I am searching the recommended cryptographic key sizes for securing
I found some recommendations in the next reference: B. Kaliski. TWIRL
and RSA Key Size. RSA Laboratories. Revised May 2003. Online at
In this technical note RSA recommends 1024-bit public keys and 80 bit
(AES) symmetric key till the year 2010 for equivalent security
level(See Table 1).
My questions are:
- Which organizations are globally recognized/accepted to set the
recommended cryptographic key sizes? Links?
- Can you provide any recommendations on cryptographic key sizes based
on personal experience/knowledge/expertise?
Your answers are certainly appreciated.
