Functions | |
| CRYSError_t | CRYS_RND_Instantiation (void *rndState_ptr, CRYS_RND_WorkBuff_t *rndWorkBuff_ptr) |
| This function initializes the RND context. It must be called at least once prior to using this context with any API that requires it as a parameter (e.g., other RND APIs, asymmetric cryptography key generation and signatures). It is called as part of ARM TrustZone CryptoCell library initialization, which initializes and returns the primary RND context. This primary context can be used as a single global context for all RND needs. Alternatively, other contexts may be initialized and used with a more limited scope (for specific applications or specific threads). The call to this function must be followed by a call to ::CRYS_RND_SetGenerateVectorFunc API to set the generate vector function. It implements referenced standard [SP800-90] - 10.2.1.3.2 - CTR-DRBG Instantiate algorithm using AES (FIPS-PUB 197) and Derivation Function (DF). More... | |
| CRYSError_t | CRYS_RND_UnInstantiation (void *rndState_ptr) |
| Clears existing RNG instantiation state. More... | |
| CRYSError_t | CRYS_RND_Reseeding (void *rndState_ptr, CRYS_RND_WorkBuff_t *rndWorkBuff_ptr) |
| This function is used for reseeding the RNG with additional entropy and additional user-provided input. (additional data should be provided by calling CRYS_RND_AddAdditionalInput prior to using this API). It implements referenced standard [SP800-90] - 10.2.1.4.2 - CTR-DRBG Reseeding algorithm, using AES (FIPS-PUB 197) and Derivation Function (DF). More... | |
| CRYSError_t | CRYS_RND_GenerateVector (void *rndState_ptr, uint16_t outSizeBytes, uint8_t *out_ptr) |
| Generates a random vector according to the algorithm defined in referenced standard [SP800-90] - 10.2.1.5.2 - CTR-DRBG. The generation algorithm uses AES (FIPS-PUB 197) and Derivation Function (DF). More... | |
| CRYSError_t | CRYS_RND_GenerateVectorInRange (void *rndState_ptr, SaSiRndGenerateVectWorkFunc_t rndGenerateVectFunc, uint32_t rndSizeInBits, uint8_t *maxVect_ptr, uint8_t *rndVect_ptr) |
| Generates a random vector with specific limitations by testing candidates (described and used in FIPS 186-4: B.1.2, B.4.2 etc.). More... | |
| CRYSError_t | CRYS_RND_AddAdditionalInput (void *rndState_ptr, uint8_t *additonalInput_ptr, uint16_t additonalInputSize) |
| Used for adding additional input/personalization data provided by the user, to be later used by the CRYS_RND_Instantiation/CRYS_RND_Reseeding/CRYS_RND_GenerateVector functions. More... | |
| CRYSError_t | CRYS_RND_EnterKatMode (void *rndState_ptr, uint8_t *entrData_ptr, uint32_t entrSize, uint8_t *nonce_ptr, uint32_t nonceSize, CRYS_RND_WorkBuff_t *workBuff_ptr) |
| The CRYS_RND_EnterKatMode function sets KAT mode bit into StateFlag of global CRYS_RND_WorkingState structure. More... | |
| void | CRYS_RND_DisableKatMode (void *rndState_ptr) |
| The CRYS_RND_DisableKatMode function disables KAT mode bit into StateFlag of global CRYS_RND_State_t structure. More... | |
