Abstract
The present invention relates to a reduced size format for transmission packet header wherein a source address is encoded together with a check code in a medical device. The packet header thus contains one single field now in place of two i.e. the check code and source address. At the receiving end, the receiver looks up the sender address from the session descriptor table, calculates the check code and then performs the same encoding with the address and the check code, thus authenticating and validating the packet.
