Cryptographic Features
User available cryptographic services that are provided by the Arm CryptoCell-312 include the following:
- Encryption and decryption schemes, including:
- Advanced Encryption Standard (AES-128, AES-192, AES-256)
- RSA (RSA-2048, RSA-3072, RSA-4096)
- ChaCha (ChaCha20, ChaCha20-Poly1305)
- Elliptic Curve Integrated Encryption Scheme (ECIES)
- Galois Counter Mode (GCM) support, typically using AES
- Hash schemes, including:
- Secure Hash Algorithms (SHA-1, SHA-224, SHA-256, SHA-384, SHA-512)
- Message Authentication Coding, including:
- Hash Message Authentication Code (HMAC), typically using SHA-256
- Cipher-based Message Authentication Code (CMAC), typically using AES
- Elliptic Curve Digital Signature Algorithm (ECDSA)
- Secure Remote Password (SRP)
- Key generation and exchange algorithms, including:
- Elliptic-Curve Diffie-Hellman (ECDH)
- DHM key exchange (DHM)
- CCM (CRT CBC-Mac, or Counter mode cipher block chaining message authentication codes calculated using a counter-based initialization vector)
- CTR-DRBG (Counter mode deterministic random bit/byte generator)
- Key Derivation
These services allow for development of custom proprietary security solutions.
