| #define GNUNET_NZL | ( | l | ) | GNUNET_MAX (1, l) |
Macro used to avoid using 0 for the length of a variable-size array (Non-Zero-Length).
Basically, C standard says that "int[n] x;" is undefined if n=0. This was supposed to prevent issues with pointer aliasing. However, C compilers may conclude that n!=0 as n=0 would be undefined, and then optimize under the assumption n!=0, which could cause actual issues. Hence, when initializing an array on the stack with a variable-length that might be zero, write "int[GNUNET_NZL(n)] x;" instead of "int[n] x".

Derive the private key
Instead of expanding the private here, we already have the secret scalar as input. Use it. Note that sk is not plain SHA512 (d). sk[0..31] contains the derived private scalar sk[0..31] = h * SHA512 (d)[0..31] sk[32..63] = SHA512 (d)[32..63]
Calculate the derived zone key zk' from the derived private scalar.
Calculate r: r = SHA512 (sk[32..63] | M) where M is our message (purpose). Note that sk[32..63] is the other half of the expansion from the original, non-derived private key "d".
Temporarily put zk into S
Reduce the scalar value r
Calculate R := r * G of the signature
Calculate hram := SHA512 (R | zk' | M)
Reduce the resulting scalar value
Calculate S := r + hram * s mod L

This function derives b from a nonce and a longterm secret. In the original papers b is generated randomly. To provide abort-idempotency, b needs to be derived but still need to be UNPREDICTABLE. To ensure unpredictability a new nonce has to be used for every signature. HKDF is used internally for derivation. r0 and r1 can be derived prior by using GNUNET_CRYPTO_cs_r_derive.
