METHOD AND APPARATUS FOR ENCODING AND DECODING INFORMATION

A method for encoding a set of initial symbols from a plurality of elemental symbols. The method generates for each symbol from the set of initial symbols, a first parameter representing a number of intervals of a numeric axis, a plurality of second parameters representing a plurality of lengths of intervals of the numeric axis, and a plurality of third parameters representing a plurality of locations, respectively. The method generates for each symbol from the first plurality of parameters, from the second plurality of parameters, and from the third plurality of parameters, a key function for each symbol, respectively. The method transforms for each symbol using the respective key function, the set of initial symbols to a plurality of individual symbols, respectively. Using the plurality of key symbols as a key, the method encodes the set of initial symbols as a set of encoded symbols, respectively. The symbol unit optionally may generate with a supplemental function, for each symbol, a supplemental symbol, and combine a supplemental symbol with a respective individual symbol to generate a key symbol. The encryptor, using the plurality of key symbols as a key, encodes the set of initial symbols as an set of encoded symbols, respectively.
