FIELD: radio engineering, communication.
SUBSTANCE: source device and a target device may attempt to form a secure communication session whereby encrypted messages may be transmitted over an unsecured network, such as the Internet. However, the exchange of many messages when establishing the communication session may involve considerable latency and computational resources, particularly in scenarios featuring many communication sessions (e.g., peer-to-peer communication sessions.). Techniques for initiating a communication session may be devised, which enable the initiation of a communication session with only two exchanged messages, or even with a single message transmitted from the source device to the target device.
EFFECT: some embodiments of said techniques may also permit the inclusion of useful security features, such as authentication via public certificate to detect message interception attacks and key replacement without increasing the number of messages involved in the initiation of the communication session.
