The National Security Agency (NSA) is currently carrying out a project called “Fishbowl” that is intended to encrypt telephone communications with high levels of security within networks using commercially available cell phones, cell phone components and the open source Android software. They are working with the Department of Defense, and other national agencies, to coordinate this security effort. They are also encouraging private companies to follow suit with their own encrypted Android-based networks by making some specifications of this type of network available to the public.
On February 1st 2012, the NSA released a document called the Draft of Mobility Capability Package that summarizes the 5 major components of the this secure “Fishbowl” network: Mobile Enterprise Infrastructure, Interoperability, Secure Voice, OS/Apps and Mobile Device and Mobile Transport (Carrier).
The NSA created 100 phones from commercially available parts that are compatible with the network and capable of highly secure communication. All of the sensitive telephone conversations are handled by the NSA’s own VoIP server which runs them through an IPsec VPN with real-time transport protocol for encrypting the voices involved in every phone call. If a private company whishes to create their own secure network, they will be required to obtain they own server.
A priority of the NSA is to obtain complete interoperability so that their Information Assurance Directorate is not compromised and available across all government networks.
