The open source SafeSlinger Exchange library is a secure and easy to use method of exchanging public keys or other authentication data, with strong protection from Man-In-The-Middle (MITM) attacks. Our goal is to make exchanging public keys as simple as possible without sacrificing security. Our research paper, presented at MobiCom '13, provides a technical analysis of SafeSlinger's key exchange properties.
Library Features:
- Open source makes security audits easy.
- The only secure simultaneous key exchange for up to 10 people.
- Easy to implement and use.
- Cross-platform between mobile devices (Android and iOS) and laptop machines (Python).
- Protection from Man-In-The-Middle attacks during key exchanges.
- Exchange keys either in person or remote.
The SafeSlinger secure key exchange is implemented cross-platform for Android and iOS devices. Keys are exchanged using a simple server implementation on App Engine.
- /exchangelibrary contains the library project you can add to your own python applications.
The python exchange program currently runs for python 2.x now.
Simply execute python main.py in /exchangelibrary folder. The program will run in terminal to allow user to exchange secrets other python clients. Mobile devices can install SafeSlinger Exchange Developer's App on either Android or iOS to perform secret exchange with python clients.
- Support python 3.x.
- Design customized UI for laptop environment.
