DEVICE FOR PROCESSING AND METHOD FOR TRANSMISSION OF ENCODED DATA FOR A FIRST DOMAIN IN A NETWORK PERTAINING TO A SECOND DOMAIN

摘要

The invention relates to a processing device for connection to the network of the second domain for receiving encoded data from an encoding process unique to the first domain, comprising a memory for holding a first secret unique to the first domain, decoding means (210) for encoded data by means of the first secret to give decoded data, means for encoding (210) decoded data (CW) according to an encoding process unique to the second domain such that the encoded data produced by said means for encoding can not be decoded without a second secret (KN2) unique to the second domain. The invention relates to the method for transmission of encoded data within the network of the second domain by means of the secret unique to the first domain.
