The Onion Browser for iOS
The Onion Browser promises access to the dark net from your mobile phone and tunnels web traffic through The Onion Router (TOR) encrypted network.
The Onion Browser is only for iOS devices and has been developed independently of the Tor Project, which maintains its own Tor browser for desktops.
However, the Onion Browser offers similar benefits, such as masking the user's IP address and web browsing activities. It also allows users to access hidden services at .onion addresses and a one-click option to clear browser cookies.
Anyone concerned about their privacy should probably read the disclaimer by the app's developer, Mike Tigas, who notes that regardless of the app, iOS devices may still leak traffic from other services and apps on the device to network providers. Also, the Onion Browser also won't conceal who you are if you log into a service outside of the Tor network.
It's available for 99 cents from the Apple App Store.
SeeCrypt's current app for Android and iOS supports encrypted voice calls and text messages over mobile networks and wi-fi. Like other apps, it only allows encrypted communications between devices installed with the app.
The South African company says its app uses "double layer, end-to-end, military-grade encryption software".
To establish trust between two users who wish to start an encrypted data transfer, SeeCrypt relies the exchange of public keys between devices. "Two different public-key systems (RSA and ECDSA/ECDH) are used for the key negotiation and authentication, and two different stream ciphers (AES in counter mode and RC4) are used for the data encryption," it explains.
The 'double layer' refers the two stream ciphers it employs, which is meant to keep data protected in the event that of the above mentioned algorithms is broken.
SeeCrypt plans on releasing a new version of the app called SC3, which will support group messaging and Outlook Calendar synchronisation.
The app is free to install, but costs $3 a month to use. The company plans on releasing a BB10 and Windows Phone version later this year.
SafeSlinger is the product of research at Carnegie Mellon's CyLab.
According to the university, it provides the same level of messaging security as PGP, only it makes the key exchange process for encrypted communications simpler.
"When exchanging keys, you only need to compare one number and one three-word phrase with other users. When doing this comparison, you must be able to either see the other user's phone screen or hear the number and phrases spoken so you can verify the physical presence of the other user," SafeSlinger explains on its FAQ page. In other words, the way to remotely exchange keys is by making a phone call.
SafeSlinger's server is implemented on Google's App Engine, where it exchanges encrypted contact and message data.
SafeSlinger hasn't quite got all the features of a current social IM application. At the moment, there's no group messaging and users can only add one attachment to a message at a time.
