This function encrypts the clear-text data passed in and updates the GCM tag from any previous calls. The size from XSecure_AesEncryptInit is decremented from the size passed into this function to determine when the final CSU DMA transfer of data to the AES-GCM cryptographic core.
Note: If all of the data to be encrypted is available, the XSecure_AesEncryptData function can be used instead.
Prototype
u32 XSecure_AesEncryptUpdate(XSecure_Aes *InstancePtr, const u8 *Data, u32 Size);Parameters
The following table lists the XSecure_AesEncryptUpdate function arguments.
| Name | Description |
|---|---|
| InstancePtr | Pointer to the XSecure_Aes instance. |
| Data | Pointer to the data for which encryption should be performed. |
| Size | A 32 bit variable, which holds the size of the input data in bytes, whereas the number of bytes provided should be multiples of 4. |
Returns
None
