Information Security Management Based on Linguistic Sharing Techniques

Secure information splitting is used in many tasks of the intelligent sharing of secrets and key data in business organisations. The significance of information splitting depends on its nature, while the significance of information sharing may depend on its importance and the meaning it has for the organisation or institution concerned. This chapter presents models for multi-level information splitting and information management with the use of the linguistic approach and formal grammars. Such methods constitute a secure enhancement of traditional secret splitting algorithms and introduce an additional stage at which information is coded using the appropriately defined regular or context-free grammar. The many possible applications of such methods include their use for the intelligent management of important or confidential information in government institutions or businesses. Algorithms of multi-level information splitting allow information that is not available to all employees of a given organisation or its environment to be securely split or shared.
