Embedded encryption device based on high order second order logistic mapping

The utility model discloses an embedded encryption device based on high order second order logistic mapping, comprising a power supply module, a data AD sampling module, a secret key driving module, a microcontroller encryption module and an embedded interface driving module. The power supply module supplies power to all modules; the AD sampling module samples the inputted data to be encrypted and provides original values changing along with the text to the secret key driving module; the secret key driving module receives the sampled data of the AD sampling module and generates the secret key changing along with the sampled data and transmit the secret key to the microcontroller encryption module; the microcontroller encryption module performs mixing and encryption on the data to be encrypted and the secret key and transmits the encrypted data to the product; and the embedded interface driving module provides the interface for the product. The embedded encryption device based on high order second order logistic mapping can be embedded into various electronic products and improves the safety of the electronic products.
