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.

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.

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.

Despite RSA's gesture, several competitors who have paid royalties for use of the algorithm for up to 17 years, argue that the industry could have done with the patent relaxation earlier.

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.” ...

The RSA algorithm has become an encryption standard for many e-commerce security applications. The patent for it was issued to MIT on Sept. 20, 1983, and licensed exclusively to RSA Security.

RSA’s demise from quantum attacks is very much exaggerated, expert says Expert says the focus on quantum attacks may distract us from more immediate threats. Dan Goodin – Jan 25, 2023 5:15 PM | 64 ...

Based on the data they collected, they concluded “1,024-bit RSA provides 99.8% security at best.” BACKGROUND: Crypto experts analyze millions of X.509 certificates, call RSA crypto flawed ...
