Problem

The Rubber Hose Problem

Solution

• Server side solution to the rubber house problem
• Alice creates two data sets
• The data is encrypted and hidden with Enigma
• Alice has two passwords --> later implementation the passwords should be private keys and we should be able to access the information from. This was not implemented in Enigma yet
• One password returns the fake data and one password returns the real data
