VoiceEncryption

• Provides ‘End-to-end’ high-grade encryption for standard 3G and 4G voice communication (*)
• ‘End-to-end’ high-grade encryption for standard “FaceTime” native iPhone integrated application for voice communication, Signal or WhatsApp over internet (Wifi, 3G / 4G / 5G  data)
• Adapted to  iPhone 7 phones (**)
• ‘End-to-end’ high-grade encryption for voice communication over VoIP network (fixed-line) (***)
• Compatible with most of the fixed-line VoIP phones (CISCO CP-78xx & CP-88xx series recommended) and networks (***)
• Easy to use -“plug-and-play” without any software installation
• Provides ‘end-to-end’ high-grade encryption for voice communication
• Represents the state-of-the-art combined software and hardware solution
• Protected against physical or remote attacks
• Ensures the highest confidentiality – no servers nor remote key storing
• Has no backdoor in the system
• Half-duplex communication
• Generates ephemeral keys for the first call (devices are paired during the first call). New key generated after 10 calls
• Can be used only with one paired device

Attention ! At least two devices are required in the system to be functional.

(*) The system currently supports neither  international calls nor roaming service for 3G/4G voice calls  (must be used within the same country and local SIM cards). For international calls using  FaceTime, WhatsApp or Signal is suggested
(**) Other phone models (ex. Android-based)  might work, but Blackboxsecu cannot ensure compatibility with all of them
(***) Supported networks/phones with the following voice codecs: G711a/u; G722;G729; G729a; iLBC; G726-24,32,40; Silk (@8kHz with rate >= 10kbps, @16kHz with rate >= 15kbps)
