It is illegal to interfere with telecommunications. Not sure about 
anything specific about altering the content, but there are provisions 
regarding tampering with equipment. There are of course laws regarding 
accessing and interfering with computers.

My doctoral research is/will be focussing upon the interface between law 
and technology with respect to the privacy and integrity of personal 
data held by governments (especially in information management contexts) 
- I haven't got to specific telecommunications issues just yet.

The real problem is being able to identify when a data stream has been 
tampered with - until you have reason to investigate, no law will be of 
much help.

This is not legal advice, it's an opinion, my opinion. Yours may differ. 
That's great.
