One-Time Pad (OTP) encryption
Mathematically unbreakable – the only truly secure encryption system for your confidential and private communication.
Each device generates unique encryption keys by a built-in hardware True Random Number Generator (TRNG), tested according to NIST SP 800-22 and FIPS PUB 140-2.
Entangle Light Gap Connection
A solution, designed in-house, that uses light signals for data transfer between the device and smartphone. The device's only connection to the outside world.
Entangle devices are completely isolated from common network capabilities like Wi-Fi, 4/5G, Bluetooth, etc.
Negligible emissions of radio & electrical signals
The uniquely designed device hardware minimizes the possibilities of side-channel attacks (SCA).
The Entangle device is deliberately designed as simple as possible, possessing no unnecessary components or features.
Entangle is employing a quantum-resistant and the only truly secure encrypted message exchange technique, mathematically proven unbreakable.
NIST & FIPS
The built-in hardware TRNG is NIST SP 800-22 and FIPS PUB 140-2 compliant.
Manufacturing takes place in the European Union. Entangle devices are built with CE certified materials, making the technology reliable and secure.
Entangle uses One-Time-Pad encryption technique which is secure against an attack by a quantum computer. Using brute force attack with unlimited quantum computing power – exhaustive trial and error methods to find the message plaintext – the attacker would gain countless results of meaningful text and without the key, he has no way of finding out which plaintext is the original message.
Does Entangle have access to users’ messages?
Messages outside users’ device are impossible to decipher. Entangle provides the communication infrastructure (servers and software) necessary for message exchange, and we handle encrypted messages on our servers, but we don't have access to plaintext messages.
Where are the encryption keys stored?
Encryption keys are exclusively stored on users' devices. This way, we ensure that nobody from the outside has access to them. Besides that, Entangle devices have no connections to the outside world – no Wi-Fi, Bluetooth, or USB. The only way a third party could obtain a user's encryption key is by gaining physical access to the Entangle device.
Can I use Entangle for calls and data file transfers?
Currently, Entangle devices only provide secure text message exchange, but voice communication and data transfer functionalities are in development. We suggest that you subscribe to our newsletter so that we can inform you when these functionalities are launched.
What languages are supported on Entangle devices?
Currently, only English. French, Spanish, and German are in development. Other languages can be implemented upon request.
