BLE->CS->15. DRBG-5

Today we continue to explain the subsequent content of DRBG.——- DRBG nonce V (i.e., VDRBG) As described in Section 3.1.5, the instantiation of the random number V vector represents the initial value of the DRBG increment function. From this initial value, multiple random number counter fields are defined, as shown in Table 3.3. Each counter … Read more

BLE to CS: DRBG-4

Today we continue to explain the content related to DRBG.——- Random Bit Generation Function CS_DRBG The random bit generation function CS_DRBG utilizes the secure function e (see [Vol 3] Part H Section 2.2.1) to generate a new 128-bit random bit sequence. The instantiated key and random number vector V values are detailed in Section 3. … Read more
