* This manages secure sessions and provides framework for multiple transports. * The application can use protocomm layer directly to have application specific extensions for provisioning (or non-provisioning) use cases. * Following features are available for provisioning : * Security - Security0 (no security), Security1 (curve25519 key exchange + AES-CTR encryption) * Proof-of-possession support for Security1 * Protocomm requires specific protocol buffer modules for compilation which can be generated from the `.proto` files in the `proto` directory using make.
