System, Apparatus and Method for Secure Coordination of a Rendezvous Point for Distributed Devices Using Entropy Multiplexing

A system comprising:

• a first device including at least one first memory and at least one first processor coupled to the at least one first memory;
• and
• a second device including at least one second memory and at least one second processor coupled to the at least one second memory;
• the at least one first and second processors to perform operations comprising:
• generating, when the first device is included a first segment of a first network and the second device is included a second segment of the first network, (a)(i) in the first device a pseudo-random seed tree from a root seed, and (a)(ii) in the second device an additional instance of the pseudo-random seed tree from an additional instance of the root seed;
• accessing (b)(i) in the first device at a first time period a random number of the pseudo-random seed tree that corresponds to the first time, and (b)(ii) in the second device at the first time period the random number of the additional instance of the pseudo-random seed tree that corresponds to the first time period;
• generating, in the first device, (c)(i) a rendezvous point name based on the random number, and (c)(ii) a rendezvous point record that includes the rendezvous point name;
• generating, in the second device, (d)(i) the rendezvous point name based on the random number, and (d)(ii) an additional rendezvous point record that includes the rendezvous point name;
• sending, from the first device, (e)(i) the rendezvous record to an exchange server, and (e)(ii) an encrypted message to the second device via the exchange server;
• and
• sending, from the second device, the additional rendezvous record to the exchange server and, based on the rendezvous record and the additional rendezvous record, receiving the encrypted message at the second device via the exchange server.

An apparatus comprising:

• a first device including at least one first memory and at least one first processor coupled to the at least one first memory, the at least one first processor to perform operations comprising:
• determining a pseudo-random seed tree from a root seed;
• when the first device is included in a first segment of a first network, accessing at a first time a random value at a level of the pseudo-random seed tree that corresponds to the first time;
• determining in the first device, (a)(i) a rendezvous point name based on the random value, and (a)(ii) a rendezvous point record, which includes the rendezvous point name, to enable communication between the first device and a second device that is in a second segment of the first network;
• and
• communicating (b)(i) the rendezvous record to an exchange server, and (b)(ii) an encrypted message to the second device via the exchange server.
