DIGITAL INFORMATION PROTECTION METHOD

摘要

The invention relates to means for protecting information from unauthorized familiarization, content changes (modification) and changes to the integrity of the information during storage and transmission of information and can be used when constructing software, hardware and firmware for multi-level, including cryptographic, protection of information from familiarization and monitoring and recovery of the integrity of information. The digital information protection method comprises the use of individual coding tables, wherein individual coding values are produced by random hashing of a general combination of values, wherein the general combination of values is formed from reference combinations of code values which are not linked with one another, different values from one or more combinations can correspond to each symbol to be coded taking into account the fact that the combinations are not linked with one another and not one value in one combination can be produced from a value or several values in another combination by mathematical, logic or other methods, and the establishment of a correspondence between symbols and values to be coded in individual combinations (A1...Aq) is performed randomly in such a way that a value from the combination Aq-1 is assigned to a symbol an, wherein the selection of the combination from the range (A1...Aq) is also performed randomly.
