5 Security

The TI TI 15.4-Stack supports AES encryption as defined by IEEE802.15.4 specification. The application is responsible for key management, this is not done by TI 15.4-Stack initially. However, the application allows the developer to:

  • Privacy
  • Connect only trusted sources
  • Avoid tracking

TI Simplelink devices include an AES accelerator, an ECC public key generator and a TRNG to support security measures. Several security enabled examples provided within the SDK.

Table 5-1 Security Commissioning Features Supported by TI 15.4 SDK Examples
Keys Device Key
-Collector stores device key of every device
Network Key (Predefined)
-Known by every device
Encryption-Layer MAC-Layer Encryption
Decryption-Layer MAC-Layer Decryption
AES-CCM-MIC with 128-bit key
Key Storage Keys stored in MAC layer
Key Exchange ECDH P-256 (supported) Anonymous key agreement protocol
Key Derivation Algorithm AES-CMAC and TRNG
A shared secret is used to generate device key
Authentication Just Allow:
-no authentication
-no MITM protection
Default Code:
-MITM-protection
Passkey:
-Collector: must be entered
-Sensor: Displays authentication
Key Refreshment TI provided API for key refreshment
