RSA is a different algorithm with a longer history and a broader adoption, at least in the past. It depends upon the complexity of factoring large numbers.

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 RSA algorithm works as follows: First, I find two huge (at least 100 digits each!) prime numbers p and q, and then I multiply them together to get the even bigger number N.

And if the latter were able to break RSA, it would’ve already done so.” He concludes: “All told, this is one of the most actively misleading quantum computing papers I’ve seen in 25 years.” ...

One algorithm, a pseudo-random bit generator, Dual_EC_DRBG, was ratified by the National Institute of Standards and Technology (NIST) in 2007 and is attracting a lot of attention for having a ...

Breaching the RSA-2048 algorithm requires, similar to other algorithms in the RSA numbers family, finding the prime factors of a number with 617 decimal digits and 2048 binary digits.

But defenders make life really hard for them by using very long key pairs—like the RSA 2,048-bit implementation, which renders a key that is 617 decimal digits long.

The RSA algorithm works because, when n is sufficiently large, deriving d from a known e and n will be an impractically long calculation — unless we know p, in which case we can use the shortcut.

The U.S. National Security Agency (NSA) paid $10 million to vendor RSA in a “secret” deal to incorporate a deliberately flawed encryption algorithm into widely used security software ...
