Secure messaging platformSignalhas announced commitments to keep users safe against quantum-level attacks, beginning with an upgrade to its protocol to protect its end-to-end encryption further.

In anupdate, Signal CTO Ehren Kret said the “layer of protection” would protect “against the threat of a quantum computer being built in the future that is powerful enough to break current encryption standards.”

Quantum computing promises to pose a very real threat to encryption in the future, and Signal’s commitment to build in quantum-level protection is a testament to its focus on security.

Signal has grown in popularity in recent years amid concerns over less secure messaging services thanks to its end-to-end encryption, which promises to keep unwanted eyes out of personal messages.

It’s also a firm favorite among those concerned about cybersecurity and their digital footprints as it is a standalone product -WhatsApp, for example, forms part of the much larger Meta portfolio.

While quantum computing is far from a global reality, it does pose the very real threat of solving problems much more quickly than classical computing, meaning it could crack encryption keys in a comparably short space of time.

Kret added: “Although quantum computers already exist, the systems known to exist today do not yet have enough qubits to pose a threat to the public-key cryptography that Signal currently uses.”

It’s unclear how far away powerful quantum computers could be, but Signal does at least see them as a “real and growing risk,” hence the early preparation.

Post-quantum cryptography continues to be an area that requires huge amounts of work, but Signal has certainly earned itself even more trust among fans as concerns about digitalprivacycontinue.
