Answer
Chapter 6, Specialized Computing Domains, in the reference manual describes the system security components. Some of the key features are as follows:
- Secure boot, enforcing digital signature verification of an encrypted code image.
- On-chip, one-time programmable ROM for storing security-related information.
- Hardware cryptographic coprocessor supporting the AES-128, SHA-1, and SHA-256 encryption algorithms.
- True random number generator for creating secure cryptographic keys.
- JTAG debug controller with password-enabled secure debug capability.
- Memory interface supporting on-the-fly decryption of encrypted ROM instruction data.
