Apparatus and method for encrypting/decrypting information on basic element by element basis and encryption/decryption system using the same

摘要

An apparatus and method for encrypting/decrypting information, and the encrypting/decrypting system using the same, and a computer readable recording medium storing programs for realizing the above are disclosed. A method for encrypting information on a basic element-by-basic element basis, includes the steps of: a) receiving information to be encrypted; b) generating random number maps; c) decomposing the information into a plurality of basic elements which are classified into multiple channels; d) encrypting the basic elements and generating encrypted information; and e) outputting the encrypted information.
