Scenario:
Angela changes banks following her troubles with TBT. At her new bank, First Security Trust (FST), RSA is used as the cryptographic system. Angela creates a key pair and supplies to Florence, an officer of FST who will handle her account, with her public key {eA, nA}, securing her private key {dA, nA} on a thumb drive which he keeps locked in a wall safe at her home. In turn, Florence gave Angela access to a key server maintained by FST so that she can readily obtain Florence’ current public key {eF, nF} whenever she needs to communicate
securely with Florence.
Things are fine for several months until Angela sends Florence a message m asking about current interest rates on Certificates of Deposit issued by FST. As shown below, she enciphers the message first, and then signs it
C = (mef mod nf )dA mod nA
Where C is the encrypted message and m is the plaintext message.
A few days later, Angela received a statement that shows a debit of $1,500,000 from her account. On inquiring, she was told that Florence transferred the money out of Angela’s account into an account of her own in a bank on the Caribbean island of Nevis, where she moved. When reached via long distance in Nevis, Florence produced a message ’g’ from Angela saying:
“Thanks for your excellent service, Florence. Please transfer $1,500,000 from my account to yours as a token of my esteem and appreciation. Signed, Angela.”
Angela files suit against Florence, FST and the government of the Nevis, claiming that the message was a forgery sent by Florence herself, asking for triple damages for pain and suffering. Florence has responded by claiming that all procedures were followed properly and that Angela is filing a nuisance suit.
You have been employed by FST as a cryptographic expert to assist in the investigation of this matter and help them decide what to do with Angela issue. You obtain Florence’s private key from the UST server, and the cipher text C, and calculate
g= (CeAmod nA)dFmod nf
Where g is the plain text message which was obtained the cipher text C
d Is Florence’s Private key Your report to the FST Board of Directors should address the following issues:
From the facts as presented what can be determined about Angela’s intentions to make Florence a gift of $1,500,000? How did the fact help you in forming your conclusion?
What is the significance of Nevis Island?
What is the significance of Angela’s message to Florence asking for interest rates?
Assuming FST wishes to continue using RSA as its cryptographic system, what UST and Angela could have done to protect against this controversy arising?
How to proceed in the litigation
Your report should clearly address these issues including recommendation for the Angela’s suit, with sufficient detail and background to allow the Board of Directors who are cryptographically challenged to understand the issues involved and formulate plans for how to approach the immediate issue with Angela, and to continue business in the future, assuming that they want to continue using only RSA. Assume that the directors do not know what RSA is and/or how it works
