Module nrf5x::aes
[−]
[src]
aes128 driver, nRF5X-family
Provides a simple driver for userspace applications to encrypt and decrypt messages using aes128-ctr mode on top of aes128-ecb.
Roughly, the module three buffers with the following content:
- Key
- Initial counter
- Payload, to be encrypted or decrypted
Key
The key is used for getting a key and configure it in the AES chip
Initial Counter
Counter to be used for aes-ctr and it is entered into AES to generate the the keystream. After each encryption the initial counter is incremented
Payload
Data to be encrypted or decrypted it is XOR:ed with the generated keystream
Things to highlight that can be improved:
- ECB_DATA must be a static mut [u8] and can't be located in the struct
- PAYLOAD size is restricted to 128 bytes
