A recent research paper makes the claim that the RSA cryptographic algorithm can be broken with a quantum algorithm. Skeptics warn: don’t believe everything you read.

PKI algorithms like RSA and elliptic curve cryptography (ECC) use “trapdoor” math problems that are easy to solve in one direction but immensely difficult to calculate in reverse.

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

Some cryptographers are looking for RSA replacements because the algorithm is just one encryption algorithm that may be vulnerable to new machines that exploit quantum effects in electronics.

Shor’s algorithm poses a risk to public-key encryption systems such as RSA, whose mathematical defenses rely in part on how difficult it is to reverse-engineer the result of multiplying very ...

A toy RSA algorithm The RSA algorithm is the most popular and best understood public key cryptography system. Its security relies on the fact that factoring is slow and multiplication is fast.

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 ...
