Information encryption method based on Chinese character filling game

The invention provides an information encryption method based on a Chinese character filling game, which comprises the following steps: enabling a ciphertext sender to fill word groups containing ciphertext information words into a character filling table by utilizing the character filling game, respectively encrypting the character filling game table and recorded word groups, and sending the encrypted word groups to a ciphertext receiver. In the field of Chinese information security, secret information characters are encrypted for the first time by establishing a character filling game, and simple operability is kept while the security of secret information is improved. 本发明提出了一种基于中文填字游戏的信息加密方法，利用填字游戏使密文发送者将包含密文信息字的词组填入填字表格内，再将填字游戏表格和记录下来的词组分别加密并发送给密文接收者。本发明在中文信息安全领域首次通过建立填字游戏对秘密信息文字进行加密，在增加秘密信息安全性的同时保持简易的操作性。
