Abstract
The strength of the crypto-semantic method (CSM) of text data protection based on the use of lexicographical systems in the form of applied linguistic corpora within the formally defined restrictions of selected spheres of applied uses has been analyzed. The levels of cryptographic strength provided by the crypto-semantic method of data protection with due regard of a cryptanalyst’s resource capabilities are determined. The conditions under which the CSM provides absolute guarantee of text data protection from confidentiality compromise are determined.
Highlights
In [1], a text data protection method entitled ―cryptosemantic method‖ (CSM) is suggested
The cryptanalyst is able to obtain the data on the statistical properties of the application area thesaurus to the extent enabling to construct a function of distribution of a priori probabilities of occurrence of semantic units of the predefined table form on the receiving end of the crypto-semantic method (CSM) protection system encoder;
The strength of the crypto-semantic method (CSM) of text data protection based on the use of lexicographical systems in the form of applied linguistic corpora has been analysed
