3  Bitcoin / Development & Technical Discussion / BIP39 HMAC-SHA512 rationale ? on: August 01, 2014, 06:12:13 AM
I was reading the BIP39 spec for generating mnemonics from bits of entropy and so derive a n word phrase. The mnemonic phrase is then stretched using 2048 rounds of sha512, with an optional salted password.

I am finding it difficult to rationalise the 2048 rounds. Assuming the default password is used ("mnemonic" according to the specification) all the 2048 rounds would do is slow down a brute force attack on guessing an n bit key.

What is the attack vector for this? The one I came up with was, if someone saw your phrase and partially memorized it, it would massively slow them down trying various combinations to discover the seed.

Am I missing something important here?
