About Dynamic Encryption

(PDF, Rijmen, opinion)

Dynamic Encryption has been called “state of art in cryptology” by Vincent Rijmen, author of the AES encryption standard and a world-renowned cryptologist.

Dynamic Encryption provides extra protection, as not only the encryption keys but also the configuration of the crypto system change for each data transfer. The inner encryption algorithm (e.g. AES-256 or national algorithm) is wrapped by an outer Dynamic Encryption algorithm. When the data transfer is complete, the encryption algorithm is discarded, which leaves no way of introducing master keys for data inspection.

Cryptanalysis (code breaking) normally requires large amounts of data to be encrypted with the same method. As Dynamic Encryption is constantly mutating, cryptanalysis is made practically impossible.

This is the moving target defence strategy applied to cryptography: any potential breach would only reveal the content of a single data transaction, as the subsequent transaction will be encrypted in a different way. The Dynamic Encryption principle extends the lifetime of a cryptosystem, as the outer layer shields the inner algorithm from attacks.

The Dynamic Encryption principle was invented in 2003 by Professor Lars Ramkilde Knudsen, one of five finalists of the international AES competition. Dencrypt has the exclusive right to use and acquire the patent.
