A system for encoding and decoding data words including an anti-analysis encoder unit for receiving an original plaintext and producing a recoded data, a data compression unit for receiving the recoded data and producing a compressed recoded data, and an encryption unit for receiving the compressed recoded data and producing an encrypted data. The recoded data has an increased non-correlatable data redundancy compared with the original plaintext in order to mask the statistical distribution of characters in the plaintext data. The system of the present invention further includes a decryption unit for receiving the encrypted data and producing a decrypted data, a data decompression unit for receiving the decrypted data and producing an uncompressed recoded data, and an anti-analysis decoder unit for receiving the uncompressed recoded data and producing a recovered plaintext that corresponds with the original plaintext.
