DEVICE AND METHOD FOR CHECKING FRAMES TO BE USED BY AN ELECTRONIC DEVICE OF A COMMUNICATION NETWORK, ON THE BASIS OF FUNCTION TYPES AND USING PARAMETERS CONTAINED IN SAID FRAMES

摘要

The invention relates to a device (D) for checking frames of groups of bits, received by an electronic device (01) connected to a communication network (RC) and using at least one so-called non-secure-type local function. The device (D) includes checking means (MC) which, should an error occur in at least one group of bits in a frame received from the network (RC), are configured to force the electronic device (01) to use as is at least each bit group of the received frame which is representative of a parameter of a non-secure-type local function used by said electronic device (01).
