METHOD FOR ENCODING INFORMATION WHICH IS REPRESENTED IN BINARY CODE Russian patent published in 1998 - IPC

FIELD: electric communication, computer engineering, in particular, cryptographic method and equipment. SUBSTANCE: method involves generation of encryption key, generation of ≥ data blocks, which have ≥ information pieces of binary code and application of encryption key to these data blocks. In addition method involves generation of ≥ binary vectors. Data blocks are generated by addition of binary vectors to information pieces of binary code. Binary vectors are generated in random and applied to information pieces of binary code depending on encryption key or given rule. EFFECT: increased safety against attacks which use known text or adaptive chosen text matching. 4 cl, 3 dwg
