Peripheral Security[edit | edit source]
The RZ/T2H SoC provides a security mechanism for secure product protection including secure boot mode, peripherals access (UART, USB, JTAG), cryptographic accelerators, user program encryption and more.
Description[edit | edit source]
The RZ/T2H security features are listed below:
- Secure boot mode (in which a user program is protected by encryption) can be selected for the products that support security functions
- JTAG authentication
- SCI/USB boot authentication: check access permission for UART boot mode
- Cryptographic accelerators
- Symmetric Cipher: AES 128/192/256 bits with CBC/ECB/CTR/GCM/XTS
- Asymmetric Cipher: ECC 256 bits, RSA 1024/2048/3072 bits, RSAES-OAEP
- Hash: SHA-1, SHA-2
- Message authentication: HMAC, CMAC, GMAC
- Signature algorithms: ECDSA with NIST P-256, RSASSA-PSS, RSASSA-PKCS1
- TRNG
- Cortex-A55 Crypto Extension
- ARM® TrustZone® technology
