms and techniques to ensure that the encrypted data cannot be deciphered by anyone other than the intended recipient.

2. How is 'Unbreakable' encryption different from other forms of encryption?

'Unbreakable' encryption is considered to be one of the most secure forms of encryption available. It uses cutting-edge techniques and algorithms that are virtually impossible to crack, making it much more difficult for hackers or other malicious actors to access the encrypted data.

3. How does 'Unbreakable' encryption work?

'Unbreakable' encryption works by converting the original data into an unreadable format using complex mathematical algorithms. The encrypted data can then only be deciphered by using a key or password that is known only to the intended recipient.

4. Is 'Unbreakable' encryption truly unbreakable?

While 'Unbreakable' encryption is considered to be highly secure, no form of encryption is completely unbreakable. However, the complexity and strength of the algorithms used in 'Unbreakable' encryption make it extremely difficult and time-consuming to crack.

5. How is 'Unbreakable' encryption beneficial?

'Unbreakable' encryption is beneficial because it provides a high level of security for sensitive data, such as personal information, financial data, and government communications. It helps to protect against cyber attacks and unauthorized access to confidential information.
