Nokia N91

Our specially modified Encrypted Nokia N91 cell phone with built-in encryption software converts your voice to encrypted data using a constantly changing mathematical formula. It uses a 1024 bit asymmetric key based upon the RSA algorithm and a changing session key which modifies the encryption algorithm every second.

The Nokia N91 WCDMA/EDGE music device combines stereo sound, storage capacity for 3000 songs, over-the-air music downloads, access to your music collection with the latest smartphone functionalities - MMS, e-mail, Bluetooth, WAP 2.0 (XHTML) browsing and Java(tm) technology, WLAN and a 2 megapixel camera.

Encryption Software
• Dual layered RSA 1024 bit /AES 256 bit military grade encryption
• 4,096 bit Diffie-Hellman key exchange (key randomly generated for each call)
• Superior audio quality
• Lowest audio latency (delay)
• Improved security features
• Software-only solution - no additional hardware required

Service requirement: GSM cellular service with CSD (circuit switched data) support. Some carriers may provide a separate number to transmit and receive data. User may need to switch mobile carrier to one supporting CSD (also known as "data call').
