1. A method of assuring integrity of a data set between multiple devices, the method comprising:
- generating a normalizing factor at a first device;
calculating a first integrity mechanism based on the data set at the first device and the normalizing factor; and
sending the normalizing factor and the first integrity mechanism from the first device to at least a second device,wherein the first device is a source device of the data set whose integrity is being assured, and the second device is a destination device of the data set whose integrity is being assured.

Abstract
One embodiment disclosed relates to a method of assuring integrity of a data set between multiple devices. A normalizing factor is generated at a first device. Based on the data set at the first device and the normalizing factor, a first integrity mechanism is calculated. The normalizing factor and the first integrity mechanism are sent from the first device to at least a second device. Other embodiments are also disclosed.
