The subject of this work is the presentation of a new approach to the expansion of classical cryptographic algorithms used for secret sharing and sharing data, with an additional, linguistic stage for the generation of the secret element. Such a part shall be generated in the form of a linguistic description of the shared data, built by defined sequence(More)
In the paper will be presented a new way of secret sharing algorithms expansion towards additional, linguistic stage, for the generation of the secret linguistic elements. Such a part shall be generated in the form of a linguistic description of the shared data, built by defined context-free grammar. The introduction of linguistic formalism in this scheme(More)
In this paper a new way of secret sharing algorithms expansion based on additional, linguistic stage, introduced for the generation of the secret shadow elements are presented. Such a part shall be generated in the form of a linguistic description of the shared data, built by defined sequential grammar. The introduction of linguistic formalism in this(More)
In our paper will be presented some advances in procedures used for encryption and division of secret data, as well as modern approaches for management of divided information. Computer techniques for secret information sharing aim to secure information against disclosure to unauthorized persons. The paper will describe algorithms allowing for visual(More)
