    Cryptographically secure pseudorandom number generation

      Does anyone have any experience or thoughts on implementing cryptographically secure pseudo-random or true-random number generation using WICED Smart SDK? I am looking for a way to generate nonces ( number only used once) for a crypto algorithm. pseudorandom number generators such as rand() function is not desirable for this application. The best approach would require tapping into a source of true randomness such as sampling high frequency clock (with high phase jitter) with low frequency clock. Other less secure ways would involve using time ( ss:mm:hh:dd) as seed to a an LFSR or something.
