UCL COMP0064 - An application to be run by clients using our privacy-preserving Contact Discovery (CD) service (see dissertation)
This application interacts with the matching server-side application "cd_server" (to be built soon...)
Application has only been tested on Linux. Requires Go v1.14 or later and the IPFS command-line tool.
- Generate public keys from human-readable identifiers
- Local emulation of servers
- User computes shared key material with contact
- Process single contact upon manual input
- n-out-of-n server version implemented
- t-out-of-n version of the multi-server service (threshold cryptography)
- Use a blinding factor when communicating with a server
In a new terminal window, clone the repository into your GOPATH/src directory and install the application. In this example, GOPATH is set to the default value $HOME/go:
$ cd $HOME/go/src
$ git clone https://github.com/nmohnblatt/cd_client.git
$ go install github.com/nmohnblatt/cd_client
NOTE: you can check the value of GOPATH by running the command go env GOPATH
In a separate Terminal window, run the IPFS daemon:
$ ipfs daemon
Make sure that the daemon is running (check for the message "Daemon is running"). Leave it to run in the background. You can now go back to the first Terminal window and run the application by simply typing:
$ cd_client
Alternatively, you can navigate to your GOPATH/bin directory and run the application. Again in this example GOPATH is set to the default value $HOME/go:
$ cd $HOME/go/bin
$ ./cd_client
- Networked version of the service (server-side application)
- Use key material to establish IPFS meeting point
- Use key material and meeting point to establish end-to-end encryption (link w/ Signal Protocol)
- Import contacts from file
