• Abstract:

  The current conventional office data encryption method mainly encodes the original data and encrypts the encoding correspondence to guarantee the security of the data, which leads to poor encryption effect due to the neglect of the expansion of the key as well as the replacement processing. In this regard, the automatic encryption method of office data based on chaotic sequence is proposed. Firstly, the required chaotic sequence is generated by selecting the chaotic mapping and preprocessed, and the simulated key is shifted and self-weighted to select part of the key bits that meet the arithmetic requirements for the expansion and substitution process. Then the key stream generated by Logistic mapping is used to generate a configurable 64bit original key after data processing. Finally, one layer encryption as well as two layer encryption is performed on the office data respectively. In the experiments, the encryption effect of the proposed method is verified. The analysis of the experimental results shows that when the proposed method is used to encrypt the office data, the ciphertexts are more different and have a more ideal encryption effect.
