## TROPIC01 Secure Element with an open architecture
The TROPIC01 secure element is built with tamper-proof technology and advanced attack countermeasures to ensure robust asset protection, securing electronic devices against a wide range of potential attacks. It securely supplies and stores the cryptographic keys of embedded solutions.
The TROPIC01 datasheet is available via [this link](https://www.nxp.com/docs/en/application-note/AN12570.pdf)

### Keys installation
For the integration with wolfSSL, there are a few pre-defined slots for the secure keys storage (the slots mapping might be changed in tropic01.h):
```sh
TROPIC01_AES_RMEM_SLOT_DEFAULT 1 // slot in R-memory for AES key
TROPIC01_AES_KEY_RMEM_SLOT 0 // slot in R-memory for AES key
TROPIC01_AES_IV_RMEM_SLOT 1 // slot in R-memory for AES IV
TROPIC01_ED25519_PUB_RMEM_SLOT_DEFAULT 2 // slot in R-memory for ED25519 Public key
TROPIC01_ED25519_PRIV_RMEM_SLOT_DEFAULT 3 //slot in R-memory for ED25519 Private key
TROPIC01_ED25519_ECC_SLOT_DEFAULT 1 // slot in ECC keys storage for both public and private keys
