What Will Happen to Encryption When Quantum Computers Arrive?

Encryption protects sensitive information such as passwords, financial transactions, and personal messages. Current encryption methods are based on complex mathematical problems that are hard to solve by conventional computers. This makes it virtually impossible for hackers to break into encrypted systems.

However, quantum computers could change this. Quantum computers use quantum mechanics to process information. This allows them to solve certain types of problems much faster than today’s technology. One of the problems they excel at solving is breaking encryption.

How Encryption Works Today

Today, encryption depends on mathematical algorithms. Popular techniques include RSA and ECC (Elliptic Curve Cryptography). Each of these techniques creates the keys used for data encryption and decryption.

The strength of a key is generally determined by the difficulty in solving some type of problem in mathematics, such as factoring large numbers or computing discrete logarithms.

Quantum Computers Will Make For A Very Different Encryption

Quantum computers can calculate various outcomes simultaneously. They are able to find complex mathematical solutions much quicker than older conventional computers.

On the one hand, it is going to be a much more profound disruption in quantum computing when Shor’s algorithm can factor large numbers within a few minutes. This will directly impact both RSA and ECC encryption.

This means that, as soon as Shor’s algorithm gets implemented on a quantum computer, most key sizes of these types of encryption will be broken in a matter of minutes.

The Role of Quantum Cybersecurity Companies:

Quantum cybersecurity company works on developing encryption schemes that would be attacked and not by quantum computers. It is commonly referred to as post-quantum cryptography.

These companies may consider developing new algorithms. These are problems that are difficult for both traditional and quantum computers. A quantum cybersecurity company like Qusecure that works on tools that help businesses upgrade their systems to this end and prevent a scenario where sensitive information is exposed when quantum computers become ubiquitous.

These companies also aid organizations in identifying risks. Many businesses have no idea how vulnerable their systems are to future quantum threats. A quantum cybersecurity company can assess these risks and recommend solutions.

What is Post-Quantum Cyber Security?

Post-quantum cyber Security is a system or process that aims at preventing quantum threats. The concept ensures that data are secure even when quantum computers get strong enough to destroy the current encryption.

Why Act Now?

Quantum computers are unavailable to the majority. But experts also say they are not so far away. Some research laboratories are already working with quantum computers.

While it would be years before quantum computers start to be commonplace, the danger is very real. That’s because hackers could start stealing the encrypted data today in an attempt to decrypt it using a quantum computer when available.

Companies dealing with sensitive information, like banks or health facilities, are highly at risk and have to ensure that their systems are future-proof.

Quantum cybersecurity firms provide the means to make this transformation possible. These organizations are thus developing solutions not for any current problem, but for something far into the future of data security.

How to Prepare for the Quantum Future

Businesses and governments must take numerous actions to prepare. First, grasp the risks. Quantum threats to cybersecurity are not theoretical. They will pose a problem that requires immediate attention.

Organizations must also interact with subject matter specialists. A Quantum cybersecurity company has the knowledge and capabilities to help businesses shift to quantum-safe systems.

This involves replacing insecure encryption techniques with quantum-safe algorithms.

And finally above all, education and awareness. Decision-makers must also be trained and made aware of the current state of quantum computing so that they can realize the necessity of deploying post-quantum encryption.

QuSecure’s Role

QuSecure, quantum cybersecurity company, markets its offering as a complete suite for all organizations wanting to protect their data from the threats of tomorrow’s quantum attacks. All of the technologies will be for building quantum-safe encryption solutions and also support organizations.

QuSecure educates organizations about the quantum attack threat. This organization will prepare the businesses for challenges to come.

Pre-protect any data before quantum computer availability.
