Security is Mandatory in Bluetooth Mesh Networks
Phantom features Unparalleled Security Features
By offloading decryption, encryption, and authentication works to our CryptoCell-310, Phantom can deliver high performance in Bluetooth mesh networks.
Mesh Network, Individual Applications, and Bluetooth 5.0 Devices Are All Secure
This Cannot Be Switched Off or Reduced in Any Way
- All mesh messages are encrypted and authenticated.
- Network security, application security, and device security are addressed independently.
- Security keys can be changed during the life of the mesh network via a key refresh procedure.
- Message obfuscation makes it difficult to track messages sent within the network providing a privacy mechanism to make it difficult to track nodes.
- Mesh security protects the network against replay attacks.
- The process by which devices are added to the mesh network to become nodes, is itself a secure process.
- Nodes can be removed from network securely, in a way which prevents trash can attacks.
Three Security Keys Provide Security to Different Aspects of the Mesh and Achieve a Critical Capability in Mesh Security, that of “Separation of Concerns”
- NetKey (network key) possessed by all nodes. It allows a node to decrypt and authenticate up to the Network Layer. A relay node uses NetKey to decrypt and authenticate messages before relaying.
- AppKey (application key). Application data for specific application can only be decrypted by nodes that possess the right AppKey.
- DevKey (device key) is unique to each node. It is used for secure communication with the provisioner during provisioning process.
In a mesh network with many nodes, a lot of processing power is required for decryption and authentication at least for the relay nodes and possibly for other nodes. Phantom is embedded with an ARM CryptoCell-310 cryptographic co-processor. To achieve acceptable mesh network performance, Phantom should be used in mesh networks with many nodes.
CryptoCell-310 provides the following key features:
- Cryptographic hardware engines, providing CPU host offloading, operation, acceleration and power consumption reduction.
- Cryptography and security middleware services
- Platform security building blocks libraries
- Device life-cycle-state management
- Key management infrastructure
- Secure boot.
By offloading decryption, encryption, and authentication works to CryptoCell-310, Phantom can deliver the highest performing security of all Bluetooth mesh wireless sensor networks.
