Signal encryption using random function andwavelet transform

Abstract EN

An advanced new method for encryption is proposed in this research using random function and wavelet transform (DWT).

Encryption process had been done on stages, where it firstly used wavelet transform as a tool of feature extraction of data and signals to be encrypted, and then exclude these distinguished features.

Secondly, the processes of extraction and exclusion were followed by another encryption process using random function.

The result of all these encryption processes was fully unrecognized signals and data.

In decryption stage, algorithms were designed to restore the encrypted data and signals to their original states and dimensions efficiently.
