Abstract
A method of establishing a session key K.sub.s for a session between a unit for descrambling scrambled multimedia signals and a removable cryptographic unit, wherein: --one of the units sends (steps 166, 184) the other unit a message containing a received random number, a term .alpha. and a signature of the random number and/or the term a produced using a private key K.sub.3pr, then--the other unit verifies (steps 168, 192) the signature using a public key K.sub.3pu corresponding to the private key (K.sub.3pr) and compares (steps 174, 198) the random number received to that sent, and--if the signature is incorrect or if the random number received does not match that sent, then the subsequent steps for establishing the session key are not carried out.
