easy-smpc | EasySMPC - No-Code Secure Multi-Party Computation

EasySMPC does not need an installation and can be used as a Java jar package. However, to increase portability we packaged the nessecary Java runtime with our application in an installer to build an executable for Linux, Windows and Mac OSX. This installer does not need any administrator priviledges and should be run as a user. The installers for Windows and MacOS are not signed. Thus a respective message while installing must be confirmed.
To build the executable yourself, please clone this repository and build with maven (mvn package). The assembled executable should be in the target directory. At present time some tests occasionaly fail. We're looking into that. Until those tests are passing please compile with mvn package -DskipTests.
As a study initiator, click on Create new project and enter the names of all participants, their e-mail addresses, the variables to sum up and your own confidential data. For performing the computation, you can choose between an automatic or a manual mode. a) In manual mode the users need to exchange all messages by sending and receiving e-mails manually. b) In automatic mode participants receive and import the initial message manually into EasySMPC (see 2). All further messages are exchanged automatically via their respective mailboxes. If the study initiator chooses automatic mode, all participants also have to choose automated mode. The user name and connection details provided for the automated mode will be saved for future use, the password will not be saved and must be re-entered if the study was closed in between. As a participant, you copy the message you received via email into the clipboard, click on Participate in project in EasySMPC and paste the content. You will now see the study definition and can enter your own confidential data and mail box details if applicable. As an initiator or participant, you now click on proceed. If running in automated mode, EasySMPC will automatically perform all steps until the final result is displayed. If running in manual mode, all users need to send and receive e-mails prepared by EasySMPC to perform the computation. The final perspective shows the result of the secure addition of all variables.
