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.

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.

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.” ...

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.
