Field Documentation

◆ algoType

uint32_t DTHE_AES_Params::algoType

< Algorithm to be performed by the AES Driver

◆ opType

uint32_t DTHE_AES_Params::opType

Operation to be performed by the AES Driver.

◆ useKEKMode

Bool DTHE_AES_Params::useKEKMode

< This is a boolean flag which indicates if the KEK mode is to be used or not. If this is set to TRUE then the 'ptrKey' below is not used. The operation mode is ignored and this is only used for encryption.

◆ ptrKey

uint32_t* DTHE_AES_Params::ptrKey

< Pointer to the key to be used to perform the decryption. The driver supports AES-CBC with 256bit keys. This is only valid if the KEK mode flag above is set to be FALSE.

◆ keyLen

uint8_t DTHE_AES_Params::keyLen

Length of the Key.

◆ ptrIV

uint32_t* DTHE_AES_Params::ptrIV

< Pointer to the Initialization Vector to be used.

◆ dataLenBytes

uint32_t DTHE_AES_Params::dataLenBytes

< Size of the data in bytes

◆ ptrEncryptedData

uint32_t* DTHE_AES_Params::ptrEncryptedData

< Pointer to the encrypted data buffer:

Decryption Operation Mode:

This is used as an input parameter and is used to point to the location of the encrypted data buffer.

Encryption Operation Mode:

This is used as an output parameter and is the location where the encrypted data will be present.

◆ ptrPlainTextData

uint32_t* DTHE_AES_Params::ptrPlainTextData

< Pointer to the Plain Text data buffer:
