Abstract
Method for decrypting, within a wireless communication device, a sequence of encrypted packets received via a wireless communication channel between the communication device and a cell assigned to this device, comprising for each packet the following steps: —the computation of an encrypting sequence corresponding to the packet (); and —the decrypting of the packet with the aid of the said encrypting sequence (). In this method, the encrypting sequences are computed before the reception of the packets while the reception quality is above a threshold (, TH) and an indication of change of cell is not received ().
