| Jun 19, 2017 at 10:43 | comment | added | Jay | 1. By source generating secrets I mean I have a shared randomness between two parties which is quantized to generate secret string of $1's & 0's$, 8-10 bits per sec. 2. I am using this secret string to drive PRNG. Since there is a minimum requirement of length of PRNG and I cannot use same seed for each time to drive PRNG I planned to use hashed values in each turn. So dilema is whether to give longer bit stream to hash or give short string each time. | |
| Jun 19, 2017 at 10:19 | comment | added | Maarten Bodewes♦ | What do you mean that your source generates secrets? Do you possibly mean entropy as input for a PRNG / DRBG, i.e. random number generator? In that case, why not use a DRBG algorithm instead of HKDF? Those have specific methods to update the entropy. Secret bits are bits that you tend to distribute and store so that you can reuse them, e.g. as key for a symmetric cipher. | |
