Understanding a known-plaintext attack A known-plaintext attack (KPA) occurs when a hacker uses pairs of both encrypted and unencrypted data to figure out the encryption algorithm or key. In this ...

Shanghai University researchers led by Wang Chao claim they used a quantum computer produced by Canada’s D-Wave Systems to breach the algorithms through quantum annealing, which involves ...

Widely used encryption algorithms like RSA and elliptic-curve cryptography (ECC) will be pointless. Depending on who is running the quantum computers, they will turn from superhero to supervillain.

NIST announced three of the four proposed quantum-resistant encryption algorithms this week: CRYSTALS–Kyber, CRYSTALS–Dilithium, and SPHINCS+. The fourth one, FALCON, might be released next year.

RSA and other encryption algorithms have been in use for decades with no known ways for them to be broken. Over the years, that track record has led to confidence that they are safe for use.

Authorities have warned today’s encryption will become vulnerable to hackers when quantum computers are widely available. kacper pempel/Reuters By Catherine Stupp Aug. 13, 2024 6:00 am ET | WSJ Pro ...
