Encryption Technology — HCIA™


The encryption and decryption of information has long been an important tool for preventing unauthorized and undesired access to secret information, whether this information is stored in a computer, on a computer-readable storage medium, or transmitted between two parties over some communication link. With the evolution of computers and telecommunications technology, the quantity of information created and exchanged on a day to day basis is ever increasing and ever more accessible. The need to prevent unwanted access to, and possible tampering with, this information in a manner that is rapid to implement but ensures high security is therefore greater than ever before.

HCIA - a New Way of Encryption

With the introduction of our encryption method the High Complexity Interpretation Algorithm (HCIA™) a new technology for encryption is born. The HCIA™ system is based on the irreversibility of executional output and description problems of language. This could sound complicated (it’s not trivial anyway), but we will give it a try.

The use of static algorithms and time-invariant methods as in conventional symmetric cryptography is avoided by interpretation of the key and the message as an encoding of a new algorithm. Practically you will get a new system, or loosely speaking a new algorithm, for every encryption you make. HCIA™ is an “encryption system creator”.

This gives the cryptanalyst who tries to break the system a “new algorithm”, that is unknown to him, to analyze for every intercepted message!
