METHOD FOR ENCODING INFORMATION WHICH IS REPRESENTED IN BINARY CODE |
摘要 |
FIELD: electric communication, computer engineering, in particular, cryptographic method and equipment. SUBSTANCE: method involves generation of encryption key, generation of <EMI ID=0.257 HE=3 WI=3 TI=CHI> data blocks, which have <EMI ID=0.258 HE=3 WI=3 TI=CHI> information pieces of binary code and application of encryption key to these data blocks. In addition method involves generation of <EMI ID=0.259 HE=3 WI=3 TI=CHI> 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 dwgi
