Welcome to EXOS

EXOS is a system to securely exchange data between multiple parties. The principle is simple: some client encrypts data for a group of people and publishes it on a server. If anyone is interested in the data it can be fetched. EXOS does not handle permissions in the form of an access control system on the server. Any client can get the data but only those possessing the key are able to read it.

Some key properties of EXOS are:

  • Developed for mobile devices (JavaME)
  • Authentication of clients over their mobile phone number
  • Configurable cipher algorithms and key strengths
Please read the "More info" section for detailed information on data exchange and authentication.
