Functions | |
| CRYSError_t | CC_AESCCM_Init (CRYS_AESCCM_UserContext_t *ContextID_ptr, SaSiAesEncryptMode_t EncrDecrMode, CRYS_AESCCM_Key_t CCM_Key, CRYS_AESCCM_KeySize_t KeySizeId, uint32_t AdataSize, uint32_t TextSizeQ, uint8_t *N_ptr, uint8_t SizeOfN, uint8_t SizeOfT, uint32_t ccmMode) |
| This function initializes the AES CCM context. | |
| CRYSError_t | CRYS_AESCCM_BlockAdata (CRYS_AESCCM_UserContext_t *ContextID_ptr, uint8_t *DataIn_ptr, uint32_t DataInSize) |
| This function receives a CCM context and a block of additional data, and adds it to the AES MAC calculation. This API can be called only once per operation context. It should not be called in case AdataSize was set to zero in CC_AESCCM_Init. | |
| CRYSError_t | CRYS_AESCCM_BlockTextData (CRYS_AESCCM_UserContext_t *ContextID_ptr, uint8_t *DataIn_ptr, uint32_t DataInSize, uint8_t *DataOut_ptr) |
| This function can be invoked for any block of Text data whose size is a multiple of 16 bytes, excluding the last block that must be processed by CRYS_AESCCM_Finish. | |
| CEXPORT_C CRYSError_t | CRYS_AESCCM_Finish (CRYS_AESCCM_UserContext_t *ContextID_ptr, uint8_t *DataIn_ptr, uint32_t DataInSize, uint8_t *DataOut_ptr, CRYS_AESCCM_Mac_Res_t MacRes, uint8_t *SizeOfT) |
| This function must be the last to be called on the text data. It can either be called on the entire text data (if transferred as one block), or on the last block of the text data, even if total size of text data is equal to 0. It performs the same operations as CRYS_AESCCM_BlockTextData, but additionally: | |
| CIMPORT_C CRYSError_t | CC_AESCCM (SaSiAesEncryptMode_t EncrDecrMode, CRYS_AESCCM_Key_t CCM_Key, CRYS_AESCCM_KeySize_t KeySizeId, uint8_t *N_ptr, uint8_t SizeOfN, uint8_t *ADataIn_ptr, uint32_t ADataInSize, uint8_t *TextDataIn_ptr, uint32_t TextDataInSize, uint8_t *TextDataOut_ptr, uint8_t SizeOfT, CRYS_AESCCM_Mac_Res_t Mac_Res, uint32_t ccmMode) |
| AES CCM combines Counter mode encryption with CBC-MAC authentication. Input to CCM includes the following elements: | |
| CRYSError_t | CRYS_AESCCMStar_NonceGenerate (CRYS_AESCCMStar_SourceAddress_t srcAddr, uint32_t FrameCounter, uint8_t SizeOfT, CRYS_AESCCMStar_Nonce_t nonce) |
| This function receives the MAC source address, the frame counter and the MAC size and returns the required nonce for AES-CCM* as defined in ieee-802.15.4. This API should be called before CRYS_AESCCMStar and CRYS_AESCCMStar_Init, and the generated nonce should be provided to these functions. | |
