| 14 | * |
| 15 | * The Random number generator (RNG) module provides random number |
| 16 | * generation, see \c mbedtls_ctr_drbg_random(). |
| 17 | * |
| 18 | * The block-cipher counter-mode based deterministic random |
| 19 | * bit generator (CTR_DBRG) as specified in NIST SP800-90. It needs an external |
| 20 | * source of entropy. For these purposes \c mbedtls_entropy_func() can be used. |
| 21 | * This is an implementation based on a simple entropy accumulator design. |
| 22 | * |
| 23 | * Meaning that there seems to be no practical algorithm that can guess |
| 24 | * the next bit with a probability larger than 1/2 in an output sequence. |
| 25 | * |
| 26 | * This module can be used to generate random numbers. |
