WhatsApp Rolls-Out Emojis and Sharing of Files Over 2GB
Following last month’s announcement, Meta’s WhatsApp is rolling-out emojis and the ability to share files within WhatsApp up to 2GB in size.
In this article, we look at what the ‘quantum apocalypse’ is, and what businesses are doing to prepare for this threat.
The so-called ‘quantum apocalypse’ refers to the unspecified point in the future where someone (e.g., threat actors or a foreign power) has a functioning quantum computer that can break the kind of encryption that we trust to secure our data, transactions, and communications. This vision is apocalyptic because it would mean that this quantum computer could be used to shut down government defence systems, clear bank accounts, clear Bitcoin wallets, create financial chaos, and access all manner data and communications systems. In terms of national, enterprise, and personal security, this scenario (which is a real possibility) could really be apocalyptic and especially for those agencies, businesses, and organisations that have a legal responsibility to hold and store our data.
A Quantum computer can carry out complex calculations at high speed. Whereas traditional computers store data in binary ‘bits’ (ones and zeros) and work by creating and storing long strings of these ‘bits’, quantum computing’s ‘qubits’ (quantum bits) can do both at once. This is because a qubit can hold a zero, a one, or any proportion of both zero and one at the same time, and an array of qubits can use something called ‘superposition’ to represent all 2^64 possible values at the same time. This means that information can be processed much more quickly than with a traditional computer.
The fact that Quantum computers can store so much more data in fewer bits, means that in addition to being able to solve extraordinarily complex problems, they can do so at high speed. Quantum computers can be used, for example, to dramatically speed up tasks that have traditionally taken a long time, such as finding new drug molecules.
The results can be astounding, where crunching numbers that would take a classical computer a week, could take a quantum computer less than a second. For more information (and examples like this), there are some interesting take-aways from IBM at: https://www.ibm.com/quantum-computing/what-is-quantum-computing/ .
The fear is, however, that although the rate of improvement in quantum computing has slowed in recent years, over time they are still likely to become many times faster than today’s machines. This raises the possibility that the world could be caught off guard by someone developing a quantum computer that could render most known methods of encryption useless. This risk has been taken very seriously for several years now. For example:
Having known about this threat for some time, many global businesses in the financial and tech sectors have been taking ‘quantum-proofing’ measures to protect themselves and their stakeholders. Examples of how businesses have been preparing include:
Quantum computers offer so much promise in enabling governments, businesses, and organisations to solve complex problems in a mere fraction of the time that normal computers can. It is a very real risk, however, that this power, in the wrong hands could be weaponised and used to crack the encryption that the world trusts and relies upon. The race is on, therefore, to create powerful algorithms that can stand up to attacks from quantum computers. With grand names like post-quantum cryptography / quantum-proof cryptography, and quantum-safe / quantum-resistant cryptographic (usually public-key) algorithms, these are the next generation of protection for businesses everywhere. Although it seems a long way off, the evidence is that the threat is real and the development of these algorithms and other solutions yet to come are likely to play a vital role in protecting us all from the threat of the so-called ‘quantum apocalypse.’

Apple, Google and Microsoft have announced that they are joining forces to support a common passwordless sign-in standard that will allow websites and apps to offer consistent, secure and easy sign-ins across devices and platforms.
In this article, we look at the legal issues around recording calls on your mobile, and the different methods for doing so.
