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.

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.

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 ...

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.

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.

The first public key encryption algorithm: RSA The first algorithms using asymmetric keys were devised in secret by the British government's SIGINT agency, GCHQ, in 1973.

Computing How a quantum computer could break 2048-bit RSA encryption in 8 hours A new study shows that quantum technology will catch up with today’s encryption standards much sooner than expected.
