Download Secure Information Management Using Linguistic Threshold by Marek R. Ogiela PDF

By Marek R. Ogiela

In contemporary years, cryptographic thoughts for shielding and hiding mystery info were integrated in instructions of analysis on clever info administration. info might be controlled securely as a result of use of algorithms for making sure the confidentiality of information, info splitting concepts in addition to protocols for sharing details and techniques of its reconstruction.

This is why strategies of complicated splitting and reconstruction of knowledge shape the first topic of Secure info administration utilizing Linguistic Threshold Approach, whose major function is to debate the so-called linguistic threshold schemes for info sharing. An try out can be made to explain the possibilities of utilizing those innovations to create new versions of handling strategic details shared inside of a advertisement organization or a country establishment. Such details is in particular secure, and its contents are used provided that the accepted clients are enabled to entry it. This monograph makes an attempt to outline a version constitution of data circulate and for assigning info stocks to specific teams of people involved. The proposed details circulate version will be built-in into useful ideas inside of any agency or establishment, bettering the performance of its legacy details systems.

The use of sturdy mathematical cryptographic versions to regulate details constitutes a systematic innovation and an indication of the tools and possibilities of utilizing complex concepts for confidentially replacing info in initiatives assisting information circulate inside a advertisement organisation.

The interdisciplinary nature of the recommendations proposed implies that the topic of linguistic threshold schemes forming a part of clever details administration turns into a brand new problem for the learn and alertness paintings carried out.

The authors of this monograph desire that it'll advisor readers on an engaging trip during the leading edge resolution within the box of safe info management.

R. Ogiela and U. 1007/978-1-4471-5016-9_4, © Springer-Verlag London 2014 39 40 4 Model of Multilevel Information Splitting and Management in an Organization by reference to several groups ordered hierarchically, it is a hierarchical split. A layered split is thus a split made relative to a given layer, while a hierarchical split accounts for the hierarchy (dependency) of the structure or more structures relative to one another. In management theory, a hierarchy is also understood as one of the dimensions of an organisational structure, namely a system of many rungs, at the top of which there is the highest-ranking manager (or a group of managers) responsible for the operations of the organisation [5–8].

For example, we are looking for the converse of the number 5 in arithmetic mod 7. As 7 is prime ⇒ Φ(7) = 7 − 1 = 6. Thus the converse amounts to 56-1mod7 = 55mod7 = 3. The extended Euclidean Algorithm can also be used to determine the converse in modular arithmetic mod n. 2 Simple Information Splitting Methods 21 The extended Euclidean Algorithm allows the greatest common divisor d to be determined for two numbers a and b and such integers x and y which fulfil the relationship ax + by = d. This algorithm is characterised by the complexity of O((log 2 n)2 ) bit operations.

Our purpose is to demonstrate techniques and procedures for sharing information between authorised parties (individuals). Information sharing methods are founded on a mathematical base and unambiguously use it to operate correctly. These can be observed in all types of algorithms, schemes or protocols applied to information sharing problems. The reason for this is that these methods make use of concepts and functions originating from mathematical algebra. Basic methods of information sharing are used by three types of algorithms, namely: –– The vector algorithm; –– The Asmuth-Bloom algorithm [10]; –– The Karnin-Greene-Hellman algorithm [11].
