<p>The process transfers information from one domain to another, using different coding. The information is decoded using a first secret, and re-encoded using a second secret, each secret only being known to the one domain. The processing device provides a connection to the network of a second domain, for receiving encoded data from an encoding process unique to the first domain. The device comprises a memory for holding a first secret which is unique to the first domain. A decoding device (210) handles encoded data by means of the first secret in order to provide decoded data. A further encoding device encodes the decoded data (CW) according to an encoding process which is unique to the second domain, such that the encoded data produced cannot be decoded without a second secret (KN2) unique to the second domain.</p> |
