Scenario:
Sandra, a high net worth customer, banks on-line at Megagargantuan Bank and Trust
(MBT) and has agreed to use 3DES (also known as Triple DES) in communicating with
MBT. One day, Sandra received a statement showing a debit of $1,000,000 from her
account. On inquiring, she was told that the bank manager, Janet, transferred the money
out of Sandra’s account and into an account of her own in an offshore bank. When
reached via long distance in the Cayman Islands, Janet produced a message from Sandra,
properly encrypted with the agreed upon DES keys, saying: “Thanks for your many years
of fine service, Janet. Please transfer $1,000,000 from my account to yours as a token of
my esteem and appreciation. Signed, Sandra.”
Sandra filed suit against Janet, MBT and the government of the Cayman Islands,
claiming that the message was a forgery, sent by Janet herself and asking for triple
damages for pain and suffering. MBT filed a countersuit against Sandra, claiming that all
procedures were followed properly and that Sandra is filing a nuisance suit. You are
called in as an expert witness on the cryptographic issues of the case.
