Example Questions

votes newest recent

Cryptography: I'm writing a program for hard drive encryption. What cipher modes are a good choice for this application?

Cryptography: Is there a way to combine two or more hashes such that if any one of them is collision resistant the overall construction is also collision resistant?

Cryptography: Under what assumptions is PBKDF2 a pseudo-random function? Do I need to assume the hash is a random oracle? Do any of the HMAC/NMAC proofs apply?

Cryptography: The Skipjack block cipher uses an 8 bit sbox (called F in the spec). Does this permutation have an underlying mathematical structure, or is it random?

Cryptography: How do the bitslice sboxes used in the Noekeon and Serpent block ciphers work?
