SymmetricBlockIO
All symmetric algorithms are using the SymmetricCryptoBlockIO interface.
| Interface | Signal | Description | ||
|---|---|---|---|---|
| cmd | Stream | valid/ready | Bool | Stream handshake |
| key | Bits | The key used for the encryption/decryption | ||
| block | Bits | The block message to encrypt/decrypt | ||
| enc* | Bool | Mode encrypt (1) or decrypt (0) | ||
| rsp | Flow | valid | Bool | Data valid |
| block | Bits | The block encrypted/decrypted | ||
*this signal is optional
The timing representation of an encrypt operation looks like as below :
