My intuition tells me it's a trade off between speed and security, but how did the standardisation process select these three seemingly arbitrary key lengths (namely, AES-128, AES-192, AES-256).
Multi-prime RSA is now a well known technique: it uses $k>2$ distinct secret prime factors in the public RSA modulus, with the advantage that, using the CRT, we can gain a speed boost in ...
Is it true, that non-military cryptography appeared in 50's and 60's only thanks to leaks from the NSA? [closed]
I'm not talking about scytale, but encryption like RSA, DES, etc... How did exactly civil cryptography evolve after WWII?
