Re: Stealing Keys from PCs using a Radio

From: grarpamp <grarpamp@gmail.com> Subject: Stealing Keys from PCs using a Radio Even  in 1977, when I had just built my 'Dyna Micro' https://en.wikipedia.org/wiki/Single-board_computer  microprocessor trainer board, I could tell that its emanations on the AM radio band were were quite distinctive:  I could monitor the progress of programs merely by listening to an otherwise-unoccupied AM frequency.  While I wasn't particularly interested in the details at that time,  it has long been obvious that a program could be written to emit specific data, perhaps by repeating segments of code based on the information to be transmitted.               Jim Bell
