摘要

The paper will describe new cryptographic algorithms using so-called polymorphic keys. Such keys will be characterized by the fact that they will be created based on a set of clique encryption keys, designed to encode several different secrets. The polymorphic key that will be created by combining the partial keys will be able to be transformed into different forms, each of which will allow decryption of different input information. The paper will also discuss the applicability of such cryptographic solutions.
