- Abstract
- There is proposed a method for information transformation including in a single process of the data transformation both the block encryption and the error correction. The proposed method is based on insetting the redundancy in the form of two labels that are preliminary fixed and represent binary vectors. The transformed data are encrypted using a block cipher. One of the redundancy labels is imbedded before the encryption process. The second one is imbedded after the encryption procedure followed by the additional cryptographic transformation that extends the transformed data block. The additional cryptographic transformation represents a process of solving a system of two linear equations with two unknowns, in which the subkeys are used as coefficients of the linear equations. The first redundancy label is used to reduce the probability of false decoding. The second label is used to reduce significantly the number of the potentially possible combinations of the errors. Due to the last the performance of the decryption procedure is essentially higher than in the known methods for error-correcting ciphering.
