Claim Text:
1. Data processing device connected to a network belonging to a second domain so as to receive data encrypted according to an encryption method specific to a first domain, comprising: a memory for containing a first secret specific to the first domain; a conditional access module that decrypts data encrypted according to an encryption method specific to the first domain and such encrypted data is received from a further device in the network belonging to the second domain, the second domain using a different encryption method than that of the first domain, and the conditional access module performs the decryption operation with the aid of first secret to obtain said decrypted data; a converter module that encrypts said data decrypted according to an encryption method specific to the second domain, so that the data encrypted by said converter module cannot be decrypted other than with the aid of a second secret specific to the second domain a memory for containing a first symmetric key as well as the encryption of said first symmetric key with the aid of the second secret specific to said second domain; said converter module converts the data decrypted with the aid of the first symmetric key; an interface that communicates:
