An identity is communicated (406,810,1210,1554,1658,1758) by a client device (100,1540) to a server (200,600,1000,1580,1680,1780) without requiring the identity to be disclosed to eavesdroppers and without requiring the use of symmetric or asymmetric cryptography. In one example, the identity is an identity of the client device, where the identity has been assigned to the client device by the server (200,1500) through the provisioning (306,1520) of a unique subset (206,208,210,1516) of client-identifying keys (202,1512). In another example, the identity is an identity of a group shared secret (1618,1714) that has been provisioned (708,1104,1622,1716) by the server to the client device. |
