How do the secure phones work?

Technology of security phones is based on well-researched and most secure algorithms for both encryption and voice processing available today.

The phone calls are encrypted with 256 bit effective key, algorithms AES and Twofish, the secureng keys in the world. AES and Twofish double-use makes encryption more effective and eliminates all situations, when codebreak of one algorithm breaks safety of our phone calls.
