Kryptos from Kryptos Communications, not only uses 256-bit AES to encrypt the data stream, but it also used 1024-bit RSA encryption during the iPhone-to-iPhone handshaking sequence, Infosecurity notes.
Announcing the software's availability on the Apple iTunes download marketplace Stephen W. Carnes, the firm's president, said that his firm "set out to shake up the industry with an easily installed, easy to manage technology solution to provide mobile phone users with military grade voice communications security at an unparalleled affordable price."
In use, the software runs over 3G and WiFi connection and, says Carnes, versions are in progress for the RIM BlackBerry and Google Android platforms.
Kryptos for Android should arrive in January 2011 and the RIM BlackBerry edition should arrive the following month. All versions are compatible with each other, says Carnes.
iPhone users can download the Kryptos App from iTunes on their computer or directly from the App Store on their iPhone.
According to the firm, users then activate their account with Kryptos. Each user can create their own personal individual ID. Secure calls are made peer-to-peer between users using 256 bit AES military grade encryption.
Whilst the software appears to be available on US, European and Australasian iTunes stores, Infosecurity notes that the software cannot be exported to countries such as North Korea, Cuba, Iran, Syria and selected other countries.
