Is Quantum Encryption the Future of Cyber-Security?

3rd October 2017

Cyber Security has been a massive concern in 2017. Since the Wannacry Ransomware Attack struck on May 12th, which was one of the largest Ransomware attacks ever recorded, a lot of attention and effort has been directed at ensuring businesses are secure and protected from cyber-attacks.

The problem we all face is that technology is constantly growing, becoming more powerful, getting smarter and more complex and it is changing and moving forward every single day. We come up with a solution to safeguard businesses and their confidential data and the hackers come up with a new technology that gets around the solutions we build. Therefore, it is a constant and ever-changing battle to stay one step ahead of the Cyber Hackers to ensure the security of businesses around the globe.

What is the future of Cyber Security?

The term “unhackable” doesn’t currently exist but thanks to a technological program being developed in China, this term could become a reality. The technology we are referring to is “Quantum Encryption or Quantum Cryptography”.

How does it work?

  • If you want to send your secure message, you first separately send a key embedded in particles of light.
  • Only then do you send your encrypted message and the receiver will be able to read it with the help of the key sent beforehand.

The crucial advantage of this so-called quantum key distribution is that if anyone tries to intercept the light particles, they will alter or destroy them.

What this means is that any attempt at hacking will immediately be noticed by the original sender and the intended receiver – hence its description as “unhackable”.

As computers become more powerful and new and innovative technologies get built, it is undeniable that hackers will use them in their favour and against us. This will result in the current security measures we implement becoming outdated and easily targeted for hack attacks.

Steady improvements in computer power mean that the number-based keys have to be lengthened periodically. Encryption has a shelf life and is rapidly becoming more vulnerable by the day.

There are also fears that the development of quantum computers, which effectively represents a massive change in number crunching abilities, will render much of modern encryption software vulnerable.

No one knows what will happen for certain in the future, but one thing for sure is that Cybersecurity and Cyber-attacks will evolve as new technology is produced. Quantum Encryption could be key to “unhackable” safeguards to ensure that your messages and data are not compromised. Only time will tell to see if this becomes a reality but if it does it could be a huge breakthrough for businesses all around the world.

In the meantime, it is absolutely essential that your business is protected from the current threats that stalk the web looking for vulnerable computers.

How Do I Protect My Business?

Start by reviewing what protection you have in place. Antivirus is no longer enough on its own – you’ll need a layered approach to reduce the chances of infection and becoming a victim of ransomware, malware and virus’s. Also, be aware of zero-day vulnerabilities – attackers can exploit those vulnerabilities for which there are no patches.

Once you’ve completed your security review, start off by taking action in the areas that you have identified as the weakest or have the least protection.

Ransomware threats typically enter your business via malicious email, then download their payload via the internet. Any infection will spread fast, so your response must be equally so. Document your response and store it with your Disaster Recovery & Business Continuity plan.

It’s more important than ever to be vigilant when opening emails – if it looks suspicious, or if you’re unsure, delete it, or send it to your trusted IT Support company for review (we can then take the appropriate action).

Always remember, no ICT system is ever 100% secure, so always be cautious. Regularly review and improve your businesses security and backup solutions.
