    • A first device in possession of a value is able to determine, without communicating the value and without communicating any information from which the value can be identified, whether a second device is also in possession of the value. The first device accomplishes this with the assistance of a third device that is able to communicate with the first device and with the second device. The second device also does not communicate the value and does not communicate any information from which the value can be identified. The first device may send additional information to the third device which, if passed to the second device, enables the second device to determine that the first device is in possession of the value. The value may be a secret.
    • 拥有价值的第一设备能够确定在不传达价值的情况下,并且不传达可以识别该值的任何信息,第二设备是否也具有该值。 第一设备通过能够与第一设备和第二设备进行通信的第三设备的协助来实现。 第二个设备也不传达该值,并且不传送可以识别该值的任何信息。 第一设备可以向第三设备发送附加信息,如果传送到第二设备,则使第二设备能够确定第一设备是否拥有该值。 价值可能是一个秘密。
