NEW! TWIRL and RSA Key Size
The popular 1024-bit key size for RSA keys is becoming the next horizon
for researchers in integer factorization, as demonstrated by the innovative
“TWIRL” design recently proposed by Adi Shamir and Eran Tromer.
The design confirms that the traditional assumption that a 1024-bit RSA
key provides comparable strength to an 80-bit symmetric key has been a
reasonable one. Thus, if the 80-bit security level is appropriate for
a given application, then TWIRL itself has no immediate effect. Many details
remain to be worked out, however, and the cost estimates are inconclusive.
TWIRL provides an opportunity for review of key sizes in practice.
