Security
How the IMPulse protects your communication: encryption, two modes and hardware-level security.
Encryption to the core
The IMPulse uses the Voice over Blockchain Protocol (VoBP) and proven, public cryptographic standards. No marketing — just what it actually does.
AES-256
Symmetric encryption of your calls and messages with a 256-bit key.
Extended Triple Diffie-Hellman (X3DH)
Secure key exchange to establish a shared secret key.
Double Ratchet
Keys that rotate per message — the same principle modern secure messengers use.
Asymmetric keys
Public/private key pairs for identity and authentication.
Private Key (physical)
A physical key unlocks the device and your data — also on another IMPulse device.
Worm Guard
Blocks the installation of malicious programs; the OS refuses external apps.
Private Key
Private Key (physical)
A physical key unlocks the device and your data — also on another IMPulse device.
Two modes, one device
Privacy mode & Unsecure mode
Secured
Communicate through your Matrix ID — encrypted calls, messages and video calls, even without a SIM card over wifi. For everything that must stay private.
Regular SIM
A normal SIM card for everyday calls. Note: regular calls and texts can — as with any phone — be intercepted.
