FIELD: radio engineering, communication.SUBSTANCE: method of encrypting an n-bit data unit M includes generating a secret key by generating subkeys Q and R and auxiliary subkeys in form of mutually simple multi-bit binary numbers mand m, generating an auxiliary n-bit data unit T, generating an n-bit auxiliary cryptogram Cby performing a block encryption operation E over the M depending on Q using the formula C=E(M), generating n-bit auxiliary cryptograms Cby performing a block encryption operation E over T depending on R using the formula C=E(T), generating a cryptogram C in form of a solution of a system of two identities C?Cmodmand C?Cmodmwith unknown C. In a particular version of the method, mand mare prime numbers.EFFECT: high level of security of information encrypted using said method.2 cl |
