Secure computer architecture

A computer program product comprising a non-transitory computer readable medium having a computer readable program recorded thereon, wherein the computer readable program, when executed on a component of a computing device, causes the component to:

• initiate transmission of a continuous stream of frames across a data communication link, wherein the continuous stream of frames is a stream of frames in which each frame comprises data and there are no fixed timing interval breaks between frames in the continuous stream;
• determine whether data is received from a source for transmission across the data communication link as part of the continuous stream of frames;
• convert the data to one or more first fixed length frames and transmit the one or more first fixed length frames on the data communication link as part of the continuous stream of frames in response to determining that data is received from the source for transmission across the data communication link;
• and
• transmit, as part of the continuous stream of frames, one or more second fixed length frames comprising fill data, for inclusion in the frames of the continuous stream in response to determining that data is not received from the source for transmission across the data communication link as part of the continuous stream, wherein the component continuously performs the determine, convert, and transmit operations while the continuous stream is active such that the continuous stream comprises a combination of the one or more first fixed length frames in response to data being received from the source for transmission across the data communication link and the one or more second fixed length frames in response to data not being received from the source for transmission across the data communication link.
