Dencrypt Talk provides end-to-encrypted voice communication and live-chat on iOS-based devices. Dencrypt Talk applies the Dynamic Encryption principle, where both the encryption key and encryption algorithm change for each call.  A standard AES-encryption is wrapped by a dynamic encryption layer, which ensures that each conversation is secured by a unique, but secure encryption.

Encryption keys and algorithm selection key are generated a call setup and exchanged using the Diffie-Hellman key exchange protocol. After use, the keys and chat are overwritten and thus effectively removed from the device.

Dencrypt Talk is a user-friendly mobile application distributed to the end-users daily smartphone using the organisations Mobile Device Management system. Encrypted calls can be established as easy as regular calls. Calls are connected using Voice-over-IP and can be made using both cellular data connections (2G/3G/4G) and Wi-Fi connections.  DencryptTalk applies an individual, centrally managed phonebook defining to whom calls can be made.

DencryptTalk requires interoperability with a Dencrypt Server System deployed within the customer organisation.  The Dencrypt Server System is the backend infrastructure responsible for call management and phonebook distribution. All communication with the Dencrypt Server System is established using TLS1.2 mutual authenticated connections.
