Professor Lars Ramkilde Knudsen

The inventer of Dynamic Encryption is professor Lars Ramkilde Knudsen, a world renowned cryptographer. He is holder of the patent together with the Technical University of Denmark and co-owner of Dencrypt. Dencrypt has the sole rights of use and rights to acquire the patent.

His main subject was for many years to break existing encryption systems, but during the last 20 years he has been the author of many crypto algorithms, which have become international standards or made it to the finals of international competitions:

  • Serpent, in AES competition the finals
  • DEAL, also in AES-final (not submitted by LRK)
  • Present, ISO/IEC 29192-2:2012
  • Grøstl, in SHA-3 final
  • Prince, light-weight cipher
  • MacDES, Mac-algorithm based on DES
  • CodeHash, ISO-standard hash-function

In 2001 professor Knudsen was behind no less than two algorithms in the finals of the international competition for the Advanced Encryption Standard (AES). One submitted by himself, and another submitted by others (due to the administrative overhead of the competition).

With the in-house expertise of professor Knudsen, Dencrypt is in the rare position of being able to offer development of proprietary algorithms, specifically tailored to customer needs.
