1. An electronic receiving device for receiving data via an asynchronous communication network including at least one elementary network, the electronic device being configured to be connected to said elementary network and comprising:
a receiver configured to receive several successive data frames via the asynchronous communication network, each frame being sent over said elementary network according to a predefined sending table and with a minimum time gap between sending time instants of two successive frames,
a verifier configured, for at least two received data frames, to estimate a network jitter from the minimum time gap and reception time instants of at least two frames received on said elementary network, then to compare the estimated network jitter to an authorized range of network jitter values,
wherein the verifier is configured to estimate the network jitter from a duration separating two reception time instants and from a predefined inter-frame time period, the predefined inter-frame time period being a function of the minimum time gap, and
wherein the predefined inter-frame time period is equal to the minimum time gap divided by an oversampling factor.
