When this era of quantum computing arrives, we will reach the point where post-quantum cryptography (PCQ) becomes essential.

The RSA algorithm is a feast of genius that combines theoretical math and practical coding into working asymmetric cryptography. Here’s how it works.

For example, this is used to support online shopping or secure messaging, traditionally using the RSA algorithm, though increasingly an alternative called elliptic curve Diffie-Hellman.

Behind the hype lies a grounded, strategic reality: transitioning to post-quantum cryptography is about preparation, not ...

The research team, led by Wang Chao from Shanghai University, found that D-Wave’s quantum computers can optimize problem-solving in a way that makes it possible to attack encryption methods such ...

Ronald Rivest helped come up with the RSA algorithm, which safeguards online commerce. Now he’s hoping to make democratic elections more trustworthy.

RSA Security Inc. unexpectedly released the widely used RSA public-key encryption algorithm into the public domain ahead of this week's expiration of the patent on the algorithm -- a move that's ...

Just as RSA encryption relies on the difficulty of factoring extremely large numbers, three of the four algorithms unveiled this week use a complicated mathematical problem that’s expected to be ...

Quantum computing might have more significant impact on public-key cryptography, which is used to set up secure connections online. For example, this is used to support online shopping or secure ...
