Techniques are disclosed relating to multiway communications. In some embodiments, a first electronic device initiates a multiway call between a plurality of electronic devices and exchanges a first secret with a first set of electronic devices participating during a first portion of the multiway call, the first secret being used to encrypt traffic between the first set of electronic devices. The first electronic device receives an indication that first set of participating electronic devices has changed and, in response to the indication, exchanges a second secret with a second set of electronic devices participating during a second portion of the multiway call, the second secret being used to encrypt traffic between the second set of participating electronic devices. In some embodiments, the indication identifies a second electronic device as leaving the multiway call, and the second secret is not exchanged with the second electronic device.

Secure multiway calling

A quick relay communication protocol is used by an initiating communication device (such as a wearable electronic device, e.g., a smart watch) and/or a recipient communication device (such as a companion electronic device to the wearable electronic device, e.g., a smart phone, a tablet computer or a laptop computer) to selectively communicate messages via different communication channels. Based on available connections and a communication constraint associated with a message, a processor executing a program module in an application layer in the initiating communication device provides transmission instructions to an interface circuit in the initiating communication device, which transmits a message to the recipient communication device based on the transmission instructions. When there are currently no available connections and the message is eligible to be communicated through a cloud-based relay server, the processor establishes a cloud-based connection with the recipient communication device via the relay server.
