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