METHOD AND DEVICE FOR PROTECTING THE INTEGRITY OF DATA TRANSMITTED OVER A NETWORK

摘要

The method of transmitting data (550) over a network (515), from a sending application (520) to a receiving application (525) comprises: - a step of coding said data, by said sending application, by implementing a predefined rule - a step of detecting alteration of at least one item of data transmitted, by said receiving application, by implementing said predefined rule and - in case an alteration of a data item is detected, a step of restoring the altered data item. In embodiments, in the course of the coding step, in the course of the alteration detection step and in the course of the restoration step, a cyclic redundancy check or an encryption is implemented.
