Demo of Cellcrypt Mobile, a standard downloadable app, making an encrypted voice call between an iPhone 4 on Wi-Fi and a iPhone 4 on 3G. The call is encrypted using RC4 256-bit then AES 256-bit and authenticated using 2048-bit RSA & ECDSA. The key exchange uses Elliptic Curve Diffie Hellman & RSA. Cellcrypt Mobile runs on a variety of platforms and so I also show a call between the iPhone 4 and a Nokia E72.
