NETWORK OPTIMIZATION FOR SECURE CONNECTION ESTABLISHMENT OR SECURE MESSAGING

摘要

A first device is configured to receive an instruction to establish a secure connection with a second device or to send a secure message to the second device. The instruction may include a secure connection invitation or a message. The first device may send information, associated with the second device, to a first server; receive a response from the first server; obtain parameters based on the response indicating that the second device is subscribed to the first server; communicate the parameters to the first server; receive a parameters identifier associated with the parameters; store the parameters identifier in the secure connection invitation or the message; and send the secure connection invitation or the message to the second device. The second device may receive the parameters identifier to obtain the parameters to establish the secure connection or to decrypt the secure message.
