Dencrypt formed following the creation of the patent pending for dynamic encryption, which was invented by Lars Ramkilde Knudsen, a professor in the Department of Applied Mathematics and Computer Science at the Technical University of Denmark. Today, NATO and the Danish Defence use its products to protect against eavesdropping in insecure tele and data networks.
The company's product range includes Dencrypt Talk - a simple app that is designed for smartphones. Combining advanced cryptography and a user-friendly app ensures that placing a cryptographically secured call is as easy as making a normal one. There is no need for a second, more secure phone.
Dencrypt Talk supports group calls that allow up to five or six people to talk at one time - depending on available bandwidth - and LiveChat, which does not store chat history.
This app is Common Criteria-certified, guaranteeing quality for the software and security features of the app, as well as the server that controls user accounts and call groups. Dencrypt's server can be bought as a cloud service or operated in-house by customers.
Dynamic encryption extends the life cycle of any cryptoalgorithm by adding a secondary, mutating cryptographic layer. The unpredictability of the algorithm strengthens the system because no attacker will know how to attack it, unlike standard encryption algorithms.
With Dencrypt Talk, a random algorithm is generated for each phone call. New keys are also created for every conversation. When a telephone call has ended, all traces of the algorithm and keys are deleted.
Vincent Rijmen, co-inventor of the Advanced Encryption Standard, wrote in 2017, "Dynamic encryption is sound and secure, according to the state-of-art in cryptology."
Dencrypt engages in development projects to implement dynamic encryption into other companies' products, such as satellites systems and internet-of-things devices.
