Abstract

The invention discloses a data encryption method. The method includes steps of acquiring a user key preset in a security chip and valid data bits in the user key when to-be-encrypted data is detected; determining an embedding rule for embedding the valid data bits in the to-be-encrypted data according to the structure attribute of the user key or a received customized instruction; embedding the valid data bits in corresponding positions of a data bit sequence of the to-be-encrypted data according to the embedding rule; using the embedded positions of the valid data bits as check data, and loading the check data onto the data sequence in which the valid data bits are embedded in order to generate encrypted data. The invention also discloses a security chip and a computer readable storage medium. The data encryption method can increase the cracking difficulty of encrypted data.

Description

technical field [0001] The invention relates to the technical field of information security, in particular to a data encryption method, a security chip and a computer-readable storage medium. Background technique [0002] With the development of wireless communication technology, people pay more and more attention to information security. Encrypting data is the main means to ensure information security. At present, most wifi communication devices often use WPA (Wi-Fi Protected Access) for encryption, and the commonly used AES (Advanced Encryption Standard) encryption algorithm. [0003] However, these algorithms encrypt fixed packet lengths such as 128, 192, and 256-bit data. The encrypted data bits are widely known. If hackers and other intruders collect enough data and encrypted data frames sent by the device, the encrypted The analysis of the data frame will eventually draw the encryption rules, crack the login password of the wifi device, invade the wifi communication d...
