How Quantum Computing Will Change Encryption Forever

 However, every now and then an emerging technology changes the way we do things, requiring urgent action, usually from both sides. For instance, cloud computing has changed the way businesses deal with cybersecurity, a transition which many companies are exploring.

Quantum computing has the capability to transform how we interact with computers and technology , providing us with a huge computing capacity. But, if it's misused when it's misused this could mean quantum computing could also cause harm to our security. When we're unprepared, companies are at risk like never before.

Quantum computing is an important paradigm shift which we must address in the earliest possible time, before hackers can gain access to the technology.

Quantum computing promises to be the future of computing

Quantum computing was under development in the past few years and is based on the basis of quantum mechanics. The traditional computing system has depended on the binary system that relied on 0s and 1 Quantum computing is driven by quantum mechanics instead of relying on a binary platform, it operates a Qubit system which can possess quantum properties, such as being simultaneously zero or1.

Without getting into the technical details that are being researched and developed quantum computing is far superior to classical computing, which is the type of computing we can access in the present even by supercomputer standards.

Computing power is typically determined by its capacity to handle data, and to solve complex mathematical problems. Quantum computers are capable of processing data and solve mathematical issues in fractions of the time it'd require a conventional or supercomputer.

This is a huge opportunity in the fields of medical research as well as finance, AI and cryptography. For instance, Goldman Sachs and QC Ware are making quantum computing as service accessible in five to 10 years time and promising a 1000x boost in mathematical calculations used for financial decision-making. However, it may alter some of the cybersecurity technologies that we currently use and, if placed into the hands of malicious people, could destroy the basis of our security systems that we use throughout the web.

Traditional encryption could be removed from use by the use of QC

We rely on encryption each and every each day, whether we realize whether or not. It is essentially a way to hide information behind mathematical issues that are too complex for a normal computer to resolve. Encrypting data is almost impossible, or could take thousands, if not hundreds of years, effectively keeping it inaccessible.

We employ encryption in order to protect our day-to- daily activities from being viewed by snoopers through HTTPS which is slowly making its way across the majority of websites. End-to-end encryption is also used to ensure that conversations are safe in apps such as Signal or WhatsApp. The companies also use encryption to ensure their data is secure even in the event that they lose it through a breach of data leak or accidental exposure.

This could stop hackers from gaining access to, selling or leaked data even if the hacker succeeded in gaining access to an organization and smuggled out the information.

Quantum computing could be used to undermine the basis for the current encryption standards. If we consider the previous scenario, a hacker that succeeds in stealing encrypted data from a business would not have any difficulty in decrypting the data if they were able to access quantum computing technology.

Quantum computing might not be available to everyone -- but well-funded state-sponsored hackers and hacker organizations could be the first to obtain one. We saw this with the growth of Ransomware as a Service (RaaS) -- it could suffice for one company to be able of using quantum computing to grant access to other hackers, but who would normally not have the resources or funds.

Standards for encryption must be upgraded completely

Although this scenario of nightmares is quite real, we have the time to prepare. Quantum computing will not be accessible for another decade or two as technology continues develop. Researchers have time to come up with new encryption methods and standards as well as allowing companies to apply these standards appropriately.

But, researchers face quite the task to complete. They must develop the latest encryption methods that are protected against quantum computing, but created with traditional hardware. It's already a difficult fight that must be resolved sooner rather than later, as time passes for a post quantum secure encryption technique to be made available in the long run, the longer it will take for these standards to be adopted and implemented across all businesses and the internet at large.

For instance, HTTPS, which is an encrypted version of HTTP and is much more secure, had a 50% of the websites in 2016 as per Google's analysis of traffic (Google assessed the number of HTTP as compared to HTTPS websites using Chrome). By 2021, the percentage has increased to 95 percent.

It's difficult to predict what the quantum secure encryption postquantum implementation is going to progress however the longer we can wait to work with it, the more efficient. It is preferential to be proactive with these encryption techniques implemented by the time quantum computing is used for malicious attacks.

NIST recently revealed new post-quantum secure algorithm

We're fortunate to have taken a important step to combat this threat. NIST has recently chosen four algorithms that are deemed post-quantum safe and will be included in the post-quantum cryptographic standard, which is expected to be published within the next two years.

In the past few times, Bitdefender researchers worked on research issues related to security foundations for the lattice-based ideas that were presented to NIST.

The algorithms are designed to strengthen and reinforce the encryption that forms the security base that protects TLS as an fundamental encryption protocol used throughout the majority of internet-based communications. These algorithms were also designed to be used in the creation of digital signatures, which verify identity and facilitates signing documents online.

The algorithms used are based on classical computing , and were designed using traditional hardware, which means they can be utilized with the modern computers and will be safe even in the face of quantum computing. This is a significant step toward becoming post-quantum safe and is a key aspect of security in networks for both individuals and businesses.

The encryption standards we currently have are sufficient , however with quantum computing being on the horizon and the need for an upgrade, it's time to get one. In the meantime, as NIST continues to work on developing and makes their final decisions regarding the algorithms it recommends, security researchers as well as IT departments should begin making plans for the implementation of the new cryptographic standards.
