‘Harvesting Attacks’ & the Quantum Revolution

Remember, just because your data can’t be decrypted today it doesn’t mean that it’s safe forever…:

[…] Alongside these benefits is a danger from quantum computing that most people don’t realize is here, now, even though the quantum computers aren’t ready yet. This is because encrypted information stolen by China from the US government and industry is being stockpiled by China. Cheap data storage and the proliferation of valuable data online increases the feasibility and incentive for long-term storage of even the most solidly encrypted data. This offensive strategy is known as a harvesting attack. Encryption protects everything from classified data to the operations of power plants, water supplies, and financial trading systems. Once quantum computers are available, not only will the most critical data be exposed, but quantum-powered attacks will be able to interfere with important cyber-controlled processes as well. Cloaked secrets will be revealed and physical equipment will be manipulated remotely.

We Need to Get Moving
It may be too late for much of the data that’s already been intercepted, but we can work to protect more of our data going forward — but only if the government takes this threat seriously.

The National Quantum Initiative Act (NQIA), which was signed into law in December, commits $1.2 billion to fund quantum science and computing efforts over five years to be divided between the National Institute of Standards and Technology (NIST), the Department of Energy (DoE), and the National Science Foundation. None of the money has yet been appropriated. Meanwhile, China is building a $10 billion quantum research lab that is slated to open next year.
