Abstract
In a method for providing a secure communication between two devices, a first device generates a random key (Ci) and transfers this key to a second device in a first message encrypted using a plublic key. The second device decrypts the first encrypted message by means of a corresponding secret key to obtain the random key (Ci) and this random key is used to encrypt and decrypt all transmissions between these devices. In a decoder for a pay TV system, comprising a conditional access module and a smart card, this method is applied to provide a secure communication between the control access module and the smart card and/or between the decoder and the conditional access module.
