The next discussion in applied security is on TEMPEST.
Time: Monday, November 22 from 3-4PM
Place: NE43-516
Title: Soft Tempest
Ivan Nestlerode has agreed to lead a discussion of the paper by
Markus Kuhn and Ross Anderson:
Soft Tempest: Hidden Data Transmission Using Electromagnetic Emanations
Abstract:
It is well known that eavesdroppers can reconstruct video screen
content from radio frequency emanations. We discuss techniques that
enable the software on a computer to control the electromagnetic
radiation it transmits. This can be used for both attack and defence.
To attack a system, malicious code can encode stolen information in
the machine's RF emissions and optimise them for some combination of
reception range, receiver cost and covertness. To defend a system, a
trusted screen driver can display sensitive information using fonts
which minimise the energy of these emissions. There is also an
interesting potential application to software copyright protection.
