Description:The scenario description and requirements for Short White Paper



Prepare a short research paper of approximately 5 pages, double-spaced, exclusive of cover, title page, table of contents, endnotes and bibliography.
Your paper must use APA formatting with the exception that tables and figures (if used) can be inserted at the appropriate location rather than added at the end. Submit the paper in your assignment folder as a Word attachment with the following file name:yourlastnameSSB.doc



For example, a submission file would be called nanceSSB.doc



Alice, a high net worth customer, banks on-line at Super Secure Bank (SSB) and has agreed to use 3DES in communicating with SSB. One day, Alice received a statement that shows a debit of $1,000,000 from her account. On inquiring, she was told that the bank manager, Bob, transferred the money out of Alice's account and into an account of his own in an offshore bank. When reached via long distance in the Cayman Islands, Bob produced a message from Alice, properly encrypted with the agreed upon 3DES keys, saying: "Thanks for your many years of fine service, Bob. Please transfer $1,000,000 from my account to yours as a token of my esteem and appreciation. Signed, Alice."


Alice filed suit against Bob, SSB and the government of the Cayman Islands, claiming that the message was a forgery, sent by Bob himself and asking for triple damages for pain and suffering. Bob has responded by claiming that all procedures were followed properly and that Alice is filing a nuisance suit. You have been employed by SSB as a cryptographic expert to assist in the investigation of this matter, and will produce a report for the SSB Board of Directors, which will assist them in determining how to proceed in this matter


.



Your report to the Board of Directors should address the following issues



:




  • What can be determined from the facts as presented about whether Alice intended to make Bob a gift of $1,000,000?


  • Assuming SSB wishes to continue using only 3DES as its cryptographic system, what could SSB and Alice have done to protect against this controversy arising?


  • Would this controversy have arisen if SSB had been using AES rather than 3DES?


Your report should clearly address these issues, with sufficient detail and background to allow the ?cryptographically challenged? Board of Directors to understand the issues involved and formulate plans for how to approach the immediate issue with Alice, and to continue business in the future, assuming that they want to continue using 3DES.

3DES
In field of cryptography 3DES or Triple DES stands from the name TDEA (Triple Data
Encrypti
on Algorithm) block cipher that is the advance version of the DES (Data Encryption
Standard). It uses three keys for the process K1(encryption), K2 (decryption) and K3
(Encryption). The brute force attack would virtually take thousands of years in order to crack
the 3DES which is very high that the DES.
What could have happened?
The thing that would have happened here is the attack known as the “Man in the Middle”
attack or the “Play it Again” attack that is the Replay attack. Both the attacks can be applied
to this case. Clearly the Bob got the keys in dominion and what would have happened would
be the faux keys being combined and intercepted in order to clearly modify and decrypt the
actual communication done with the bank. If the Replay attack is being used...
