Claim 14:
15. A method of securely communicating a message from a beacon to an owner, the method comprising the beacon:
generating an exponentiation of a random value that is shared between the beacon and the owner;
storing the random value and the exponentiation of the random value;
generating a multiplicative inverse of the random value;
storing the multiplicative inverse of the random value;
generating a proxy value using the stored value of the multiplicative inverse and a time value;
generating a beacon packet including the exponentiation of the random value and the proxy value; and
transmitting the beacon packet, the transmitting being effective to cause a sighter to generate an end-to-end encrypted ephemeral identifier (E2EE-EID) that is usable to transmit a secure message to the owner.
